    I'm chasing some walls and using speedfit for pipes to the radiators. I'll be using conduit and want to transition to copper ends which will connect to the rads. Can I bury the speedfit fittings (elbows etc)? What are the options for pipe exiting the wall and connecting to the rads? Do I...

    Supporting speedfit pipes under 1st floor floorboards

    Hi. What would you recommend for pipe support whilst running 15mm central heating pipes parallel to floor joists? My idea is to screw wood supports perpendicular to the joists and clip the pipes to the top, or, screw-in wood supports with 22mm holes and pass through the pipe. When the pipe...

    Max distance for 10mm tails off 22mm flow and return

    I’m considering my options for moving (JG) pipework from an inaccessible place whilst the floor is up. One option might be to use 2 x JG 4-port manifolds, mounted in a much more convenient location. But, this would mean adding 2 - 3 metres to the 10mm tails (off flow and return) and i’m not sure...

    As per the title. What do you think of using Speedfit in part of the cental heating system? In particular a 15mm x 300mm flexi pipe. Bent at 90 degrees. See link. Not sure what I am dealing with yet but I suspect a leaky Yorkshire elbow below the floorboards. Rather than remove it, clean it...

It was my first attempt at plumbing and i assumed i could easily move the...

    Burnt speedfit fitting-is it a problem?

    Hi I had to take the plinth boards off in the kitchen to install a new oven and at the back I saw this speedfit fitting. It’s a 10mm fitting on the central heating loop, and it feeds the kitchen radiator. I think it’s the flow feed, not the return. To me it looks like at may have been burnt...

    Hi all, I’ve just installed a two pipe central heating system and need a pressure test. However JG require a wet test at 2 bar then at 10 bar with the pipe disconnected from the rads and boiler.
