Have been sadly let down by a plumber and doing the first fix for a new build. I have questions regarding the correct procedure for chasing in pipework behind what will be dot and dabbed..
Its 3 bed bungalow with 9 radiators in total.
I was planning on running lagged plastic22mm flow / returns in the roof space to and tee off 15s for each radiator. Some of which are underneath windows.
1. How deep do you usually chase when its being dot and dabbed? And do you also just take a notch out of the wall plate?
2. Would you chase one larger channel and run both pipes in the same place?
Does the plastic need to be insulated or ducted in some way so it could potentially be removed at a later date?
3. The rads will be attached to chrome.. would compression fittings with liquid ptfe be ok to use to connect the chrome to plastic? But obvioulsy this wont be able to be removed at a later date without pulling the wall apart.
4. How would you chase it in? Straight line down the wall with an elbow at rad pipe height?
Finally anything else ive overlooked / missing? How would you usually approach this job?
Thanks in advance for any help
