Hi all,
I'm puttung in the radiators and pipework for a central heating system and the pipework is running under the screed.
The problem I have is that in some parts the screed is 50mm thick and 75mm thick in others.
In the deeper areas I reckon I can plumb in 15mm copper with the lagging on it and still get coverage with the screed.
However, in the 50mm area I don't think that will work out. A plumber suggested to me that I should switch to 10mm copper in the shallow area. Apparently you can buy 10mm pipe with a coat of lagging already on it.
A couple of thoughts here:

A couple of thoughts here:
- If I go down to 10mm in the shallow area, doesn't that mean I will lose flow rate and need to compensate for this with bigger radiators?
- If it does come pre-lagged, what do you do if you solder in some t's and elbows? Strip it back, solder and then re-lag I guess?
