These T&P 2-in-1 combination relief valves are the most cost-effective and proven solution for extreme temperature and pressure emergencies.

What causes a pressure relief valve to leak water?

When a relief valve leaks, it is usually due to thermal expansion. When heated, water expands. This creates overpressure in the system. When the T&P relief valve senses this excess pressure, it opens, reducing thermal expansion* and returning the pressure to normal conditions.
