Toilet Cistern Flush Valve jamming

[rieverjohn]

The cisterns in my toilets have the pictured flush valves fitted, the body of the assembly can be removed by twisting it counterclockwise by about fifteen degrees and lift out to replace the seal at the bottom, easy peasy, one of the valves has jammed open a couple of times no apparent fault and the locating pegs seem OK. I can't find a replacement assembly anywhere on line. does anyone recognise the make and know where I could buy one please.

Can you grease it a bit?

Looks similar to an Ideal Standard or one of these. Do you know the make of your toilet/cistern?

Hi Loofah, thanks for the suggestion but I think grease inside a plastic assembly would harden in cold water and make the problem worse.

Thanks for your reply too Chris(CBW), It does appear to be an Ideal Standard fitting but modified enough to need a complete replacement, need to find the right height. I'm not as young and fit as I once was so may need a plumber to fit it.
Can't find any info as to the make of toilet or cistern.

Silicone grease is the suggestion to use I suspect.
Water repellent and doesn't go hard or sticky at normal water temperatures.

You need to remove and take pictures of it out from multiple angles to compare to ones on sale. Or take to a friendly local plumbers merchants to get a match.

Some makes are adjustable height and come with multiple bases to suit the flush pipe installed. (e.g the Siamp Optima's that are fitted in my cisterns).

Yup, I should have specified

Thanks again Rodders and Loofah. I'm barred from driving temporarily after a stroke and repair operation but showing it for comparison seems the next move.
