"Good bit of kit but very difficult to seal when used with 15mm pipe as the reducing rings do not seal easily. Recommend you buy a couple of female Coupler 15mm x ¾" (38542) to reduce the 22mm to 15mm more reliably then life becomes good again."
"I've been struggling with cold water pressure through a mixer shower making the shower run cold. i fitted this to the incoming mains cold water, and have turned it right down. easy enough to fit, but i'm using 15mm plastic pipework and you need to make sure it's very tight. i have a slight leak, but i have a bowl under it. it has certainly balanced out the pressure better.
I think i'll have to replace the plastic pipe with copper when i have more free time."
"easy to fit to 20mm pipe. no problem to adjust the pressure, and the gauge was accurate. Don't know re reliability just fitted, will wait and see, but looked good quality and back by Screwfix guarantee, will be a piece of mind."
"I have used several of these now as a direct replacement in a block of flats. I have had no problems and first one has been in over 1 year now. Easy to fit, thread on pressure gauge needs lots of PTFE tape to fit tightly into valve but have not had any leaks."
"I was sceptical that a PRV at this price would actually work - but it does and very well. I use them for bidet showers and they very effectively reduce a 5 bar supply to 1 bar.
The pressure gauge is a nice touch and very useful for setting up. I don't particularly like the snap-off 22/15mm reducers but they do seal if you do them up really tight, some lubricant on the threads makes it easier.
I can't vouch for how well they would handle the larger flow if fitted to the rising main nor how reliable they are in the long term but I'm impressed so far ."
"Never fitted such an item before. The instruction sheet was very clear. The brass 22 to 15mm reducing ring needed good tightening to get it to 'snap', but sealed ok onto the brass 'Tap Tail Adapter' used on the outlet side, and the copper 22 to 15mm Reducer sealed ok using the 22mm inlet nut/olive. Good product."
"As stated by others when reducing down to 15mm it can leak. Tip:- as it has to be so tight it is easier if you can fit the 15mm each side of the valve before you fit it and offer the assembly up and connect each end of the pipe to your pipe work. When tightening you have to do it hard enough until you here the reduction ring snap, you ready have to do it tight!!!! Which is why it's easier doing these joints on the floor first. A bit of paste around the joints is a good idea as well (belt and brasses). I did all of the above and had no leak problem at all. Valve easy to adjust with the screw in the top and coming with the gauge good valve for money."
"Brought as a straight like for like replacement as the previous one had started to leak around the joint where the black upper case meets the body of the valve. Like previous comment the previous one was only a few years old so will be keeping an eye on this one. Bonus that it was easy to fit and no damage caused by the leak! Works well and easily adjusted to suit the pressure required."
"A compact PRV which is ideal for domestic installations where the mains pressure is above 5 bar. The preset (3 Bar) is perfect for drinking water taps and prevents splashing if the tap is turned full on. In a previous installation, the pressure gauge leaked slightly from the bod after some time in service."
