Hi,
Got a leak today & on pulling up the boards I found that the outlet from the pump on 25mm goes to what looks like 2 sets of 8 10mm pipe connections in parallel. The outflow & return seem to connect to the same pipe with no valves or anything like that, just straight connections that then links back to the boiler.
I cant quite see how the rads get a flow from this set up unless there's some non return valves hidden somewhere & it might explain why they've never been hot.
I'm assuming this is some cobbled single pipe version & I'm thinking of changing it to a two pipe system. Any advice anyone can give on what kind of a set up this is would be much appreciated. It has a standard header tank with return, 2 thermostat controlled valves & pump.
I've linked photos below of what's there in the junction, each set of paired pipes is going to one rad, 8 reds in total. Cheers.
