Rated 5 out of 5 by from Great choice I wen into my Screwfix branch having already researched online. I got 3 out and this unit was simply the best. Got it to the job and it couldn't have been any better. Once spaced out and trimmed the fitting was a doddle. Would buy again or definitely this manufacturer.

Rated 5 out of 5 by from Good fit and does the job Needed new one in cistern, used these before, great design and do the job. Have to drain old this time. What we like about this design is next time can undo top bit. Then leaving white pipe in, just disconnect the blue section and put new section on. This will save time for future repairs, as won’t have to drain down next time. Fills faster than the old one, with bigger flush, so clears better!

Rated 4 out of 5 by from Siphon More expensive than the rest but better quality with the ability to service without having to remove / drain the cistern. Instructions were a bit short & sweet but sorted quick enough. As usual, Screwfix great service over bank holiday weekend !

Rated 1 out of 5 by from Missing info. in Specification Once installed, I cannot pull out the yellow plastic pins that fixes the white part of the siphon to the blue part of the siphon because there is not enough room in my cistern to pull the yellow pins out. The specification should state what the minimum internal dimensions of the cistern should be. It's not good enough to simply advertise as "Fits most lever-operated cisterns" - what exactly does that mean ? e.g. does it mean that it fits 50.1% of lever-operated cisterns ? If so, then that means it does NOT fit 49.9% of lever-operated cisterns, which isn't very helpful. The next time I need to replace the diaphragm, I will have to disconnect the water supply and dismantle the cistern again !!! The whole point of this product is to save time having to disconnect the water supply and dismantle the cistern !!!

Is this compatible with the Thomas Dudley Ltd Acclaim Side-Inlet Dual-Flush Lever Cistern 9Ltr (4047F) please

Asked by: Beermad

Does this require a float valve as well or is it built In?

Asked by: Karlb23
Thank you for your enquiry. This item flushes the cistern, if you require an inlet valve that lets the water in. You will need to purchase this also separately, if your old one is not working If you have any further questions, please contact us on 0121 530 7000 Kindest Regards TYDE Customer Service Team
