Noisy Water Heater? Sediment Might Be to Blame

Does your water heater sound a little strange? Several noises can come from this frequently used appliance, including screaming and screeching, rattling. But if you are experiencing a popping or knocking noise, you likely have a sediment build-up in your tank. 

Noisy Water Heater? Sediment Might Be to Blame

Traditional tank water heaters should be drained and flushed every year to prevent sediment build-up from accumulating. If it has been a while since you’ve performed routine maintenance on your water heater or if you have hard water in your home, sediment can hurt the unit’s performance or shorten its service life.

How to remove sediment from a water heater tank

To fix this problem and get rid of the popping and knocking noises, you will need to perform a proper flush of the tank. Here are the basic steps.

  1. Turn off the water heater. 
  2. Turn the cold water supply valve off.
  3. Let the water within the tank cool to prevent burns. 
  4. Attach a hose to the drain valve (located on the side of the tank). 
  5. Place the end of the hose in a drain or large bucket (such as a stationary tub). 
  6. Turn on a few faucets in your home. This prevents a vacuum from forming in your pipes.
  7. Turn the drain valve on and drain the tank. (You will need a screwdriver for this step.)
  8. Once the tank is fully drained, turn the cold water and water heater back on. 

Warnings while draining the tank

Like most DIY plumbing projects, it’s important to use extreme caution when dealing with a hot water tank. Failing to follow the instructions on your specific tank and standard safety protocol could result in significant health hazards. Always consult with a professional if you do not feel prepared to safely execute the task at hand! 

Why is sediment build-up necessary to remove? 

Sediment build-up is natural in tank water heaters and might not be a big problem at first. But over time, residue and sediment build-up can lead to your water heater failing to heat efficiently, and can even cause the unit to overheat, resulting in irreparable damage to the water tank’s protective liner.
