Top Water Heater Maintenance Tips for Long-lasting Efficiency


water heater


Your water heater is one of the most essential components of your home’s plumbing system. It works tirelessly to provide hot water for showers, washing dishes, laundry, and many other daily tasks. But, like all appliances, water heaters require regular maintenance to ensure they remain efficient and long-lasting. Many homeowners often overlook this, leading to a decline in their water heater’s performance and, in some cases, a premature breakdown.

At New Pro Plumbing, we understand the importance of proper water heater maintenance and its impact on your home’s overall plumbing health. That’s why we’ve compiled a list of easy-to-follow, essential water heater maintenance tips to help you keep your appliance in top shape for years to come. These tips not only help you save money on utility bills but also prolong the life of your water heater.

In this article, we’ll discuss several crucial steps you should be taking to maintain your water heater, including inspecting it regularly, testing the temperature and pressure relief valve, draining the tank, and checking for leaks. We’ll also touch on important safety precautions you should follow while performing these tasks.

Regular Inspections are a Must

One of the most critical steps in maintaining your water heater is conducting regular inspections. By routinely examining your water heater, you can identify early signs of problems and address them before they escalate. Additionally, regular inspections allow you to spot any possible safety hazards, such as leaks or damaged components. Here’s a simple checklist to follow during your water heater inspections:

1. Check the overall condition of your water heater to ensure there’s no visible damage or corrosion.

2. Examine the pipe connections to ensure they are tight and secure.

3. Verify that the water heater is vented properly to prevent carbon monoxide hazards.

4. Inspect the temperature and pressure relief valve (T&P valve) for any signs of leakage or damage.

By conducting regular inspections, you’ll be better equipped to address any issues that may arise and keep your water heater running efficiently.

Test the Temperature and Pressure Relief Valve (T&P Valve)

The temperature and pressure relief valve play a crucial role in maintaining the safety and efficiency of your water heater. This valve is designed to release excess pressure and heat should the water heater reach an unsafe level. Testing the T&P valve is crucial to ensure that it functions correctly in case of an emergency. Here’s how you can test your T&P valve:

1. First, locate the T&P valve on your water heater. It’s generally found on the top or side of the water heater tank.

2. Place a bucket under the valve to catch any water that may be released during testing.

3. Lift the valve’s lever slightly and then release it, allowing water to flow through the valve and into the bucket. If no water flows or the valve is stuck and won’t open, it’s time to replace it.

4. Once water flows freely through the valve, release the lever, and the water flow should stop. If it doesn’t, the valve may be faulty and should be replaced.

It’s a good practice to test your T&P valve at least once a year to ensure your water heater’s safety and efficiency.

Drain Your Water Heater Tank Regularly

Over time, sediment and mineral deposits can accumulate at the bottom of your water heater tank. These build-ups can negatively impact the efficiency of your water heater by forcing it to work harder to heat the water. Draining your water heater tank is a simple way to remove sediment build-up and improve its performance. Here’s how you can drain your water heater tank:

1. Turn off the power supply to your water heater. If you have a gas water heater, switch off the gas valve. For electric water heaters, switch off the circuit breaker.

2. Turn off the water supply valve to the water heater.

3. Connect a garden hose to the drain valve located near the bottom of the tank. Make sure the other end of the hose is positioned near a drain or outside.

4. Open a hot water faucet somewhere in your house to let air into the system.

5. Open the drain valve and allow the water to drain out of the tank.

6. Once the tank is empty, close the drain valve and open the water supply valve to refill the tank.

7. Turn the gas valve or circuit breaker back on to restart the water heater.

We recommend draining your water heater tank at least once a year for optimal efficiency.

Keep an Eye Out for Leaks

Water leaks in your water heater can not only lead to water damage but also decrease efficiency. Regularly inspect your water heater for any signs of leaking, paying close attention to pipe connections, the T&P valve, and the base of the tank. If you discover a leak, it’s essential to address it as soon as possible to prevent further damage.

In some cases, a simple tightening of connections may resolve the issue. However, if the leak is due to a more complex issue, such as a damaged T&P valve or corroded tank, professional assistance may be needed.


Proper water heater maintenance is essential for maintaining your home’s hot water supply, improving the efficiency of your appliance, and extending its lifespan. By following these water heater maintenance tips and regularly inspecting your appliance, you’re sure to enjoy a well-functioning water heater for years to come.

We had a sink stop up that, despite our best efforts, couldn't be solved alone. So...I found Miguel via yelp and relied on the other great reviews on here. He, unlike everyone else we called, came out with no upfront service charge, on a Saturday evening and fixed our clogged pipes for a very reasonable cost. We are keeping his contact info on file and definitely plan to make him our go-to guy. Highly recommend
