Material to absorb water as backup

[john2k]

I’m doing my bathroom and will have a concealed cistern. 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 have just incase of really tiny weeps.

I work on cars quite a bit mainly Toyota and noticed Toyota put a foam like material just under the radiator to be able to easily absorb and dry up from small amount of water. Wondering if there is anything like this I can buy to put on the floor as an extra worst case scenario backup

An old towel, but ask yourself whether it’s better to know there’s a problem sooner rather than later. Practice your skills offline if necessary and develop confidence in them. Leave the cistern as exposed or accessible as possible for a few days, if it’s not leaking before then you shouldn’t have a problem.

Toilet tissue around possible leak sources, pipe joints, etc., quickly shows up any leakage.

After doing diy plumbing, I wrap a piece of loo paper around joints which changes in appearance if it gets wet.
I also put a foil container under any suspect places to catch drips and look every couple of days.

At work I had an AV studio that, for reasons only known to the architects, had the bathrooms next door and they plumbed the waste through the adjoining wall. A couple of times a year they would back up and flood the place.
you can buy cheap leak detectors that are basically a circuit that runs on battery and sits on pins as legs. Any moisture connects the pins and sets off the loud alarm.

Agreed but condensation can be misleading
