    Material to absorb water as backup

I’ve rippped my old one out and it was badly fitted and has been weeping for years but there is this sort of material on the floor that’s bone dry but deformed from how much water it’s sucked up. So got me thinking it’s a nice backup to...

    Two downstairs radiators cold after boiler service

    I had a Baxi engineer come and change pressure relief valve on my combi boiler and also recharged the vessel. But later I noticed that two radiators downstairs were not heating up at all.

    I have a bathroom wall that’s about 2.3m wide and 2.3m high. There’s a small window in it (around 64cm x 92cm).

    I’m installing a wall-hung toilet frame and need to build a boxed-out stud wall for it. The toilet will sit under a bathroom window, so the new stud wall will only be about 125 cm high and will stick out from the existing wall around 20–25 cm. Because of the window, the studs can’t run all the...
