Many thanks for your help Chris. One last thing, the instructions also possiby putting a pressure regulator valve in line to maintain a maximum water pressure of 8 bar. Is this a usual fitment to systems ?
I am installing a new Baxi 105e combi boiler and as the system has a one way valve to prevent backfeeding into the mains, the system requires an expension vessel in the cold feed to the boiler. The instructions recommend a Zilmet 160ml R 1/2 15bar unit. Where can I get one of these ?
8) Many...
