Guys,
Can anybody tell me whether this a check valve on the fill loop. It's getting on 25 years old but still works fine. What are the ports for? One is capped TEST, would that be pressure test and, therefore, could I install a pressure gauge there as the pressure gauge currently resides on top of the boiler on the pressure relief valve and the fill loop is in the upstairs airing cupboard. Useful!
Thanks.
