Ideal standard toilet

[tomsim]

Is this an ideal standard toilet has a 2inch Gerbit flush valve. Need to do a cistern rebuild. Just wondering if will be the circular donut washer. Thanks

The normal Ideal doughnut is more like a very large O ring fits in a recess on pan.

Geberit own Twyford now, so unless it’s a Geberit, I’d wager it being Twyford.

Thanks is this toilet likely to have a recess in the pan? Or not if not ideal. Possibly just a 2.inch foam donut then

It's sort of semi concealed like the ideal ones

If it's a semi-concealed cistern like that, the doughnut usually sits in the moulded recess on the underside of the cistern rather than the pan - the flush valve clamps down through it. Just match the washer to the valve you've got fitted and you'll be fine.

So I swapped the flush valve washer and water still ran into the pan. It isn't the fill valve as this shut off ok and well below the over flow line. Would it be ok to undo bolts split the cistern and fit a new flush valve, fill valve, toilet bolts and donut washer? Thanks

Yes, the best way to get a long term fix.
