Hot Water Heater Leaking From Top Seam

2. Temperature and the Pressure Valve

The temperature valve and the pressure relief valve are usually located either on the side of the tank or at the top. It is important to check closely to confirm if there is any leakage on the valves. If there is as leakage, especially from the threads, simply remove the valve. This will help you determine if this is the problem and if this is the case, you may be required to replace the T/P valve.

3. Defective Water Inlet Valve

Presence of water on top of your water heater is an indication of a leak on either the outlet or the inlet pipe. Check the cold water inlet pipe first, and turn off the water flowing to your water heater, using an in-line valve or a gate valve. If there is dripping, it can be rectified by tightening the nuts that connect the handle. If the problem persists, it may be a sign that the valve is damaged and needs to be replaced.

When your hot water system begins to leak from the top seam it is important to quickly fix the problem since this water can drain down and cause electrical problems. It can also cause property damage like your carpet and the lower part of your walls leading to mold growth.
