How to Drain a Hot Water Heater


 If you are wondering how to drain a hot water heater then you are at right place. 

Draining a hot water heater is vital for the removal of buildup and making sure it performs efficiently. Below is a step-by-step guide for drain a hot water heater.

1. Do a Quick Flush

  • Turn the power off if you are using an electric heater so that you avoid shocking yourself.
  • If it is a gas water heater, flip the switch to “Pilot” to avoid gas leakage.
  • Look for a valve at the top of the water heater.
  • Turn off the water valve.
  • If you can’t see the valve, check the heater’s user manual.
  • Connect a garden hose to the drainage valve, located at the water heater’s base.
  • To connect, line up the hose with the drain valve threads.
  • Attach the hose firmly to prevent water from leaking out.
  • Put the other end of the hose lower than the drain level for water to flow out.
  • Place the garden hose outside for the water to run off securely.
  • You can check for heater damage or sediments by running the water into a bucket.

2. Unfasten the Drain Valve

Look for a level or knob on the water heater and turn it to open the valve. If it is hard to turn, use a wrench or screwdriver. Ensure you open the valve fully. Next, pull the pressure relief valve to allow air to flow through and discharge the water. If the water refuses to drain immediately, unlatch the nut on the heater to allow air to move through. Make sure you don’t remove the nut altogether. Allow the water to drain completely, and then run clean water through the heater to remove all sediments from the bottom. Let the water flow for five minutes, then switch it off.

3. Switch the Heater Back On

Turn off both the drain and pressure relief valves and ensure they’re completely closed. Next, detach the hose from the drain valve and dump any water inside it to prevent damage.

Turn the power back on if you’re using an electric heater. If it’s a gas heater, turn the pilot switch to “On.” Inspect the drain valve for leaking.
