My neighbour has a pool of water that mysteriously appears on her bathroom floor at random times usually once or twice a week.
It appears on the floor in the 18" space between the toilet and the bath and appears even when she is not in the flat.
I strongly suspect that it is coming over the top of the pan as I have found the lip to be wet (she is in a 1st floor flat so is this even likely?)
It has been going on for ages, I have brilliantly suggested a time lapse camera but she won't have that in her bathroom. I have also suggested putting one of those blue things in the cistern.
Any other ideas as to how to get to the bottom of the mystery pool of water?
But if it occurs when nobody is there, then who flushes the toilet?
I was thinking maybe a leak in the pan which seeps out over time where some
water remains in the bottom and if its not flushed a give away would be that
this little pool in the pan is empty when the puddle appears. Sadly if that
is the cause they need a new pan.
May years ago this happened to us here, but the pan was extremely old and
if one looked carefully there was a crack in the neck part between the screw
down bit and the neck bit. I'm sure there are technical terms for this.
Apart from that are there any other sources of water around, like pipes
going up to taps etc that might have a seep and this place happens to be
allow point of the floor?

I had the same thing, It was one or two drops every flush dripping
from one of the bolts/wingnuts that secure the cistern to the pan, but
there was some condensation as well, and I blamed that at first.
A new close coupling kit, and doughnut sorted it.
Yes, if it's a close-coupled cistern, I would suspect a leaking doughnut
- which allows a small quantity of water to escape each time the toilet
Go and flush the toilet a time or two, and have a close look at that area.
I was going to suggest that whether it is close coupled or not. One way
I sometimes detect small leaks is to wrap a couple of sheets of toilet
paper around the suspect area and see if it gets damp. Works around
radiator valves too.
Mr Pounder - good tip.
Phil L - we are talking about a couple of pints of water here, too much to be condensation.
M...hotmail - I did get her to use custard powder which led me to believe that the streaks left on the side of the pan pointed to it overflowing but the results overall were inconclusive (to her mind anyway).
Then presumably something is causing the water level
in the pan to rise up and overflow onto the floor while
she is out. Likely a sewer backup problem. But didn’t you
say that its on the first floor ? In that case it must be one
hell of a sewer backup problem.
OK - how about this. The ball valve doesn't shut off the water
completely when the cistern is at the correct level - and has a slight
drip which slowly raises the level. This is not noticeable when the
toilet is flushed frequently but, if left for a longer time, can reach a
level where it overflows. This would have to be combined with a failure
of the overflow to carry the water away safely - maybe a leak where the
overflow pipe comes out of the side - or bottom - of the cistern.
You could test this by purposely holding the ball-valve down and
How else would excess water from a dripping ball valve escape if not through
an overflow. How does the other type of cistern work which doesn't need an
overflow? Is it possible/legal for the overflow to drain into the normal
outflow from the cistern to the pan? If it is, I'm not sure why all cisterns
don't have this sort of overflow.
Clearly you are out of date. Most modern cisterns overflow into the pan and
do not need an external overflow (or Warning Pipe as we were told to call
them). Most cisterns have a cut away area at the back so that if the
overflow is blocked the water will run down the wall - I think it serves to
prevent people setting the water level too high.
If they do it now (ie it's not contravening some safety regulation) I wonder
why toilet cisterns were *ever* made with external overflows, given that the
overflow pipe could always be connected by T piece into the outlet pipe of
the cistern to the pan - even in the days before flush-fit cistern/pan
I agree, though, that it makes it almost impossible to tell when the cistern
is overflowing and therefore that the ball valve needs some attention.
But how many (rented) properties do you see where a constantly dribbling
overflow from a horizontal pipe has caused the brickwork to be wet - then
stained - then crumbling due to frost. (all for the sake of a tee piece.)
