I am replacing my water main with 25mm MDPE pipe which is coming up vertically, at the required depth in my garage extension, vertically inside a 4" rainwater pipe.
I plan to connect it to the garage tap spur off the old main and disconnect the old main by permanently turning off the old stop tap.
What fittings do I need on the end of the 25mm MDPE? Is it just a stop tap on the MDPE pipe and then something to reduce to the 15mm copper pipe?
Thanks
