Water Heater Leak Detection
Condensation may sometimes cause your water heater to drip as cold water fills tank and then trickles down. A dripping water heater is frequently noticed when cold water is heated in the tank, and should disappear soon after to indicate condensation. But when a dripping water heater is not the result of condensation – plumbers need to investigate the leaky source.
A leaky water heater can result from the following causes:
A damaged temperature pressure relief (TPR) valve may be leaking out water, and will require immediate repair to prevent thermal expansion that will split open the tank. On the other hand, a perfectly functioning TPR may be discharging water because of excess pressure in tank due to high temperature settings or high water pressure.
Faulty drain valves will cause your water heater to leak out water. Plumbers will either tighten loose drain valves or replace them altogether.
In gas water heaters clogged vents may cause leaks. Unblocking obstructed vents will probably rectify the problem.
Electrical heaters may need to be installed with new heating element gasket to stop water leakage.
Incoming water pipes may be loosely connected to your water heater and leak out water in their fitting point. Plumbers will either tighten piping and fittings or replace with new pipes.
Corroded tanks seep out water. In such a case replacing with new units is the only remedy. If you are planning to buy a new water heater, consider the tankless units that are water and energy efficient and have a longer lifespan than conventional heaters.
