FRANKE Pressure Relief Valve, 2-Port, 1/2 inch Inlet, Barb Outlet

This valve fits a Franke Minerva boiling water device. Mine had started to drip into the Tundish and out through the drain. this new valve completely fixed the problem. Only issue is that it is expensive at £65 but it is the only one that is a direct replacement so you have no choice. Effective though.

Identical replacement for the existing valve. Easy to fit. Arrived promptly. Somewhat pricey as it is a single source (could not find an equivalent to the Franke OEM valve anywhere else)... overall pleased with the replacement...

Living in a hard water area means that, despite regular cleaning, the valve gets gunged-up and eventually needs replacing. The change-over was straight-forward.

The product works, expensive & if I knew what I do now would never have bought the seraphina tap, I've had to repair several times & it's only 3 years old.

These valves are hard to find, so was pleased when I found what I needed. The original valve was fitted by my boiling water tap was fitted, didn't realise it had gone wrong till my water softener started to use massive amounts of salt and my water bill went up. All down to the original valve failing. When I first found this valve I couldn't believe how expensive it was! But bit the bullet and purchased one fitted it and now my salt usage and water usage have dropped significantly. So a small price to pay in the greater scheme of things. Its made well and does exactly what it should do.

Seat on the pressure relief valve wears at one spot and leak starts, as water eats away at the spot it gets worse. Can clean up the seat but then need to pressure test (I temporarily plumbed it into an air compressor) to ensure pressure within limits for the tank, use a 12mm socket spanner to adjust the brass pressure setting nut. Pick out the white top disc, then use fine screwdriver to remove tiny retaining washer, grey cap can be removed. Unscrew the nylon body and valve seat, and any seat defects can be seen. Valve functions without the grey cap so no need to replace. Used a counterbore to clean up seat, or a tap reseating tool.

It was bought as we had a leak and needed replacing. Same brand so we knew it would be a good fit, quick delivery which is a bonus.

Quite expensive but same price everywhere. Used it for my Franke Minerva boiler tap and seems ideal for the job of replacing old pressure valves. Arrived very quickly and efficiently packed.
