Dereve Governor Regulator

[chuckalicious]

Hi folks. Done a wee search and found part of the answer, but not all of it.

Basically, I have lower water pressure than all of my neighbours and I have a pressure regulator on the cold mains coming into the house, just after the stopcock.

The bathrooms have thermostatic mixers which are wall mounted, if that's important.

We replaced the boiler with a decent combi when we bought the place a few years ago.

The water pressure to our outside tap and one of the bathroom showers (electric) is poor meaning we don't get what I imagine they are capable of (correct me if I'm wrong).

Basically, I don't know why the regulator is there in the first place, as it is controlling the pressure to the whole house.

And secondly, is it a simple matter of turing off the mains at the stopcock and replacing the regulator with a length of pipe?

Cheers.

You really want to do a pressure/flow test and that'll tell you for sure. If you want to remove the Pressure Reducing Valve then yes it's just a case of removal and replace with pipe. That being said what is it set to as they normally wouldn't be set much lower than 3bar. It may also need the filter cleaned if it has one.

To be fair yes, doing a test would be sensible. I could manage the flow rate but not a pressure test.

No idea what it's set to, it's just a screw type. Just seems odd to be on the main to the whole house whereas everywhere else I've read people have them just before a cold tap or something else specific.

Not necessarrily, if there is a pressure issue into a house - usually where the pressure is too high or erratic - then a Pressure Regulating/Reducing Valve (PRV) would be placed immediately after the mains stop tap.
You say your pressure is too low? If that was the case and I was asked to survey it, I would disconnect the mains after the stop tap, and introduce a same sized pipe after the valve with a tee and fit an adapter to allow the fitting of a pressure gauge and test the dynamic pressure and flow at that point.

Would give the perfect starting point.
