Any advice please? I have a 10x6 metre self build bungalow and need to lay plastic barrier pipework through the ceiling joists for my rads (running rad pipes down from the ceiling.) 22mm flow pipes and 15mm spurs to and from the rads.
The question is should I run the 22mm pipe straight down...
I would appreciate some help! I am planning on building a 1 3/4 cottage style house (due to planning restrictions.) The inner block work will rise approx 1 metre above the ceiling joists so the rafters will need to rest on the wallplate with no lateral tie. The property will have dormer windows...
