How Much To Install Pressure Reducing Valve

[GazzaS]

Hi,

Recently I have been finding that taps and toilets have been developing leaks one after another. Upon investigation I have found that there is a pressure reducing valve installed in our cellar which states it is set at its minimum of 2 bar. First off I don't think this is correct and if it is it seems still way to high.

Is it therefore possible to install another valve in series and if so how much should I look to pay for a professional to do this?

Cheers,

Gary

Who knows without seeing it or any information.

£100.00 ish supply and fit.

It would be a plan to fit a gauge to either the new one or the old one, and you can see what the pressure is. £25.00 ish plus labour.

Yes, that seems like a sensible price for that job, It's got to be about £60 for the Labour and as mentioned £25 for the part Plus Vear And Tear of course.

GazzaS - regarding your water pressure. Our local water board (Sutton & East Surrey) aims to provide water to the stopcock outside at 10m head. This works out to just over 14psi - 1 bar more or less.
Your water pressure must be pretty ferocious in comparison.

Am i missing something......2 bar is perfectly normal.....maybe even 3-4 bar but thats high end. Why a reducing valve? And if the items have been fitted correctly i doubt just pressure will be causing them to leak.....corroded washers maybe?

I think you will find that is the minimum

I lived in South Croydon for most of my life and was with Sutton and East Surrey for some of the time. Parts of their supply area were notorious for low water pressure.

Ive went out to a villiage near Luton several months back where the mains pressure was 8 bar!

D.H. - It certainly is at the top of the hill that I live on! The pressure must always have been low around here 'cos the 1930s builders got away with 6lb lead pipe for the water main. It was quite a job finding an adapter that would clamp onto it.

Hi,

Thanks for all your replies

I know 2 bar is OK, but I don't think the valve is working correctly as putting my finger over the tap and just turning the tap sligtly I get soaked I'm sure the real pressure is much higher.

Also turning on any mains fed taps soaks everything. The valve is about 25 years old so I think it needs replacing.

Thanks again,

Gary

Most of the pressure reducing valves can be adjusted!

For a domestic supply I would suggest 1.5 Bar is totally adequate.

Then there is the "headroom" ! The valve needs a minimum of about 0.5 bar differential to perform as expected.

If you cannot adjust it then replace it with a modern one and set it to 1.5 bar.

The taps leaking may just be because they need new washers or there may be dirt in the supply. If you suspect that fit a line strainer.

get yourself upto the west coast of scotland.....7bar easy........have to fit pressure reducing valves to stop heat exhangers bursting every year...
