Quick and easy to fit direct replacement.
Genuine quality item. Caleffi Pressure Relief Valve 6-Bar. Ensure your water is off at the main stopcock and the pressure has released from your system - we opened the cold taps to ensure this. plenty of towels at the ready around the area "just in case" but there was only a minor trickle when I removed the original defective unit. Cleaned the surface of the pipework to make sure the 2 would create a seal. Joined and tightened on both sides. Gently brought the water back up to normal pressure and checked for [no] drips. Job done! Allow an hour, but it could be done within 20 mins. Only One tool required for the job. I used an adjustable Wide-Jaw wrench/spanner similar to this one https://amzn.eu/d/j3FKatZ As a Prime member it arrived the same day!

stop safety relief valve leaking
This was easy to fit and worked well. The safety relief valve was leaking on our water supply pressure control valve, because we live in a hard water area, and limescale built up on the rim, or seating of the valve, after only 8 months of use. I hope the replacement works for longer now we have a water softener.

Straight swap for existing
This was very easy to fit since it's identical to the original. Finding which PRV is leaking into the tundish is more difficult !
