Leaking pressure reduction valve

[Orionsbelt]

Hi
My house has a pressure reduction valve fitted after the mains input stopcock. I believe its because i have a boiler-mate system installed.
The house and valve are 16 years old and the valve is slightly leaking
through what i think is the pressure adjustment screw (tube about 3 inches long and 1 inch in dia at 90 deg to the main pipe. The mains pipe nuts are fine.
There is no pressure gauge attached, and there is a small build up of lime scale where the drip forms. Whats the best way to resolve this please, I know new valve are around £50 ish and fitting and pressure checking are going to be about an hours work so thats about £120.
Can I just try moving the adjuster back and forth to clear any crap build up in the body??

Thanks
Orion

I would have expected about £84 to fit a new one plus the cost of the valve.

Moving it incurs a high risk of making it worse!

Pressure reducing valves are available from £20, presuming we are talking 15mm. (Screwfix)

Not too far off what the OP has already said then Tony!!

Thanks all, Engineers coming monday.
£58 plus vat plus parts.

However the Glendhall Boilermate 2 specification says that the Max operating pressure must not exceed 3.5 bar and a limiter should be fitted for that.

I have spoken to Essex water as to the specific pressure in my area and they will give me and answer on Monday morning, but I do not think its anywhere near that (50.5 PSI ) I wish.

So please whats your thoughts if my local water pressure is below 3.5 bar (50.5.psi ) I don't see the need to fit a replacement unit.
I think these were fitted as part of a general design of this house as many have been built in different areas with no recourse to checking the water in the local area.

Please correct me if my thoughts are wrong.

Thanks

I wouls say it was fitted because there is/was a pressure problem, it's certainly not normal to fit them.

Thanks Do It All and others.

All fixed this pm, old valve replaced and new Reliance Valve fitted and pressure set up ok to 3.5 Bar Total cost (including another minor job) of £138 which I'm very happy with. Great Plumber and job well done (he even had a direct replacement valve in his stock room)

And what a difference now have very good water pressure in the whole house.

Some info that might be of help to others.
Essex water gave me the local pressure of 3 to 5.5 Bar so for a boilermate installation I needed a limiter fitted and set to 3.5 bar.

The old valve was a Reliance model P75 DN22 pre set, now on my valve where it was leaking was complete furred up covering the Vent hole.



Job well Done Tks
