Multi-part grumble.
We have a problem with air getting into the heating pipes. Causes airlocks and other circulation issues.
One bedroom smells damp, so we wondered if there was a leak below that room.
To get access to under that floor, I could either:
Pull up carpet and cut a hatch into the floorboards.
Or,
Go in through existing hatch and make access ways through the supporting walls (there are four of these, running the length of the house under the floor).
I decided to the latter, as it would give me access under the whole house.
Did I mention that I'm mildly claustrophobic and scared of the dark? The underfloor space is 3-2ft high, wet, muddy and, of course, dark.
4 horrible hours work with a kango, hammer and chisel, I have the access ways cut and lintels added.
No leak in pipes that I can see.
What I can see, however, is that the pipes aren't supported. They just added 90degree bends, shoved them through the floor and connected to radiators.
So there are 10-20ft lengths of pipe suspended by nothing more than the pipe fitting on the rads. They are also uninsulated and 5-7cm clear of the joists, so I can't simply add pipe clips.
Very much inclined to redo the whole thing with plastic, properly.
