This is useless the bottom flange for sealing is too small, you have to place it very carefully in the middle of the hole, took 3 attempts. The small flush is no flush, once you remove the bungs they will not reseal a real pain the backside, don’t buy this rubbish.

Just a ‘bog’ standard cascade flush replacement. If it lasts 20 years like the existing Thomas Dudley I’ll be very pleased

Unfortunately the siphon was faulty, so didn’t flush when installed. Tool station staff were very helpful and suggested a flomasta replacement, which worked a treat

Replacement complete with all seals and fittings good quality

Does the job well though took a bit of work as a DIYer. Flush is strong. The instructions said to hand tighten the securing nut, which wasn't tight enough and a drip leak formed. Had to re-tighten with a spanner but no problems since. I can't figure out how to work the half-flush that it supposedly does if you hold the flush handle down. But for the price it's great.

Item in well sealed package with all required parts (I don’t like loose items as parts maybe missing ) . Easy to install, plastic maybe a bit flimsy but inline with money paid. Satisfied with the purchase.

Unfortunately TS only stock one height of these making it difficult to get the right one. Quite compact for a syphon made it possible for me to fit a more modern fill valve. Lever link too short in my case. Had to use old one. Not an in place serviceable item. Have not managed to get dual flush to work. Very responsive helpful support from Thomas Dudley to queries.
