Water heater manufacturers state that a TPR discharge pipe is required to direct hot water to the exterior or a suitable drain location. TPR discharge pipes are required to be made of copper, CPVC, or PEX pipe. PVC piping or plastic tubing is unsuitable for a discharge pipe due to the scalding water temperatures.

  2. Excessive noise: If your hot water heater is rattling or emitting a high-pitched whistling noise, it’s likely the sound of steam trying to escape the tank, which is a sign of far too much pressure pressing against the inner walls.

Is it normal for a pressure relief valve to leak?

The most common cause of a temperature and pressure relief valve leaking is simply malfunction due to age. After years of use, the t&p valve can be too old to work properly. In this case, simply replacing the t&p valve should fix the problem. If the temperature and pressure relief valve is faulty, it can also leak.
