Geyser safety valve installation is a must in order to comply with geyser fittings requirements in South Africa. Safety valve serves to protect water heating cylinder from possible explosion that results from faulty thermostats. Sometimes a geyser thermostat can get stuck on one position, and that may result in overheating.
In such cases, the heating element will continue to boil water since the “monitor” is stuck and there is no instruction to cut off power supply to the geyser. This creates pressure from the steam built up in a closed cylinder.
If the geyser safety valve is not installed, such a case will result in geyser explosion.
The safety valve works by opening to let out air and reduce pressure whenever the pressure rises beyond the safe value.
The second function of this valve is over pressurizing. This normally occurs when your pressure reducing valve fails. When that happens, there is no reducing of pressure from municipal lines.
The safety valve will immediately sense such a surge in pressure and open to release extra pressure out.
Installation of Geyser Safety Valve
Alternatively, turn off the water at the house supply valve.
After that, the removal of the relief valve is done by turning it anticlockwise with a large pipe wrench. Then application of a sealant to the threads of the new relief valve takes place.
Finally, the valve is inserted into the opening in the tank and threaded in. The valve should be tight enough not to allow water to escape.
When you have a geyser not heating up, there are 3 possibilities. The first one is no power supply. If a geyser is not receiving power, it will obviously not perform its function. Therefore if you face a geyser issue where there is no hot water, you should begin by checking that there is power getting to the water heater. Simply checking that the circuit breaker is on and is in working order can save you trouble. A faulty circuit breaker is easy to replace.
Besides the no electric supply problem, there are also other electric problems that may cause a geyser to malfunction. An example is poor contact points, or exposed wires that may result in geyser tripping electricity. Professional geyser installers always make sure there is power isolation to specifically supply geyser for repairs to take place effectively.
Geyser Parts to Check When Geyser Not Heating Properly
There are 2 geyser parts making crucial in the heating function of a geyser.
The heating element and the geyser thermostat are the two parts to check when you do not get hot water, or when the water is not hot enough.
Let us look at a situation when the water is hot but not hot enough. So clearly, geyser is on and receiving power supply, but there is an issue with temperature. In this case, the thermostat temperature setting needs adjustment. The temperature should be set at no less than 50 degrees Celsius.
Secondly, if there is no hot water at all, that could mean a faulty thermostat or a faulty element. Thermostat is a device that keeps the temperature of water inside geyser at a desired level. It does this by cutting off the power supply once the temperature reaches the set level. It also resumes connection once the temperature falls below the set value.
Therefore, if a thermostat completely fails, there is no activating power supply to the element if temperature falls.
Faulty Heating Element
A Heating element is one that gets hot and in turn heats up the water within the tank. Just like an electric kettle with an inbuilt thermostat, the heating element converts electric energy to heat.
If an electric heating element fails, it simply needs replacement. Call for a geyser service provider to assess and determine the cause for your geyser not working properly.
Key factors for Geyser installation service works. Professional geyser installers follow proper steps for the fitting of water heaters, to ensure safe working and use. These are important safety aspects of hot water storage tanks that needs to be considered for proper function. According to the regulations and requirements of SANS 10252-1 and SANS 10254, all mandatory parts must be included.
Geyser installation service providers should include all the mandatory geyser parts when fitting a new geyser or replacing an old water heater.
Temperature And Pressure Valve
The temperature and pressure valve should be fitted and have a pressure rating not exceeding the one in the existing system. The tp valve can have equal pressure rating to the one on the existing system.
Expansion Control Valve
The expansion control valve should be fitted and have a pressure rating not exceeding the one in the existing system. The expansion control valve can have equal pressure rating to the one on the existing system.
Pressure Control Valve
The pressure control valve should be fitted and have a pressure rating not exceeding the one in the existing system. The pressure control valve can have equal pressure rating to the one on the existing system.
A Safe Geyser Installation Service Should Consider the Strength of Support Where it Sits.
Water heaters should sit on a solid structure. The dip tray and water heater, must be placed on
tie beams that are supported on load bearing walls. The spacing of such beams must not be more than 500mm apart.
