Since removing a radiator to decorate a room I've had a slow leak in the central heating. Luckily I've found where it is - directly below said radiator - I must have moved it about too much in the process. It's ground floor so the water isn't a big problem. Vertical copper radiator pipe joins to the brass elbow, which leaks where the plastic pipe joins it. See photo:
I would like to fix this properly so I don't have to worry about it after replacing the floor, ideally I'd like to do without draining the whole central heating system but will do if necessary to avoid turning ground floor into a swimming pool.
Does anyone have any advice for:
- if it needs replacing or just tightening (there doesn't seem to be anything to tighten - is it push fit?)
- if it needs replacing what to replace with
- how to do this with the least faff/flooding
I'm a novice, but confident to do things myself, based in UK, easy access to Screwfix, Wickes or B&Q.
