Pressure relief valve discharge, hints from a home inspector
Pressure relief valve discharge not terminated outside
or within 6" to 12" of ground or floor trapped: the "TP" valve is a safety device which is both pressure and temperature sensitive. If the temperature or pressure builds up too high, the relief valve will discharge water to relieve the problem. The water being discharged may be extremely hot, and for this reason, the relief discharge pipe should be directed outside the building, down towards the ground, and approximately 6 to 12 inches above the ground. Do not terminate the relief valve discharge under the building. In the event the
TP valve discharged one would not be alerted, while the discharged water may subsequently damage the foundation, etc.
