Pipework for downstairs radiators on new builds

[Mgrant]

Hi on some new new build houses I plan to first fix the up stairs radiators in 15mm copper coming up though the floor at the pipe centers for the radiator. i,e rad. length add 45mm per side and the correct distance from the finish wall. However I am debating how to feed the downstairs radiators, this pipe work is usual feed behind the dot and dab plaster. What do people find is the best way of doing this. Thanks for any advice.

Haven't done much domestic new builds. Mainly been working on commercial new builds which have all been 15mm to each radiator.

gas safe then?

no hourly rate, have worked for the firm awhile, just this will be the first time doing domestic new builds for them.

so why not fit in 15mm like you normally do and get the lab to chase the walls 🙂

Could be an option, am unlikely to have a lab. though.

Yes thanks for the advice. Do the rad valves above work with polyplumb pipe and liners, or do you need a liner specific to the valve?

no if 10mm valve (not the reducer type) they should but never used poly as most of the time im ripping the stuff out but as with any plastic pipe use an insert/liner

Pegler Push-fit Elbow 10mm | Chrome Compression | NoLinkingToThis Surely these can be used with poly pipe?
