A Guide to Flushing Your Water Heater: Expert Advice

August 19, 2023 Author: Bekhruz Nagzibekov

At United Plumbing, we understand the importance of maintaining your home’s plumbing system for optimal performance. One essential, yet often overlooked, aspect of home maintenance is flushing your water heater. In this comprehensive guide, we share step-by-step instructions on how to flush your water heater to ensure it runs efficiently and lasts longer.

Understanding the Importance of Flushing Your Water Heater

Regularly flushing your water heater can significantly enhance its lifespan and efficiency. Over time, minerals and sediments in the water accumulate at the bottom of the heater, leading to:

  • Reduced Efficiency: The sediment layer causes the water heater to work harder, increasing energy consumption.
  • Corrosion: The accumulated minerals can cause corrosion, leading to leaks and potentially costly repairs.
  • Noise: You might hear a rumbling sound from your heater due to water bubbles escaping through the sediment layer.

Steps to Flush Your Water Heater

Before you start, ensure you have a garden hose, a pair of gloves, and protective goggles. It’s a relatively simple process, but if you’re uncomfortable doing it yourself, United Plumbing’s team in Sunnyvale is always here to help.

Step 1: Turn off the Water Heater

If you have a gas water heater, turn off the gas supply. For an electric heater, switch it off at the main power supply.

Step 2: Connect the Hose

Connect your garden hose to the drain valve located at the bottom of the water heater. Make sure the other end of the hose is in a safe location where the hot water can be drained, such as a garden or a floor drain.

Connect the Hose

Step 3: Drain the Water Heater

Open the drain valve and allow the water to flow out of the water heater. Be cautious, as the water will be hot. For safety reasons, keep children and pets away during this process.

Step 4: Flush the Heater

After draining the heater, open the cold water supply valve for a few minutes to flush out any remaining sediment. Repeat this process until the water running out of the hose is clear.

Step 5: Refill the Heater

Close the drain valve, disconnect the hose, and turn the cold water supply on to refill the tank. Once full, turn the power or gas supply back on.

When to Flush Your Water Heater

The frequency of flushing your water heater depends on the water hardness in your area. For areas with hard water, we recommend flushing it at least once a year. For other areas, every two to three years is sufficient.

We recently hired United Plumbing to replace our old HVAC system. From start to finish, the experience was exceptional. Their technician, Oleg, thoroughly inspected our attic and crawl space to accurately assess our needs. The estimator, Fariza, provided a clear and competitive quote based on Steve's findings. The installation team, Oleg and Valerii, were true professionals. They were courteous, efficient, and meticulous in their work. The quality of their installation was outstanding. We were highly impressed with United Plumbing’s professionalism, responsiveness, and fair pricing. We would highly recommend them to anyone looking for a reliable and trustworthy HVAC company.

Victor showed up quicker than any other technician from any company could during a AC malfunction during a heat wave. He was thorough and fixed the main and secondary issues. Great job.

Semenov was knowledgeable and straightforward with descaling my tankless water heater. Didn’t try to upcharge me. $130 cost for descaling, same as buying the tools. Good value.

Super fast to respond to my request and very easy to communicate with. Alex was prompt, professional and friendly and didn’t make me feel bad that I had a very simple job I probably could have figured out myself. Great service. I’ll be back.

This was the 3rd company I looked into for my plumbing issues. I was able to get a same day appointment and the technician Almaz arrived at the start of the 2-hour window they quoted. I even got a text that he was on his way. I had two pipe leaks, one under the bathroom sink and one in the crawl space. Almaz was careful and thorough in diagnosing the latter and worked his way down the tight crawl area. We ended up cutting out dry wall in my garage to get an actual quote. Their prices seem very fair and so far I’m very happy I went with them. Will update once the fix is complete.
