Why is my water heater leaking?

February 19, 2024

If you've noticed puddles around your water heater unit, it's essential to address the problem right away to avoid potential damage and ensure the longevity of your appliance. So, why do water heaters leak? Here are some of the most common reasons:

The most common cause of a water heater leaking is a damaged pressure relief valve. The pressure relief valve is a crucial safety component of your water heater, responsible for releasing excess pressure to prevent tank explosions. If this valve malfunctions or is set at an incorrect pressure, it can cause water to leak. Check for signs of corrosion, mineral buildup, or a faulty valve that might be causing the issue.

Over time, sediment can accumulate at the bottom of your water heater tank. This buildup can lead to overheating, increased pressure, and ultimately, leaks. Regularly flushing your water heater to remove sediment can help prevent this issue.

Corrosion is also a common culprit for water heater leaks. Inspect the exterior of your unit for any signs of rust or corrosion, paying special attention to the tank and connections. If you notice rust, make sure you find a way to prevent further deterioration.

Water heaters have numerous connections, fittings, and valves. Over time, these components can loosen, degrade, or develop leaks. Inspect all the connections, including the inlet and outlet pipes, for any signs of water leakage. Tightening or replacing faulty connections can often resolve the issue.

The next thing to check is the Temperature and Pressure Relief (TPR) valve. The TPR should have a dedicated drain line to direct water safely outside. If this drain line is clogged or damaged, water might pool around the unit. Ensure that the drain line is clear and free from obstructions.

If you've identified the cause of your water heater leak and feel confident in resolving it yourself, go ahead and take the right steps carefully. However, if the issue persists, or you're unsure about the root cause, we recommend bringing in a professional to not accidentally cause any more damage.
