How to replace a drain valve easy and fast

There are 2 types of drain valves that are largely found on electric water heaters and tank-type gas heaters, made of brass and plastic. A powerful and more strong is better, the advice is to purchase a water heater that is packed with the brass drain control device, while the plastic drain valve are simple to damage mainly around the threads making them more likely to leak. If the water heater has the plastic control device already built-in, you might want to change it with the brass valve.Image result for Pressure Ball Valves

Some plumbers advise using the high pressure ball valves as there are bigger and better for successful and quick drainage and provide problem-free maintenance.

Why draining

There are several reasons why to drain a water heater:

  • Changing a heater or component parts that need emptying the unit.
  • Winterizing, prepare your heater for chill months by draining the tank.
  • The drain plug is blocked
  • Water heater drain control device leaks
  • The drain valve is destroyed

Changing a drain valve on gas and electric heaters is very simple and it does not need any unique tools or expertise. It is vital to have the water within the tank cooled off. To change the part you can either partially or fully drain the water from the tank. The reasons for changing the valve might be clogged, leaking or broken valve.

  • Turn the energy off at the circuit tidal wave if the heater is electric or start the gas control device to pilot if you have a gas piece.
  • Shut the big water supply control device placed close to the heater. Ensure all the faucets in the house are closed as the vacuum created within the tank will stop water from running out and make the issue.
  • Prepare the new drain control device by applying the pipe sealer or Teflon tape to the valve threads. If the water heater comes with the plastic control device, change it with the high pressure ball valve or brass valve.
  • Put the bucket below the control device to get the exiting water.
  • Unscrew the old water heater drain control device by using the adjustable wrench or big groove-joint pliers.
  • Due to the buildup force within the tank, you might have a rush of liquid once you get rid of the old valve.
  • Quickly install the new high pressure ball valve, turning it clockwise so the heater would not lose too much liquid.
