Please use the pressure relief valves free of charge to retain your warrantee. The valve with the red lever has a small orifice. You can connect the supplied discharge pipe to  that orifice to drain of drops of expansion water. With this pressure relief valve you do not need an expansion vessel. This pressure relief valve has a non-return valve on the inside that prevents hot water from the water heater returning to the water mains that would create water hammer.

If you intend to use an expansion vessel please make sure you purchase a WRAS approved 7 bar pressure relief valve. This WRAS approved valve can only be used together with a WRAS approved check valve and a WRAS approved expansion vessel to retain your warrantee.

Using the wrong bar pressure relief valve can cause leakage inside the boiler as the working pressure inside the tank will exceed the maximum tank working pressure of 7 bar. It can also cause excessive calcification inside the tank. Calcification on the heating element slows heat transfer and will cause the heating element to overheat. Overheating weakens the steel and will eventually cause the steel to tear resulting in a short circuit.

We strongly recommend to install a pressure reducing valve if the water pressure is too high (5 bar or more) or if you suffer from fluctuating water pressure. High water pressure and/or fluctuating water pressure often occur in apartment building, flats, farms, older houses and houses and buildings in elevated areas. Install a pressure reducing valve where your mains water supply line enters your premises or right behind the pressure relief valve. Ensure the water pressure is set at 3 bar. Any damage caused by a too high water pressure or fluctuating water pressure will not be covered by the warrantee.
