Hi there, My landlord has recently had installed a Heatrae Sadia Amtec boiler C600, However the pressure release valve has not been connected, and when it vents, the water goes everywhere cusasing a mess. This happened when I inadvertently put to much pressure in the system. All in all I have decided that the simplest answer is to connect this to a nearby waste pipe, however I am having difficulty recognising the size of the connection on the valve it is neither 15mm or 22mm, my closest guess is either 10mm or 12mm. it would be helpfull if someone could tell me what size this is.
Thank you
Baz
