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!

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 !

Perfect and quite a bit cheaper than local plumbers merchant
Did the job and I think it was half the price of my local plumbers merchant for the exact same thing. Crazy!
