A Guide to Flushing Your Water Heater: Expert Advice

August 19, 2023

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.

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.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.

United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
