My wife and I are doing up a house and we're finally around to fitting the radiators. I put pipes in place to come out of the walls before the plasterboard and skimming went on but made some wrong assumptions about how the valves are fitted. I thought it would look better if the pipes came out of the wall instead of the floor so I made them come out either side of the radiators level with the valves. The radiator valves are straight (instead of angled) because I was planning on adding an elbow after the pipe exits the wall and then running them straight into the valve and radiator horizontally. See the diagram attached. I've connected them all with nice chrome compression elbows but it leaks, maybe because the pipes aren't aligned quite right and there's a bit of tension on them. I could solder an elbow with the radiator in place, less places for it to leak, but it'll be almost impossible to get the radiator off later without cutting the pipes. Also some of the radiators have plastic pipe just out of reach inside the wall so I can't solder the little bit of copper that's sticking out. I've already had to solder a few extension bits onto other radiators because I didn't leave enough pipe sticking out of the wall. This is all 15mm pipe. We've considered using push-fit elbows like Conex Cuprofit but I suspect they might damage the pipe after removal and they're just as likely to leak as the compression fittings. Or we could use 10mm copper or plastic pipe with a reducer inside the valve and simply bend this from the wall to the radiator. We would still need to reduce the 15mm pipe from the wall to 10mm. Speedfit reducers are big and ugly, Copper pushfit look a bit better but won't take plastic pipe. Ideally, I would have got angled TRVs and brought the pipes out directly below with a bit more movement in them, or I would have used 10mm pipe coming out in the middle of the radiator, or I would cut out the walls and relocate the pipes. Unfortunately, time and budget don't allow this at the moment. I'll know better next time but can anyone suggest a good looking and reasonably leak-proof solution for hooking up our radiators to my awkwardly positioned pipes?
