Hello,
so over the weekend I bought the rectractable garden hose from Bunnings.
I drilled the holes for the coach bolts so the wall plug can go in but it doesn’t seem to be sitting properly in the wall at the moment with almost half of them sticking out. I have attached some photos for reference.
The booklet said to drill a 10mm hole for a 8mm plug and that’s what I have done.
not sure what to do here. Looking for advice from experienced members.
