Have you been asked if you have a pressure limiting valve when claiming warranty on taps, dishwashers or washing machines?
So what does a pressure limiting valve do any way?
The pressure reduction valve (PRV), or pressure limiting valve (PLV) is a type of valve used to control or limit the pressure in a system or appliance. The relief valve is designed to open at a predetermined set pressure to protect pressure vessels and other equipment/appliances from being subjected to pressures that exceed their design limit capabilities. When the set pressure is exceeded, the relief valve becomes the "path of least resistance" as the valve is forced open and a portion of the fluid is diverted through the auxiliary route.
Some tap and appliance manufacturers require households to have a pressure limiting valve installed to uphold the warranty on their products. So, as boring as it is, it really is very important to read through the manufacturer's instructions and manuals to see if it applies to your newly purchased product, so that your product performs to the best of its ability and in the event of a warranty claim, you know you're protected.
Pictured in this blog is a PRV that is installed at your water meter. It looks like a simple piece of metal, but it really is a very sophisticated piece of engineering. There are also other types of valves that are installed at the appliance.
