Why Is My Water Heater Leaking: Your Guide to Common Causes of a Busted Water Heater
May 02, 2025

When dealing with a leaking water heater, all you want is a fast and convenient solution before the damage becomes irreversible. The good news is that Acknowledge Plumbing can help you fix your unit and restore functionality to your home. If you notice dripping or pooling water near the tank, call a plumber in Arden-Arcade, CA to inspect, diagnose, and recommend the best course of action. While water heater leaks may not raise concerns initially, delaying professional intervention can lead to further damage and costly replacements. Let’s delve into the common causes of water heater leaks to help you make informed decisions.

Age

Like any household appliance, water heaters wear down over time. With that said, they tend to be more prone to leaks, leading to lower water retention and performance. If your water heater is over 8 years old, checking for signs of deterioration regularly is vital to preventing devastating scenarios. Some of the common culprits of leaks in old units include corrosion, cracks, and rust. Even if you can patch up a minor leak, you will eventually need a new water heater.

Drain Valve

The drain valve allows you to empty the tank during maintenance. While it can hold for many years, frequent use can cause it to loosen and leak. Check for mild leaks due to small openings that were not there before, as they show a loose or damaged drain valve. Tighten the valve to stop the leak, but if it does not work, installing a new valve is wise. You can hire a licensed plumber to install and tighten the new valve, giving you peace of mind knowing everything is in top shape.

High Pressure

As the water temperature in the tank increases, so does the pressure. This is usually not a problem, but excess pressure can cause problems if left unchecked. If the pressure builds up in the tank and cannot escape properly, water starts to leak through loose components and cracks. Regularly check the temperature setting on your unit or switch to a tankless system to minimize the risk of such issues. In the case of severe tank damage, your plumbing repair service provider will recommend modern and more efficient models to keep your home running.

Malfunctioning Temperature and Pressure Relief Valve

Another reason you may need water heater repair and maintenance is a malfunctioning temperature and pressure relief valve. As mentioned, intense pressure in the tank can cause water to escape in loose or malfunctioning components. Although the pressure relief valve allows pressure to escape in the form of steam, it can get loose or damaged, prompting a replacement to seal the leak. If the leak persists after replacing worn valves, consult a reputable plumbing repair service to diagnose and fix the problem.

Inlet and Outlet Connection

Conventional units preheat your water in the tank, which comes in through an inlet connection. When the water reaches the desired temperature, it exits the tank through an outlet connection to the various faucets and appliances. As with worn connections, inlet and outlet connections also wear and tear over time due to regular use. If this happens, tightening the connections yourself should fix the problem. However, it is advisable to schedule an inspection with a professional to rule out other possible causes.