Drip tray should be professionally installed and have proper discharge pipe for drainage.
installed in the correct manner. The drainpipe should be fitted to allow smooth draining of water away from the building and should be easy to see from outside.
These are fitted on cold water supply as well as hot water disposal pipes.
This will ensure no siphonage of the water heater.
Isolating valve must be installed on the inlet pipe of the pressure control valve.
Blocked sewer lines pose a risk to health. Apart from the bad smell and the ugly site of a blocked drains spilling dirty water outside, there are health issues relating to exposure to sewer drain gases. Health problems common from raw sewerage exposure can come from bacteria or parasites. Clogged sewer drain is a problem that needs no motivation to act on, and drain cleaning specialists are always ready to jump at short notice.
Sewerage pipe systems transfer waste water that collects from sinks, bathrooms and other home appliances. Domestic appliances such as washing machines, dish washers and ice machines for instance, will collect and end up in sewer pipes.
The drainage pipes collecting waste water from all other areas are smaller than the one that collects from toilet. However, drain pipes within a building connect outside the building into one system. Therefore, the sewer drainage pipes outside are wider in diameter than the ones from inside.
How Sewerage Pipes Run
Drain pipes run at slope to enable movement of raw sewerage. The drainage pipe system is therefore not working under pressure except the natural effect of gravity. This means that the system should be free of objects that prevent flow of water. Sanitary pads, hairs, fatty substances and other forms of unwanted solids are the main culprits for a clogged sewerage pipe.
Ideally, sewer pipes should have an inspection point, to allow for drain plumbers to clean out the sewer clog.
For obvious reasons, a sewer line runs underground. Therefore, sewer drain system is one of the most common forms of underground utilities.
PVC is now the most common material in use for sewerage drain pipes. Pipe diameter usually for domestic outside sewer drainage pipes outside the house is 110mm diameter. For sink, bathroom, washing machines and all interior waste water drainage, a 50mm size PVC pipe is used.
Grease, fatty substances, soaps and food particles are common causes for interior drain blockages.
How to Detect Early Warning Signs of Blocked Sewer Lines
Slow draining of toilets and bathroom should not be ignored. They indicate that a drain block is present. Debris can begin to pile up following this, and eventually a full drain block will occur.
Additionally, if you start smelling funny and foul smells then it is time to consider a drain cleaning exercise.
Another common sound is the unmistaken gurling sound that follow after flushing, or when water from a tub is released.
The last thing to confirm a total blockage of sewerage system is a flooding on the outside of the house. At this point, the drain pipe is fully blocked.
Electric Geyser Installation Prices in South Africa
Electric geyser replacements on average cost less than fitting a geyser where no geyser existed before. Geyser installers often charge for supply and installation all inclusive.
Price of fitting a replacement geyser however varies slightly according to brand name, tank size and whether or not other support system needs changing.
It may be necessary to replace shut off valves, dip trays or make small changes to the pipe work if the replacement geyser is not an exact fit.
Connection points to supply water and distribute water may have a small off-set from the previous geyser, but this is a simple matter for plumbers to address.
Additionally, geyser prices also vary slightly according to size and brand choice.
Popular electric geyser brands in South Africa includes Kwikot, Heattech, and Builders geyser. Prices are therefore different since demand for brands is not same. For example, Kwikot geyser installation is slightly higher than builders high pressure geyser fitting.
Electric Geyser Installation Prices for Replacement Geysers
Geyser replacement cost is roughly R7500 all inclusive.
For geyser sizes between 5oliters and 150liters, price is not much different. For instance, a 100liter geyser is not that much different in price with a 150liter geyser. However, as the sizes increases to 200liter and beyond, there is a bigger difference in prices.
Therefore, you need to check what size you want, that will meet your needs.
On average, labour charges for geyser fitting are R2500.
Replacing a water heater is much easier to estimate the price since plumbers make use of existing piping system. This means you can get a price of geyser fitting telephonically, if you know exactly what you want.
