- Before you start working on your gas water heater, clear the area around the heater. Remove all the clutter and move the items lying around the heater.
- Locate the water heater gas valve. It is located towards the bottom of the water heater just above the burner chamber.
- You will see three main settings on the valve - 'OFF', 'Pilot' and 'ON'. Turn the dial to ‘Pilot’ setting. shut the gas off to the burner without shutting off the pilot light.
- Now locate the gas shut-off valve. Look above, to the side or behind the water heater for the valve. If you are unable to find the valve, follow the gas line that extends from the water heater. You will find the shut-off valve at the end of the gas line.
- Some valves have a handle while some have a knob. Turn the handle or the knob until it stops. If you have a handle on your valve, you will notice that the handle is now at the 90° to the gas line.
- Now turn off the water supply to the water heater.
- Wait for some time to let water inside the tank to cool down.
- After 15-20 minutes, drain the water heater. Attach a garden hose to the drain valve at the bottom of the tank and empty the tank fully.
- Loosen the screws on the access panel at the bottom of the water heater, and remove the plastic cover of the panel. Remove the insulation and look inside the water heater.
- Make sure you don’t see any blue flame, verifying that the gas supply to the water heater has been disabled.
Gas water heaters have been more popular as they provide hot water usually twice as fast as storage and electric water heaters. Not only this, gas water heaters continue providing hot water even during power-cuts. But, these water heaters don't stay effective and function at their best throughout their shelf lives. Just like other types of water heaters, gas water heaters can stop providing enough hot water, can start leaking from various places, and can make unusual sounds while in use. To find out the actual cause of these water heater defects, it is important to turn off the gas supply, switch off the heater mechanism, and check what's wrong. Turning gas and water supply to the heater will ensure that no harm or mishap takes place during the inspection. It is very easy to turn off the gas supply to the water heater but often many homeowners don't know how to do so. In this article, we have explained the step-by-step method to turn off the gas supply and completely shut down the gas water heater.
Until it stops working or is suddenly facing a serious issue, we all tend to ignore our water heaters. But, what can be worse than too cold or scalding hot water from your water heater? No other defect, I am sure! Even after proper hot water tank installation, after a few years, your water heater can stop giving hot water. Too cold water can result in bacteria growth in water while hot water is harmful in several ways. So what is the ideal water heater temperature? You must set your water heater at 120°-140° for comfortable water use. This ideal water heater temperature helps in controlling the overall utility bills of your house and also increases the efficiency of the heater. Let’s look at how you can set the ideal water heater temperature on your own.
Have you been noticing a pool of water under your hot water tank? If yes, then maybe it's time you get serious about your often ignored hot water tank. If you hear a dripping sound from the tank or notice a pool of water more than often, you must immediately fix the problem in order to avoid major and costly repairs. For fixing water leaking from the tank, you must first identify its source and what is causing the leak Below are some common reasons why a hot water tank leaks.
Loose Cold Water Inlet and Hot Water Outlet Connections
The cold water inlet and hot water outlet pipes are connected at the top of the hot water tank. Loose connections of these pipes can lead to minor leaks. If not fixed, the leaks can eventually create a pool of water on the top surface of the tank and droplets may even trickle along the tank surface. Simply tightening these pipes also works.
If you notice a pool of water when the tank is first filled or during winters, you probably don’t have leaks but condensation issue. This is normal. Normal condensation from the tank pipes or a nearby appliance can lead to a small pool of water around the base of the tank. In many cases, condensation forms when cold water fills the tank.
Faulty or Broken TPR Valve
The temperature pressure relief valve is useful in eliminating excessive pressure from the tank when water gets too hot inside the tank and in keeping the tank safe. A small tube runs from the valve to the floor to direct the leakage downwards. If the TPR valve is faulty or broken, you will notice leaks from this small tube downwards.
Leaking Drain Valve
Every hot water tank is equipped with a drain valve at the bottom of the tank that is used to drain and flush the tank. A loosely secured or broken drain valve can result in leaks from the bottom of the tank. You can easily replace the drain valve to stop the leaks.
If you don't drain and flush your hot water tank regularly, or carry out water heater tank maintenance, sediments and minerals may start getting deposited at the bottom of the tank. These buildups can result in internal corrosion of the tank. The corrosion can eventually lead to cracks or pinholes in the tank. Once a minor leak starts through the cracks or holes, the pressure of water can force it to make its way and result in leaks.
Most of these hot water tank defects can develop over the years or may occur due to poor installation of the tank. In either case, you must contact our Edmonton water heater installers to keep your tank efficient and long lasting.
