    Danfoss RAS-C2 10mm swapping out

    I’m planning to drain down my system to replace the 3 way valve which has been buzzing away for months and occasionally sticking. While I’ve got the radiators drained I was hoping to also swap out a TRV which has been unreliable since it was first fitted a few years ago. All the other TRVs are...

    10mm Heating pipes - lagged in loft?

    Hello, 10mm copper heating pipes in loft were lagged with felt. Have extended the pipes with plastic. I I an assuming that plastic 10mm pipe in loft space should be lagged as it can still freeze.

    15mm Towel radiator valves with 10mm supply

    I've bought a new chrome towel radiator as the old one is all rusty. I also bought new angled (standard) valves, 1/2" X 15mm as they too are old and rusty. But when I look at what comes out of the wall, it's clearly not 15mm pipe, looks more like 10mm (plastic). How have they gone from 15mm...

    Fitting to extend pipe 10mm for shower

    Hi, I bought a new mixer shower. Was hoping to just swap the old bar for the new... never that easy though. The original pipes are only projecting past the tiles roughly 25mm.

    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...

    Hi. I'm looking to run a rad supply using 10mm plastic-coated copper pipe and, as it'll be under a laminate floor, to use as few actual fittings as possible.

    Connecting 15mm regular TRV to 10mm pex pipe

    Has anyone got any advise on this please. Can I use a compression reducer to connect a 15mm TRV to a 10mm pex pipe? Not sure if the compression would hold onto the pex pipe. Or do I have to go from TRV > copper > pex. Thanks, Mark
