Do you own a storage type boiler hot water cylinder? Then you will have a minimum of 2 pressure blow off valves installed (that's providing your plumbing contractor has done the right thing).
The manufacturer of these blow off valves will recommend that some where between every 3 to 6 months someone should relief these and ensure that they are doing what they are designed for and that is release water from both the hot water cylinder and the cold water mains to the properties.
Majority of manufacturers these days will supply a HTPRV with each tank sold (High Temperature Pressure Relief Valve). This is typically located towards the top of the tank where the water is at its highest temperature and has a short probe which enters the tank. If the temperature of the water in the boiler ever exceeds a safe zone the probe will swell and cause the tank to release itself via this valve rather than blowing the cylinder up itself. The idea is that regular checking of water release will ensure that the blow off device is working or not and the required maintenance can then be ordered if required.
The other type of pressure relief valve which I want to talk about today is known as the CWPRV (Cold Water Pressure Relief Valve). This valve is not supplied with the new boiler, BUT the manufacturer recommends that the plumber provide and install one to comply with the manufacturers warranty, why they don't supply these? Great question. Anyway that's a story for another day, as long as your plumbing contractor is doing the right thing he or she will supply and install one of these with every new install they perform. Once again these are designed to protect the tank from becoming a ticking time bomb, this time these valves will relief due to a spike in the street mains and blow off water to protect the tank from catastrophic damage.
