The plastic pipe has a diameter for 37mm and I have had to purchase the closest pipe external pipe lagging size: 40mm.
I've also got 20mm clearance between pipe and wall and hence, opted for the thicker 13mm lagging.
Question: I am happy to slot the lagging over the plastic pipe and tie with the cable ties but I am wondering if there will be a slight weak point where the wall brackets are. I will try to wrap a tie below and above the bracket but would appreciate your thoughts, in case I am missing something.
You can only do your best at prevention... There's no guarantees. It should be fine round the clips... Just make sure your lagging is suitable for outside as the normal foamy stuff just turns to powder after a year or so.
the condensate will not have been freezing inside the vertical pipe, it will have been freezing where the condensate pump tubing goes in to the downward pipe, you need to get that sorted properly and not by the idiot that installed it like that
yup +1. Its not the white 32mm pipe that's the issue. It's the 12mm clear pipe from the condensate pump that is coming through the wall that needs sorted.
The 32mm pipe needs to be cut through the wall and run inside and then the clear plastic pipe is connected to it in there. If it was installed like that I would also be looking to see what the 32mm pipe runs into at ground level. It shouldn't just be stuck into the ground, it should be fitted into a plastic soakaway tub that is filled with limestone chips.
