Why Is My Water Heater Leaking?

A leaking water heater tank.

The question “Why is my water heater leaking?” is one that many homeowners grapple with. A leaking water heater can be a small inconvenience or a significant problem leading to water damage in your home. This guide will delve into the reasons your water heater could be leaking and provide useful insight into water heater repair procedures.

Faulty Drain Valve

One common culprit is the drain valve. If not correctly closed, a leaking drain valve can lead to water leakage. Sometimes, the valve may also develop faults, causing it to leak even when it’s fully closed.

Corroded Water Heater Tank

The water heater tank itself can actually be what causes a water heater to leak. Over time, sediment builds up inside the tank, causing it to corrode and eventually leak. This is especially common in areas with hard water, as the minerals in the water can hasten the tank’s corrosion.

T&P Valve

Another common reason is excessive pressure in the tank caused by the temperature being set too high. This will cause the temperature and pressure relief valve (or T&P valve) to open, releasing some water to relieve the pressure. The T&P valve is designed to keep the pressure in the tank at a safe level. 

Hot Water Heater Leaking from the Bottom

A hot water heater leaking from the bottom is often a sign of a serious issue. This could mean that the bottom of the tank has started corroding or that the T&P valve is releasing water. The latter could be due to high water pressure or a faulty T&P valve.

Inlet and Outlet Connections

Loose inlet and outlet connections could also be what causes a water heater to leak. Cold water enters the tank through the inlet, while hot water leaves through the outlet. If these connections are not tight, they could lead to leaks.

Damaged Anode Rod

The anode rod in your water heater is designed to attract corrosive elements in the water, protecting the tank. If this rod is worn out, it can lead to the water heater tank corroding and subsequently leaking.

Fixing A Leaking Water Heater

Now that we know what causes a water heater to leak, the question becomes how to repair it. Fixing a leaking water heater can involve inspecting the tank for damage, checking the pressure, cleaning the tank, or even replacing components such as the T&P valve or anode rod.

Water heater repair is not a task for the inexperienced. For instance, working on a gas water heater without the necessary skills can be hazardous. This is where professional plumbing services come in. At PGA Inc., our team of experts is available to assist with all of your water heater needs.
