Afternoon all!
Need to start 1st soon on my renovation on my bungalow - currently constructing some stud walls and plasterboarding in the bathroom/ensuite areas. They are adjacent to one another and both of them have a wall that backs onto the loft area where the cylinder will be.
I wanted to run my plastic from where the taps etc will be thru this wall and label them so the plumber can hook them up....but would like to know the rule of thumb when it comes to when 22mm pipe should change to 15mm....my cousin tells me run 22mm as far as you can go and tee off last-minute ....
So would I
A) run 15mm everywhere in the bathrooms and once it penetrated the wall into the loft, the plumber will take over with 22mm
B) take 22mm all the way to the location of the fitting, and just 15mm the final 500-1000mm
C) something different?!
TIA guys !
