PRESSURE REDUCING VALVE C/W GAUGE 15MM / 22MM

I had no dislike at all it is a good product

This works well enough, but the reducers for 15mm pipe (which had been carefully prepared) could not be persuaded to stop weeping until I soldered them on to the pipes.

Gauge didn’t work

Very easy to fit and it reduces the inlet pressure. Easy to adjust the reduced pressure.

I bought this to reduce the pressure from my mains water system down to 1.5 BAR connecting it to my sealed central heating system to ensure its always topped up and the right pressure. A precautionary fit to deal with any very minor leaks that may happen. I fitted it using the 22mm couplings the reducers I binned they didn't come with 'O'/washer seals anyway.

I had a problem with cold backfeed into the hot water circuit causing overflowing of the loft tank. It was caused by fitting a shower mixer (bought from Amazon) that was allegedly pressure balanced but was not. Using this valve on the cold main feed to upstairs and knocking back the pressure cured the problem a treat. As another reviewer mentioned, the olive/reducers for 15mm pipe require some serious tightening to achieve a seal but they do get there if you're brave enough to give them some welly. It's been installed for a few weeks now and there's been no recurrence of the backfeed/overflowing. I'd recommend this valve to anyone with high mains pressure problems.

Great but the 15mm reducers don't work. Both ends weep. Will replace with 22mm fittings and step down. Very annoying.

Good product, you have to be careful not to over tighten to stop the leaks. Would recommend
