Why is draining your water heater important?

Periodically draining your water heater matters because it:

• Removes sediment buildup in your water system
• Improves the efficiency and lifespan of your water heater
• Proactively diagnoses issues like loud noises and less hot water

While homeowners can perform basic draining, it is recommended that for more comprehensive water heater treatment, you call in the professionals.

What are the signs I need to drain my water heater?

As a homeowner, these are the signs you may need to drain your water heater:

• Popping or rumbling noises
• Inconsistent or less hot water than normal
• Cloudy or rust-colored water

Additionally, if you are not experienced these signs but your water heater hasn’t been flushed in more than a year, it may be wise to proactively flush it before the symptoms begin popping up.

What to avoid when draining your water heater

Here are the common mistakes to avoid when flushing your water heater:

• Remember to turn off the power so as not to damage the heating elements
• Don’t forget to open a faucet when draining
• Don’t use an old or clogged drain valve
• Check for leaks after you’ve refilled the water heater
• Do not attempt to drain a heavily corroded or leaking tank

When and why to call a professional plumber for your water heater

If your drain valve won’t open or is leaking and no water is draining then there could be a possible blockage which would necessitate a call to a professional plumber. Also, if the water remains dirty or rust-colored after flushing and/or if there are signs of corrosion or tank failure, you should pick up the phone and call the professionals.

A professional plumber can provide a thorough system inspection, identify hidden issues, safely handle older or failing units, and ultimately extend the lifespan of your water heater.
