"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 ."
"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."
"Seems to be good quality overall - casting and plating look ok. Factory preset to 3-Bar but relatively straightforward to adjust if required. Can't really comment on reliabilty as it's only been in a week!"
"Excellent bit of kit for the price. Easily fitted although you will need to use more care and effort to tighten when using the 22-15mm Olive fitting on 15mm pipe. Ensure you wire wool clean the pipe before fitting PRV. Easy to adjust to the pressure just follow the instructions given. Well satisfied and first time I have used this particular PRV."
"Fitting the PRV proved difficult, due to the force required to tighten fitting when using 15mm reducers. Although factory set to 3bar, gauge gives reading anywhere between 2 and 6 bar, which appears to be connected on the OUTLET side so not sure what's going on here."
"I've got two of these fitted and I've found they start to leak from the cap on the top after about 4 years. The cap has no seal, it just screws in and under constant water pressure it leaks. I've manged to stop it with PTFE tape for a few months, then it started again, so I sealed it with silicone but that only lasted a few weeks so I had to replace the whole valve. The second one is now leaking in the same way. I think the internal rubber diaphragm is failing but they don't seem to sell these separately, and the manufacturer doesn't respond to emails. If your vlave is out of site, then you could well have damp patch on the ceiling before you find out. Avoid if you can."
"The product itself represents excellent value. I have been trying to stop severe water hammer that occurred when the washing machine was changed from hot/cold fill to a new cold fill only machine. The problem is that the solenoid that controls the water flow is very harsh - it stops the water suddently causing "hammer". Having tried "Arrestors" which didn't work I thought I would try a PRV. Fitting itself is straightforward but I wish I had taken heed from other reviewers about the 22/15mm reducer. No matter what I have tried the water entry joint leaks. It is not a trickle but enough to be of concern. Next step is to replace by a 15mm to 22mm copper joint and use a 22mm olive. Why is there no learning from reviewers if a number have reported similar problems ?"
"The 15mm compression reducer with the valve does not work. They leak even with tape. I had to use a copper reducer fitting instead with the 22mm compression on the valve and soldered to the 15mm. Once fitted it works ok and is reliable so far."
"i bought this for as a replacement for a failed unit. when i looked at the inlet although it is a 22mm compression connection the actual drilled porting in the casting is only 8 mm. as this was for whole house pressure reduction including a unvented cylinder i considered this to be too small and will give a lower flow rate than the one it replaced. i fitted this as a temporary device and will be replacing with a larger bore version shortly."
"Bought to reduce pressure to power shower. Forget the 15mm reducers they failed to work at all, would not seal even with being tightened with a pair of 12" pump pliers. I ended having to solder 22mm reducers on to the pipes. The supplied gauge was erratic and then failed completely leaving with me to guess the pressure. What should have been an easy job turned in to a 2 hour nightmare."
