Toilet water level

square_bear

Hi all,
I wonder if anyone can help.
For the pst two weeks the water level in the bottom of my toilet pan gets very low.
When I flush the toilet the level is normal, but later on the level drops.
I cant see any leaks anywhere.
Whats happening?

Thanks for any help.

different pressures within the house compared to outside due to the weather probably

also wind getting into the waste pipe can 'slosh' the water in the pan and lead to it lowering a bit

Hi

Ground floor wc or first floor?
Ground floor = possible blocked drain , check manhole .
First floor = possibly something 'wicking' the water out.

Had this in our downstairs loo a couple of weeks ago. Turned out to be a blocked drain, as Canucklehead says. Actually it turned out to be the sewer under the road that had a blockage, so the water board came and cleared it for free

How can a blocked sewer cause more water to drain away than usual?

We had a blocked sewer once and it caused the water in the toilet to NOT flush away. I seem to remember the workman saying something about water can't go through a blocked sewer, so it backs up into the bowl.

If this is happening in a downstairs toilet and you have an upstairs one on the same downpipe, then flushing the upstairs one could siphon water out of the downstairs bowl.

Not blocked fully but partly. the restriction causes the water to syphon out of the pan when flushed, whereas normally air in the unrestricted larger pipe would stop syphoning. A sign of this being a problem is that when flushing the pan tends to fill to a higher level than normal, then drops to a lower level than is usual on emptying. Strange but true.;)

Thanks everyone.
The problem has sorted itself out.
I left it a couple of days and whatever was blocking it must have been cleared.

Hi

Sorry to be a bit gloomy but we had a loo doing the same thing and it turned out that the pipe underneath was coming loose and the eventually came apart (pouring water onto the room downstairs)

Luckily for us it was a suspended ceiling so didn't do too much damage

We had this problem recently, have had 2 new tiolets installed, the downstairs pan had a small leak and had leaked all underneath my flooring. not a nice smell and i had been blaming the mess on my 6 year old son.
Seems to be ok now, and i did say sorry to him lol
