How to Unclog a Drain Valve?
Clearing the water clog means that you need to get from the basics. But before that, you need to understand how serious the levels of the clog are. There are many ways by which you can unclog the water and this will determine how serious the clog is.
You can try out the list of methods as mentioned below starting from the easiest at the beginning to the most complex steps. But before you get started, make sure that you follow the safety precautions first.
1. Give it Time
If you have minor clogs in your geyser, try to give some time. If you are staying in a contaminated area, it means that minor rusts will always form. But you may not have to worry about it much.
You can simply apply some nominal pressure which will allow the clog to flow out of the drain valve. However, you can easily follow these simple steps to get effective results.
- The first thing that you need to do is to attach a garden hose to the drain valve. You can now run the other end of the outside or to an indoor drain. This will allow the water heater to build pressure.
- The next thing that you need to do is to close all the hot water faucets and then open the drain valve.
- The pressure will allow the clog to move out of the pipe and push through the debris. You can just give a couple of hours for this process to completely clean the clog.
2. Stiff Wire
This method is very effective if there is not only a clog but a small amount of debris present in the tank. The debris blocks the outflow of the tank from draining. In fact, you can also hear some odd noises because of this process. However, to know more, you can simply follow these steps:
- The first step is to close the drain valve and then get the hose disconnected. You can place a small tub or a towel just below the drain valve. This will help you to catch the water from the valve.
- The next step is to open the drain valve and then use a stiff wire or a wire coat hanger to the opening mouth of this valve. Now try to gently rotate the wire in a circular motion.
- If you have done it properly, the water will start flowing through the valve immediately. However, if it is not done, you need to continue the process until the water flows out.
- Once the water flows out, you need to turn off the valve and connect the hose. This means that your heater is now ready for use.
3. Stomp the Hose
If you feel that the above two methods are not working, you can try out the Stomp the Hose method. Here are the steps that you need to fulfill.
- Keep the hose attached to the valve and leave the valve open. This will allow the water to stomp on the hose. You need to increase the range to 2 feet from the water heater.
- This means that an air bubble will come into the water heater. This may be just enough for you to unclog the drain.
- Because of the pressure, the clog will automatically flow out to the drain pipe. If it does not flow out, you need to settle the clogged valve again.
4. Reverse Flow
The Reverse Flow method is one of the most unique ways of cleaning the clog from the water heater. This process mainly works when the drain valve is completely clogged and it is not working at all. Follow these steps:
- Keep the drain valve closed and then connect one end of a different hose tot the drain valve and the other end to the garden hose.
- Turn on the water to the faucet for about 10 to 15 seconds which will give you great results.
- Allow the water to flow to the valve and it will easily unclog the drain valve at no time. Once it is done, simply disconnect the hose and allow the water to drain. This will also remove the clog if it is not much severe.
5. Replace the Drain Valve
If you are unable to manually remove the clog, you can easily try the option to replace the drain valve. Follow the steps below to know more.
- Wrap up the threads of the new brass drain valve with the help of Teflon Tape. Make sure that all the hot water faucets are closed and the heater is powered off.
- This will create a vacuum which will prevent the water from pouring out. You can place a towel or a pan to collect the water under the drain valve.
- Use an adjustable wrench and unscrew the old drain valve. Try to quickly replace with the new drain valve during this process.
- Connect the valve with a garden hose which will allow you to get a proper result.
6. Replace with a Ball Valve
Just like the drain valve is important, the ball valve is also important for any water heater. Because of the mechanism, the drain valve tends to clog faster than any ball valve. So you can easily replace the drain valve with a ball valve. Here are the steps to follow:
- Take the ball valve and wrap up both ends with a Teflon tape. You need to screw one of the wrapped ends of the valve to the dielectric nipple.
- Wrap up both the ends of the other nipple with the same Teflon Tape. Make sure that you allow a space for the handle to move. The handle should move away from the tank.
- All the faucets in the home should be closed to prevent the water from pouring out of the valve. Now you need to connect a garden hose with the ball valve to drain the tank.
7. Move Your Tank
Sometimes, when innovative ways are not working, try to use the traditional way of moving or shaking the tank. Here are the steps to follow.
- Disconnect all the power sources of the water heater and also all the incoming and outgoing water pipes.
- Pull out the water heater from the wall and start shaking the heater gently. Rock it onto a hand truck and roll it outside.
- Once you are done, attach it back to the initial position. Simply open the drain valve to let the water flow out of the tank. This will clear the clog.
