What TPR Valves Do

TPR valves relieve the excessive pressure that may build up in water heating systems and other tanks. TPR valves open when the temperature or pressure of a tank exceeds safe levels, releasing steam and hot water to reduce the risk of explosion. The TPR valve works as an automatic safety release on a pressurized steam boiler (like those used by many hair salons). TPR valves can’t prevent leaks from happening; they can only help control the damage if one does happen, by venting excess pressure before it becomes too great and endangering property and life alike. They also minimize scalding because once the TPR valve opens and releases some of the hot water, the remaining water is cooler. When TPR valves function as they’re supposed to, they provide an extra level of safety for both property and human life.

How TPR Valves Work

TPR valves are activated by the temperature or pressure of a tank. When either the temperature or pressure exceeds safe levels, the TPR valve will open and release steam and hot water until it reaches a safe level again. This helps prevent excessive pressure from building up in the tank, which could lead to an explosion. TPR valves should not be confused with thermostatic mixing valves (TMVs), which help regulate the temperature of the water coming out of a faucet.

Why TPR Valves Are Important

TPR valves are important because they help protect against potentially dangerous situations that can occur when excessive pressure builds up in a tank. TPR valves release excess pressure before it becomes too great, helping to prevent explosions and minimize scalding. They provide an extra level of safety for both property and human life. TPR valves should be installed on any tank that has the potential to build up excessive pressure, such as water heaters, boilers, and storage tanks. If you’re not sure whether or not your tank needs a TPR valve, contact a professional plumber. TPR valves are an important part of any plumbing system and should be used whenever possible.
