Replace a Leaking Water Heater Drain Valve


If your water heater is leaking, you may be quick to call in a repair man to fix the problem. However, before you call in reinforcements, consider learning how to fix the problem yourself.

Why Fix It on Your Own

Water heaters that leak are not a new thing or a rare thing. In fact, they leak quite often so instead of letting the maintenance bills pile up, learn how to do it yourself so that when it happens again it will be a quick and easy, and still cheap fix. You will be surprised how simple it is and there is basically no risk involved. Many people see the tankless water heater reviews and think it is time to switch but it is completely unnecessary, and those systems are expensive. People are also afraid of doing their own home maintenance because they are worried about causing worse problems if they mess up that if you mess this up, not much happens. It will probably just keep leaking, and you will have to try again. No big deal.

Patching a Water Heater Drain Valve

When you drain your water heater, often the valve will start to leak- it’s just how things go. They are used so little that this just tends to happen when they are old or not used frequently. If there is not a significant amount of damage, you can get away with simply patching it up. All you need to do in order to patch it is to use a hose cap on it to keep it from leaking. A hose cap is easy to find at your local plumbing and home maintenance and hardware store, just talk to a sales associate there if you have trouble finding it. More details here.

Replacing a Water Heater Drain Valve

When the damage is significant from your water heater leaking you will need to replace the valve completely. Or even if you are not one to just patch something up, and you would rather have a more lasting fix, replacing it is the way to go.

  • First, make sure you drain the water heater, so it is completely empty. It is hard to work on the valve when there is a constant leak going on.
  • Second, unscrew the old leaky drain valve that has temporarily ruined your life. If it is stuck on tight, use a pipe wrench or pliers to assist in the unscrewing process- you will want to turn it counter-clockwise, or it won’t be going anywhere.
  • Third, check out the length of the drain valve and match your new one to its specifications. The best thing to replace it with is a full port ball valve because it works a lot faster and will last a lot longer.
  • Fourth, use Teflon tape on the threads of the valve you are installing in order to prevent future leaks.
  • Fifth, make sure that your new valve is on tight and facing the correct direction.
  • Sixth, fill up your water heater again and make sure that it does not continue to leak. Make sure to keep checking on it for a few weeks in order to make sure that it is a lasting fix.