Cost Of Installing New Geyser Where There Was No Geyser at All
All things being equal, the cost of installing a geyser from scratch equals the cost of geyser replacement plus additional material for supply and distribution. Such additional material includes dip tray, copper pipes, electrical isolators, shut off valves and any other part that does not come standard when buying a geyser. Basically, all geyser parts that do not come standard when buying a geyser will make a difference on price.
Hence, distance to from the nearest possible water supply, and nearest link to distribute hot water counts.
It is clear that the final quotation for fitting a new geyser from scratch is determined after a site inspection. Also, labour might also be slightly higher depending on additional hours needed to install the support system.
Geyser thermostat data that is just good to know, for consideration when you are not getting hot water from your water heater.
A thermostat is a heat sensor that controls the level of heat in a system. This is made possible by switching a load on or off as the heat levels rises or drops.
These sensors are useful in any systems where one needs to maintain heat levels to a pre-set value.
Heat sensors have a wide range of uses in areas such as heating and cooling systems, central heating systems and many others.
Position of Geyser Thermostat and its Function
For a geyser, the heat sensor does not get in contact with water, therefore it senses the heat levels of the element.
The element is the one that actually gets hot and in turn heats water within the tank.
A water heater thermostat has a head and a rod “tail” attached to the head. The rod fits into a hollow socket of the element, and senses temperature of element.
A desired temperature is pre-set on the thermostat. One the level is reached, the unit cuts off power to the element. Conversely, if the heat level drops below the pre-set level, the sensor will reconnect the element.
When your water is not hot at all, geyser installation and repairs professionals begin by testing if geyser thermostat is in working order. If this sensor fails, it means it ceases to sense anything and therefore can not trigger the element to heat up or to stop supply heating.
How To Adjust Thermostat Settings
First, ensure power supply is cut off as a safety measure for geyser maintenance.
Then locate and remove the protective cover, also known as a geyser gasket. The gasket can be easily taken out by turning screws with a flat screw driver.
In modern heat sensors, the adjusting lever is out in the open, so all one has to do is turn it to the temperature of choice. There are marks around the head of the sensor and the lever has to point to the desired value. It is important to use the correct range of geyser thermostat temperature. Correct thermostat setting ensures safety as well as best energy use. Ideally, temperature should range between 50 degrees and not more than 70 degrees.
No hot water is the most common sign of a faulty thermostat. However, a faulty sensor is not the only cause of no hot water. If you are not sure about a faulty geyser, call your local plumbers for help.
Causes of leaky pipes range from poor plumbing installations, wear and tear to pressure and environmental effect.
There are different methods of fixing leaking pipes according to pipe material, but now we only look at the causes.
High water pressure – although it is rare to occur in South Africa, it sometimes happens that you can experience an influx of water pressure. Municipalities in South Africa make a point to monitor water usage strictly due to water shortages in the country, therefore it is not common for high water pressure influx. However, in those rare moments, plumbing pipes may get damaged, resulting in water leaks.
An easy solution is to have a pressure reducing valve fitting within your system. Your local plumber can fit in a pressure reducing valve and set it to the correct value.
Additionally, it is always important that after any plumbing repairs are done where water was temporarily cut off, you open faucets and let air out. This is especially true for repairs on main lines, as there is a tendency of air getting trapped in the lines, thereby inducing additional pressure to the system. The induced pressure is a hazard to plumbing pipes as well as faucets.
Causes Of Leaky Pipes in Drain Lines
Effect of tree roots – tree roots close to water supply line or water disposal lines may cause a weakness to pipe joints. Especially drain lines that dispose water from bathrooms, toilets, and kitchens into the sewer lines. Roots find their way inside the pipes, causing leaks and drain blockages.
Blocked drain lines.
Drain clogs can results in pipes getting burst or leaks on joints. Therefore, it is important to call drain cleaning service providers early and not ignore even a slow drain block.
