Cistern water too ferocious!

[oscar468]

I have a fairly modern push button cistern. When I press to flush, and the float arm lowers; the water splashing against the side of the inner cistern wall- at the top- has become very powerful (presumably coming from where the ball valve has opened?) and proceeds to splash over the lid and trickles down the outside of the cistern
Any ideas how to fix?

take the lid off and have a look.

The ball valve should have a plastic bridge on the top that turns the flow and directs it downwards. I expect yours has fallen off. It usually clips on and is retained by the big nut holding the edge.

Look for the service valve that turns off the water supply to the cistern in case you have to loosen the big nut to refit it.

Thanks, but can't see anything immediately apparent. I've uploaded a pic if that helps. The white part at the top right is where the water gushes out and hits the side of the inner cistern wall

Are you sure it's splashing water, not a leak at the valve body?

A Fluidmaster inlet valve, which discharges from the bottom of the pedestal below the waterline, would be an ideal cure if it isn't the valve body leaking.

the white p[lastic part on the top is the bridge. Yours is a Torbeck vavlve. Turn off the water and loosen the big nut and you will be able to pull off the bridge for inspection. The water is supposed to run through that transparent, perforated polythene pipe.

hmm..pretty sure it's flowing over the top - see new pic

Well I was watching it and the water is not flowing through the polythene pipe, definitely coming out of the side where I've indicated with the arrow in my 2nd pic

The 'bridge' (sparge pipe) is coming apart. It might be re-glueable/sealable.

if you email [email protected] they may send you a spare one free. I've found them very good with occasional bits.
