Water Heater Leaking? Here's What To Do | Maxwell Plumb Mechanical Corp.

A leaking water heater can range from a small, barely noticeable drip to a full-blown flood. Either way, the damage to your home and property can be expensive; ranging from damage to walls and floors to unhealthy mold and mildew.

If you see water accumulating near your water heater, it may not actually be coming from the water heater. Nearby appliances and condensation on pipes near the water heater can cause moisture to accumulate nearby. Closely inspect the base of the water heater and valves for signs of leaks.

If you determine the water heater is the cause of the leak, the first step is to turn off power to the water heater. If you have an electric water heater, turn the power off from the circuit breaker. A gas water heater can be shut off from the power supply attached to the unit, usually, be turning a knob to the off position. Next, turn off the water from the cold water shut-off valve located near the top of the water heater.

Water heater leaks can occur in several locations, including the cold water inlet and hot water outlet, the pressure relief valve, the drain valve, and the bottom of the tank. Fixing a water heater is not a do-it-yourself project. A qualified plumber should make the repair. Depending on the location and severity of the leak, your plumber will either have to repair the water heater or recommend replacing it.

Preventing damage from water heater leaks.

For an extra measure of protection from unexpected water heater leaks, specially designed pans can be installed under the water heater to divert water leaks to a nearby floor drain. There are also special water leak alarms that can turn off the water when a leak is detected from the water heater or another source.
