Hi,
Had a new downstairs bathroom fitted with new floor a few months ago which has a central heating drain pipe terminating outside(see photo)
I have opened the compression drain nut to drain a few times previously when changing radiators etc by using two spanners to avoid twisting pipe however a few days ago I did the same and in a stupid moment turned the pipe. The combi boiler has since been refilled etc but still slowly losing pressure.i think I have caused a slow leak on the pipe connection under the suspended bathroom floor. I was tempted to do the same action as to tighten the inaccessible compression joint under the floor as to seal leak but would this work. The only other solution is to rip out a new bathroom and cut through the wooden floor to get access or could I use CH leak sealer though all the pipes off the 22mm loop are 10mm so not sure if that would create a blockage.
