I did my regs about 2.5/3 years ago so things may have changed, but we were taught that a drain was required to allow the pipework to be emptied during icy temperatures to prevent waste of water.

Just looked in my WRAS book and there's no mention of a drain-off in the text or diagrams. Like I say though, I still fit one because it's handy for the customer - if they remember the simple instructions I left them.
How did we digress so far from the talk about a hole in a wall? :confused5:
Why all the fuss bout filling in holes with sealant/grout etc your gonna need access sooner rather than later so I would not bother it looks like a dogs dinner anyway so why not just a little bit of wood paneling?
