Rated 3 out of 5 by from Bizarre Genuinely pretty baffled by this valve. The plastic pressure gauge (as others have said it’s not a metal connection like in the pictures) has to be fully screwed in or it leaks. Can’t see any way to adjust the orientation on it. So on mine the gauge faces the wall, completely opposite to the pictures provided. Essentially unusable….

Rated 1 out of 5 by from Not as advertised Guage is completely cheap plastic including the threads (nothing like the picture) that doesn't seal properly. When tightened down the guage faces the adjustment knob which means you can't read it side on. Pretty useless, returned. Also no longer Honeywell branded.

Rated 3 out of 5 by from Works but gauge is poor I should have read the reviews first. The quality of the main valve is OK, but the gauge connector is plastic rather than metal and I couldn't get it to seal properly. In my opinion not fit for purpose and not really good enough for a premium brand.

Is there any way to change the orientation of the gauge? Mine faces the wall and is precisely 180 degrees different to the picture shown. If wind it back to face the right way if obviously leaks…

Can this be used for potable (drinking water)?

Asked by: JamieJonathan

How wide is this product?

The main stopcock is in a pretty small/tight area, so not sure if this will fit in my small space.

Pressure gauge

Why is this advertised with a brass threaded pressure gauge yet you sell it with a plastic one. Isn’t that miss selling I’d like the one I thought I was buying rather than a cheap plastic one that can split.

Installation location

Can this PRV be fitted on the pipe just before the shower (so as to effect the shower only), or should it only be installed where the mains enters the house (affecting all outlets in the house).
Asked by: ChrisFromFleet
The pressure reducing valve is designed to protect household appliances against excessive supply pressures. It can be used on any outlet where you want to reduce the pressure.
