I have a push button toilet and quite regularlty there is a stream of water that runs right down the middle of the toilet?
This stream of water is pretty contstant and I have tried tightening bolts leading from the toilet, flushing the toilet a few times to get this stream to stop and after a while it does only for it to start up again.
I assume this is pretty much a leak and will be costing me money is waste water, so I want to get this fixed asap.
it sounds like the cistern infill valve is not cutting off. Back int'day, toilets used to have an extra external pipe that took overflow out through the wall into the drain - now cisterns have this built in, so if your cistern is over-filling then the excess water drains into the toilet bowl.
The regulator of he infill valve needs to be altered. This is usually a screw-like plastic gubbins on one side of the inside workings of the cistern.
If you don't feel confident about takig the lid off the cistern, bear in mind that this is a five-minute job so don't let anyone overcharge you to do it.
sounds like overflow needs adjusting,simply unscrew metal ring around push button-may be tight but persevere it wont break-then adjust valve or ballcock on inside until flow stops before it reaches top of outlet pipe.hope thats helpful.I recently moved and inherited one of these pushbutton types for the first time and embarrassingly had to ask nephew for help tto open cistern to insert my usual blue flush LOL so simple when you see it done!
If the push button is on top of the lid: raise the lid slightly and you will see that a length of plastic tube is attached to the lid and goes into the 'works'. This is of sufficient length to allow you to raise the lid like a box lid, disconnect the plastic tube from the button mechanism (it kind of clicks on and clicks off again) so you can then place the lid safely to one side and fiddle with the screw-doojit like Tommy suggests.
thanks for asking that huggins, i've had one of these push button things for a year and have failed to see a way of getting the top off, so have had one of those freshener things in a little basket hanging on the edge of the loo, and i hate them, now i can put a blue block in at last.
I had the same problem though afte it was taking ages to fill and after the push flush started playing up. I had to pull the top away (was grouted, or whatever they use, on). The flush mechanism was knackered and replaced but I still find if the tuby thing which is let up and down to let the water to flush through doesn't sit back in place properly to shut the water off then it will keep streaming down. Usually a bit of a nudge to the top of the loo seems to make sure it's back in place (the plumber the landlord got didn't grout it back in place so still moveable).
At least I can put block fresheners in the top now though (as no rim to attach that kind to).
