Reviews
Thomas Dudley Niagra Mechanical DualFlush Flush Valve is rated 4.7 out of 5 by 36.
Rated 5 out of 5 by from Good quality replacement flush valve Seems good quality and works well. Easy to adjust and set up both the overflow and the flush volume. Just remember when measuring the height that it is the cistern and the lid. If you measure just the cistern, then you will cut the rods too short

Rated 4 out of 5 by from The 'Curate's egg' of flush valves Very good in the lower parts. Sturdy construction, and a valve seal and seat that is a cut above the normal floppy big silicone washer varieties. Looks like it will last and be easy to clean. The part flush adjustable cup mechanism is simple, robust and easy to adjust. The outlet washer looks a trifle thinner than normal but sealed fine when done up tightly. Flush produces a good volume of water, rapidly delivered. But the gubbins above the flush buttons is a queer rickety assembly that seems to be trying to solve a strange non-existent problem. It makes the flush button assembly perched above it impossible to fix down really tightly because it's perched above all the wobbly plastic, with the instructions urging you not to 'overtighten' the fixing screw. The push buttons look cheap and flimsy. In the end, I chucked it all away as the weird spidery retaining mechanism easily unclips from the top of the valve, and installed a standard push button/push rod fitting. This locked down firmly and satisfyingly with the usual ring-nut type fixing - no more wobbly buttons!
