Walked into our tiled bathroom 2 days ago, and realised our tiles were squelching a bit...sealed floor (I think, certainly seems that way), small amount of water under the tiles by the loo.
Further investigations led to me spotting a drip off the trap, that ran down the woodwork and to the concrete pad/floor. Dried it off, thinking condensation..no, still dripping. Dried the underside of the tank etc..no, still doing it. Very slight.
Droplets form on the underside of the tank, then run down the pan flush moulding, drip off that onto the trap, run round the trap and drip on the floor.
I can hear the (bottom) inlet valve dripping too - fairly constant, 2 per second, near enough.
So initially I thought "overflow". Whipped the cistern lid off..it's a single button push flush, lever on the bottom of the button that pushes down on the flush mech, but not attached to it. I can see the inlet valve (looks like a normal valve to me with ballcock).
It is indeed dripping slightly. However, tank level isn't high, in fact from the blue lines round the tank (water block left by PO I think), the water has been a good 2 inches higher at some point.
What I can't see is an overflow..there's a blanked off plate on the one side, where the fill valve is on the other, apart from the the ceramic cistern is without anything obvious..not at the sides either.
The flush valve is...erm..blue/white bodied, and in the cylinder at the end where the button pushes, there is a smaller internal cylinder that rises higher...I'm guessing that's the flush actuator, and the gap between it and the "external" cylinder is an overflow..in which case it's nowhere near it.
I've read about the bolt on close-coupled leaking if they pass from tank to pan...there are no bolts in the cistern bottom internally, but there are coming through the pan..so I guess that rules it out.
Fill valve is dry on the tank outside, as is blanked off opening. Which leaves something in the close-coupled bit. When flushed it's fine, it's just when standing and filled it's dripping.
I have a plumber coming out today, but any suggestions anyway? I'm guessing the flush/cistern seal is leaking a bit at the joint suddenly..but why would it drip and not get worse when flushed, if the seal between pan and tank is going?
I can see obvious rust on the bottom of the tank on the blanked off side (mounting plate/bolts I assume..ceramic doesn't rust..), and blue staining under the tank/on the flush pan like a trickle of tainted water..which could be condensation runoff I guess, with the loo block mixed in.
If it helps, the bathroom was refitted in 1997 by the PO of the house, and the entire damn bathroom suite is often seen in Homebase..heh..no idea on what type of mech/loo manufacturer.
If anyone could explain the principle of how the heck there's an overflow on the things as well, I'd appreciate it...I'm used to the older syphon jobs with an obvious pipe on the tank..!
