Have a leak in loo

GrumpyMe

Can't figure out from where.
Not constant may be dry for days, at least without showing.


Exit points stay dry - green arrows.


What looks like soil liquid appears first in damp grouting - red arrows (no RAF jokes please) and then as a small wet puddle surrounding the base.
Reached down the inside as far as possible but couldn't feel any cracks or lumps or bumps. Outside all round is blemish free without cracks.


Soil pipe exit and further on, wall connection are dry.
Leak appears to originate under the base rim.


Is that possible? How to check?

Probably unfortunately a case of lifting it completely, specifically to have a good visual inspection underneath for cracks. A hairline crack in the U-bend may not be visible unless you have your nose right up against it and you won't be able to feel it. But nevertheless will allow water through.

where the first green arrow is put connecting to toilet, forgot name of that hose, but every hardware store has one, it has some sort of silicon housing around it that tears over the years thus small leaks start to appear, second place is where pipe comes in to feed water into toilet is also prone to become lose as its held by silicon plastic housing.


simply but some paper on the bottom just under the waste pipe where it connects and flush it, leave it for few minutes. Do the same at the fill valve.


crack would be very unusual, either way the hoses and fittings needed for both cost like 30e max to replace also try to wiggle top feed valve pipe, and remove waste hose from toilet - nasty but will give idea if the rubber seal has tears in it or has become lose.


as those two parts need to become slightly damaged or lose say when your sitting down standing up to become damaged.

edit: read about arrow placement could be that its cracked given you describe its coming from under so if above methods prove theres no damp or water as it can still run down around, close cold water feed flush it out and unscrew toilet itself for inspection from underneath.

as recently redone mine bathroom entirely and it was leaking on the back for years, thou it was from rusted screws thus this allowed for hoses to be pulled and ripped in time when someone was on the seat. But if its other way around then place some paper towels round green areas and see if you can rock the toilet a bit while doing flushes.
Not pleasant work but its a toilet at the end of the day so gloves and few rags to unmount it and check if it needs replaced.

The loo is where I alway have a leak. Unless I’m in the garden.
