Water is an essential element that everyone needs in their daily life, and its uses are unlimited. But in winter, the water needs to be hot to be used as it is quite difficult to use cold water in such weather. Thus, water heaters are used to heat water, as hot water has many health benefits.
When you use a water heater for some time, some of the particles present in water start settling down in pipes and affect the performance of the water heater and its flow. If this problem is not fixed early, it can lead to the failure of the water heater.
To eliminate the sediments or particles that gather in pipes, draining of the water heater is used. It is an easy and simple process that anyone can perform with the help of some tools if they follow the steps given below.
Steps to Drain a Water Heater
Any task is difficult to perform if you don’t have the proper set of tools. In this case, the number of tools is very limited and can easily be found in almost every home. They are:
- Water Hose.
- Screw Driver.
Turning off Water Supply
To turn off the water supply the first thing a person needs to do is turn the cold-water supply off that is being placed at the top of the body of the water heater, so the process of drainage is easy, and no disturbance takes place.
Turning off Water Heater
Now, to turn the water heater off, you may shut the power off at the breaker box or transfer the thermostat to the pilot mode settings. Turning the power off in the breaker box is very important as some of the water heaters are directly connected to the circuit breakers, and this may be dangerous and risky that the current can pass through. The electric water heaters may be very hot even after being turned off. So, a person shall wait for one night to let the water cool before draining the water out of it, or else it may cause a problem or damage in many ways.
Attaching Hose to Drain Valve
To attach a hose to the drain valve, a person should attach a garden hose to the valve provided for drainage purposes. It is placed at the posterior end of the tank in most of the models, but some may have a protective plastic cover or structure at the drainage valve’s opening point. So, remove the cover, if there is any, to attach the hose. Now the other head of the hose is to be attached to the floor drain pipe for a perfect and safe drain. In this process, a person shall be very careful and should handle the hot water with care. So, there is no risk of being burnt by the boiling hot water.
Opening a Hot Water Tap
To increase the pressure of the water in this system, open up the hot water tap or shower that is near to the water heater. This will allow the water to drain out fast from the water heater tank directly. The tap away from the water heating tank will take a bit of time to drain the hot water, but the near one will drain water quickly out of the tank. It will be even better if that tap is at an upper portion, which helps in creating more pressure.
Opening Drain Valve
The flow of water may be interrupted by the accumulates or deposits at the opening part of the drain valve. So, to remove the residue and to make the water flow without any interruption, open up the drain valve and let the water go out of the water heating tank. When all the water is being removed from the tank, let the tank be filled with the cold water to remove the accumulates and do so until the water goes clear without any pollutants and residues. As the water is highly hot, you will have to be very careful about handling the hot water, so you don’t get burnt. If for some reason, the residue blocks the pipe and doesn’t let the water pass, then, unfortunately, professional help will be needed as a normal person can damage the heater if he tries to fit it.
Refilling of the Water Heater
To refill the water heater tank, you will have to close the valve for the drain and then remove the drain hose. The next necessary step is to join a source of water or a pipe and keep it fastened over the water heater tank. Then, turn the water source ON, and now you can let the water be filled into the water heater tank. Now, turn on any tap or shower and let it run until the water comes out of it flawlessly without any gap or air-break.
Relighting the Water Heater
In the case of an electric water heater tank, one will have to turn the power back on to relight the water heater tank. And if it is a gas water heater tank then turn it to the pilot mode. When the heater is turned on, wait for some time and check if it is heating water by turning one of the taps ON.
Checking the Drain Valve
After you have done all of the above steps, one final step is to check if you have properly closed the drain valve so that it doesn’t leak. If it is leaking, try to tighten it up till the leakage stops. Sometimes the valve becomes free and doesn’t fit completely; then you will need to change it.
There are certain things that you should take precautions from as it can be harmful to you. The precautionary measures are given below:
- If you have an electric water heater, you should disconnect the heater from its power source as it can be dangerous and, in some scenarios, even fatal, if current makes way to you.
- If you have a gas water heater, turn off the gas valve connected to the heater to prevent any mishap.
- When draining the water from the water heater, handle it with care as the water inside it can be hot, which can burn you. Also, parts of the heater can be hot enough to damage you.
- When done with draining the water heater, check all the connections thoroughly. If somehow a valve leaks, that can cause trouble later.
So, if you follow the above steps up to now, you should be able to drain your water heater with ease. Keep in mind the precautions because ignoring them can cause you trouble. If for some reason, you are not feeling confident enough to drain the water heater by yourself, you should seek professional help from a technician.
