rocca close coupled european cistern

[jasper131]

my daughter has a rocca close coupled push flush cistern with two button at the top, she had a problem whereby it kept flushing into the pan as if not shutting off properly, i have never had dealings with this type of plastic arrangement before, the water supply is separate from the syphon/flushing part i have taken it apart and cleaned the washer at the bottom of the syphon flushing part and re assembled the cistern fills ok, but at time still dribbles into the pan as if not shutting off properly i can see nothing evident that would cause this , it is more of a annoying problem than anything else, any ideas

Its not overflowing is it? they have a built in overflow that dribble back into the pan

Other than that how long has it been in the straw type plungers from the push button maybe a tad too long

I`ve had a few of these with rocca, the seal on the bottom doesn`t seat correctly, i just take the lot out and replace it with a new flushing mechanism.