Leaking Pipes in Galvanized Pipe Systems
Although less common these days, old houses still have galvanized plumbing pipes. These pipes are prone to corrosion, a reason why they are no longer popular. Leaking pipe joints may result from corrosion, as rust eats away the pipe at joints. Furthermore, rust built up may cause blockages and weaken the pipes.
Sudden rise or drop of temperature may cause cracks in water pipes that will eventually result in leaks.
As your plumbing system ages, rust and other forms of corrosion may eat away at the pipes.
Wear and Tear
Over time, the pipe fittings at joints become weaker due to aging. Small movements on pipe joints may result, causing water leakages.
Poor laying of pipes as well as poor joint fitting can be a cause of leaky pipes. Over time, a poorly connected joint will give in. Making use of reputable plumbing companies is recommended.
These are but some of the causes of leaking pipe in buildings
A friend of mine was complaining about huge water bills for many months. At first, he thought the water meter was faulty, so he requested the Johannesburg Municipality to get it checked. However, that request was taking edges to be attended to. Since it is illegal to replace Municipal meters, he was stuck for many months. He was paying up to 5 times the normal bill. I advised him to run a simple test from the water mains to check if there is a leak which he did and confirmed a leak. He later hired leak detectors to locate the source, which they found under concrete paving. No wonder why it was not visible to the eye, no wet patches could be seen on surface. He managed to replace the leaking pipes portion at about 30% of what he already paid for in excess amounts of monthly water bills. Imagine how much he would have spent over a year!
Leakages of water can be very costly in terms of monthly bills and property damage. In addition, the structure as a whole can lose its strength over time. Ceilings and masonry can be damaged especially if the leak is emanating from a hidden point and goes unnoticed for a long time.
Thankfully, if you notice high water bills you can do this simple test to determine if indeed there is a leak arising from plumbing.
Simple test to determine presence of water leaks on plumbing systems.
To determine if leaks are present, take 3 easy steps
- Shut off all faucets in the building
- Check for movement on the water meter reading
- If the water meter keeps moving after shutting off the faucets, it is a sign that water is leaking somewhere.
Some leaks however, may not arise from plumbing systems. Such leakages may arise from faulty gutters and roof tiles for example. Especially if you notice wet ceilings and masonry after or during rain. In the case of roof tiles, if you access the ceiling during the day, you will be able to identify areas where light is getting in and can easily have that repaired.
Regular cleaning of gutters will save you from blockages, that may also result in water seeping through and running into unwanted spaces.
Factors affecting performance of plumbing systems
Factors that may cause plumbing systems to give in include rapid temperature changes, worn out gaskets and rubber seals. Additionally, poor plumbing may result in leaks
Further, the problem area may be far from the visible mark seen on wall or ceiling. This is so because water tends to trickle to the weaker point.
For galvanized pipes, hard water may corrode pipes leading to blocks and pipe damage.
What are the areas to look out for Water Leaks?
Water leakages in Ceilings
Looking at the sources of water leaks, one can see that both plumbing problems and roof problems can result in damage of ceiling. The common noticeable signals for leaks above ceiling are sagging, discolouration and paint peeling off the ceiling. Further, water droplets can also be visible, posing a hazard of slipping as water forms on the floor. If the ceiling is a concrete slab, where plumbing amenities are present on the building above, leaks from bathroom can find their way downward as well. Sometimes, a wall can be the path of least resistance for water, such that water may seep through from above ceiling into the walls.
If clear water is leaking from ceiling, it is usually a sign of a plumbing problem from the water supply lines. Particularly if the leak is constant through out the day. Leaks caused by roof
Plumbing leakages from drain lines
If you notice that the leak only occurs after using plumbing amenities, such as flushing toilet, washing hands on a basin or after showering, it means the issue is on drainage systems. You only have to assess the plumbing of the facility in question, and f
Leaks on Walls and Underground Pipes
Poor plumbing workmanship may cause leaks walls.
The signs to look out for include peeling paint, discolouration, patches or smell from within doors.
You may notice that floors always wet at a certain area or carpet. Most common areas to check are near amenities like washing machine, toilet, sink etc.
