A mate had Sky installed recently.
The cable run around inside his front room was shocking. Between staples, it was away from the woodwork by about an inch in places.
And then there are the staples... Right through the middle of the phone cable that he ran kind of twisted together with the sat cable. The socket on the end of the phone cable had bare wires showing and all sorts.
The whole thing looked like it was done by a 5 year old.
IckleMissBish, have you tried just wrapping some duck tape around your pipe? There will be very little pressure in there, so that would seal it enough for you to use until they get it sorted...
