What is a Drain Valve In Water Heater

water heater drain valve

A water heater drain valve is a compact valve fixed at the rear of the heater built to drain water from the heater’s tank for rinsing and upkeep purposes.

It is fixed on both electric and gas models; it has two strung ends (standard size of ¾”), one to tighten it into the heater and the second to connect the garden hose (for draining). The valves can be with the handgrip hold or screw head to free or tight.

Choosing the Right Drain Valve Replacement

There are three significant kinds of drain valves designed for gas and electric water heaters, namely: plastic, composite, and brass.

As noted above, there are built-in plastic valves in most water heaters, however, by using brass/composite valves alternatives you can always replace them.

  1. Plastic valves are inexpensive but not relatively as durable as the two alternatives. Since they are prone to damage easily, the valves are more probable to seep.
  2. Composite (glass-filled nylon) valves do not weaken the unit anode as brass valves do. They are also moderately cost-effective.
  3. Brass valves continue to be a promising choice for water heaters. Not only are they popular for reliability, but they can also resist the increased temperatures glimpsed in high-temperature facilities.

Hot Water Heater Drain Valve Replacement Steps

Drain valve repair

Renewing a drain valve on electric and gas heaters is very simple, and it doesn’t need any specific equipment or mastery. It is essential to keep the water inside the tank chilled out. To restore the portion, you can either wholly or partly deplete the water from the tank. The purposes for renewing the valve might be seeping, blocked, or wrecked.

  • Turn off power at the circuit breaker in the electric heater. If you have had a heater, turn the gas valve to the pilot.
  • Shut off the main water supply valve placed close to the heater.
  • Ensure that you close all the faucets in the house, as the vacuum built inside the tank will stop water from running out and result in damage.
  • Ready the new drain valve by applying the pipe sealer or pipe sealer to the valve cords. If the water heater is with a plastic valve, replace it with a ball or brass valve.
  • Keep the bucket under the valve for the collection of the existing water.
  • With the help of large groove-joint pliers, adjustable wrench, or unscrew the old water heater drain valve.
  • Due to the pressure that builds up inside the tank, you may have a wave of water when you eliminate the old valve.
  • Hence, rapidly induct the new valve and turn it in a clockwise direction so the heater will not lose plenty of water.
  • Switch on the power to the heater again, including the supply of gas. If the gas water heater possesses a pilot light, you may need to relight it following the guideline found on the sticker.
