Hi all..
I have just had a kitchen extension, and need to plumb in the waste in for the sink, washing machine and dishwasher..
I was thinking of using 40mm pipe foir this, and get one of those traps that have the waste pipe for the washing machine etc built in..
My main problem is, I need to drill through the wall, which consist of a skim of plaster on plaster board that has been dot and dabbed onto thermal block with a cavity, insulation then brick..
So shall I use a 42mm hole cutter, right the way through, on an SDS drill but not on hammer, then feed the pipe through and silicon seal each side..
Do I need to be aware of any angles that the pipe runs through the wall..
Hope this all makes sense..
Thanks kindly in advance..
