Caleffi - 22mm Inlet Control Multibloc Valve Group 533002CST by Altecnic Caleffi

The gauge is reading correctly! Just in our area the water pressure is very low. So the regulator can't work at its set pressure of 3 Bar.Missing information:There is no information if you can fit a pressure gauge, or what size thread is needed.A pressure gauge can be fitted by removing the black blanking plug underneath the red pressure relief valve in picture.The thread size is 1/4"BSPT (13mm).I used a larger 63mm 4 Bar Ferro pressure gauge, so that it can be easily seen at a distance.In my situation I didn't use the additional outlet located at the bottom, below the grey cap.It can be blanked off with a 22mm cap (not supplied) - Unfortunately in my case I only used Plummers Mait and PTFE tape to seal the cap, which then leaked. I then had to remove the 22mm cap and fit a fibre washer in the cap, so when the cap is screwed up tight it makes a seal with the inner flang.p.s. This was used on a Bio Mass Pellet Boiler.

Great price, easy to install, quick dispatch

Seems well engineered.

Product as expected

it's working fine too early to give it 5*

I was quoted over £100 plus vat for replacement valve from city plumbing. Never thought to look on Amazon but I did and glad I did. Great quality and easy to fit. Varry happy.

Saved money on a product that works just as well as the more expensive brandedone

Do not get anything else, this is the perfect replacement combination valve. I’ve fitted many, I’ve saved a fortune, probably the best find on amazon,
