A pressure reducing valve helps to regulate water pressure on plumbing systems. If water pressure is too high or is fluctuating it can affect the performance and lifespan of heating and hot water systems. It can also impact on other products around the home that are fed by mains water. The water heater pressure relief valve is in place so that it can relieve excess pressure and temperature in a water heater if either of these is too high. Because this everyday appliance is a closed system, thermal expansion occurs in water heaters. Here's how it works.

PRVs, also sometimes known as safety release valves, are in place to prevent a buildup of pressure. The valve opens to release pressure when the level becomes too high, and closes again when the pressure has dropped to within a safe range. They can be used in all kinds of appliances and industries, including boilers and water heaters as well as.

The valves are designed to be fitted to the upper portion of a hot water cylinder as this is where the hottest temperatures in the system will be found. If the system rises above 95°C, the wax mixture within the element of the temperature probe will expand, this will lift the valve off its seat and release water to waste, therefore reducing the pressure within the cylinder. hotun was developed and designed to specifically meet all the Water and Building Regulation requirements and is the first, Single Product Solution on the market, to connect a T/PRV discharge to a tundish and thereafter to an internal drain/soil pipe, achieving the correct performance and regulatory requirements. hotun - it's not just a tundish