Prolonged leaks may result in mould formation on walls.
Underground water leaks
Water leaks are usually easy to fix if the leak is on surface, because it is much easier to locate and to trace the source of the problem.
Water leaking from buried pipes or embedded pipes can go unnoticed for days or months depending of the source of leakage. This is particularly true for underground leaks, as elements above pipes may hinder one to identify wet spots.
The situation can get to a point where one sees moulds on the walls or paint peeling off.
Plumbing companies provide plumbing maintenance services, installation, and repair services to different types of businesses.
Additionally, plumbers respond unplanned calls for emergency plumbing repairs such as water leaks and drain blocks.
Typical clients are property management firms and realtors, individual homeowners, and tenants as well as businesses and government departments.
Plumbers are almost always on the move, from place to place attending various plumbing requests. Therefore, plumbing firms and freelance plumbers spend time and money in vehicle maintenance, buying tools and equipment as well as on insurance.
The plumbing industry has a lot of players, such that to stay in business, a good marketing strategy is necessary. Most well-known plumbing firms rely on social media adverts, online marketing as well as word of mouth to stay in the limelight. Like other handymen companies, plumbers also partner with other tradesmen to expand their presence and tap into new clients.
Occupational Heath and Plumbing Work
One of the concerns for most plumbing firms is to keep high safety standards and do way with or limit the risks relating to wok. Health hazards that may affect the plumbers include asbestos related illnesses such as inflammation and scarring. Also, plumbers work in confined spaces as well, so the workforce should be competent to work in such environments.
What is The Common Piping Material Trusted by Most Plumbing Companies?
Copper pipes form one of the most versatile plumbing materials in use for pipework today, due to its qualities of strength, flexibility, and ease of use. However, different situations require different pipes according to function.
Copper plumbing – Good for water supply especially in houses and offices. There is rigid copper and flexible copper, each one with different function. Rigid copper can be cut and soldered and is good for housing use.
Flexible copper is particularly useful for small areas where the working space is such that flexibility is more important to allow work in tight spaces.
Galvanized plumbing, Galvanized pipes are no longer famous, but are still found in old houses and other non-potable water distribution systems.
High density polyethylene (HDPE) – Good for irrigation, pool piping and other water transfer systems. They are stiffer and harder than LDPE and therefore a higher resistance to high heat levels. Additionally, they can also withstand the effect of certain chemical agents.
Like copper, HDPE is a very versatile plastic material for use in plumbing.
Common Causes Of blocked drain In South Africa
Here are the most common causes of blocked drains:
Tree roots are the most stubborn cause of clogged sewer drains especially in wooded areas.
The roots can find their way into the drainage piping systems.
Normally, specialists are required to clean a drain clogged by roots, as they employ drain machines.
Roots trap tissues and other objects within the drainage system and this results in blockages
Tissues and Wipes
Some washable bathroom wipes can also result in drain blockages
Only biodegradable matter is easily processed by plumbing waste systems, so any type of harder tissue or paper may have a negative impact on the system. Tampons and sanitary pads are often found in the drainage systems and this is not supposed to be so. Some residents flush tampon in the toilet and this is not recommended
Other Commonly Ignored Causes Of Blocked Drain
Fat, oil and grease
These are common causes especially for sink drains. Fat from various oils are not welcome as they are sticky and tend to solidify and accumulate and trap other matter. Examples are bacon grease and fatty foods
Hair & Toiletry
Loose air can find its way on the pipes and accumulate on bends, causing blockages particularly in basins and showers. Pieces of bar soap can also potentially block a toilet
It is important to have regular maintenance of the plumbing system to address matters before hand, be it blocked drains or leakages.
Poor plumbing workmanship
Poor plumbing such as a piping system that does not slope well can cause blockages.Usually the pipe will bend at a point alone the system due to the weight of water and debris stuck at a single place.
Things to avoid in the drainage system
Meat, skin and bones
If all fails, or you are not keen on self help exercise, consider drain cleaning specialists in Gauteng.
