Hi I have moved into a house with 8 mm central heating I want to put a chrome rad in the bathroom should I go for 8mm valves or 15mm with reducer also having never worked on 8 mm have you any tips ,do they make compression fittings for it as the rad in the bathroom has a pegler valve that is flow and return go through same valve the return comes back via a plastic dipper pipe.
Just use 8mm, yes you can get compresson but solder is much better. Get rid of those horrible old twin entry valves.
be careful when removing the rad if you havent drained down, the valve only shuts off one port , so if you remove it it will * all over you :^O [Edited by: admin]
zipdip you might find this interesting, if they zap the link before you see it, go to youtube.com and search 'toms top tips tip 4' for a good tip on how to convert 8mm to 10mm
Yes extend the 8mm pipe and use a nice piece of chrome 15mm copper up to the valves whci would be nice in chrome also. Use compression couplers 15mm*8mm. Item number on here 45857. Will look much better.
