Easy replacement
Bought as exact replacement for broken flush valve. Simple to fit; 1: remove old unit by pressing clips on each side near base. 2) adjust small flush capacity cup position to match the old unit. 3) Click the new unit into place. Turn water off/on before/after, or tie up fill valve float. Works perfectly

Brilliant direct replacement for 20 year old cistern
Really surprised to find this on Amazon as it is a direct, same manufacturer, replacement for the flush valve that has finally gone on our 20 year old Vernon Tutbury cistern. If you are happy with a bit of DIY it is really easy to do. You need no plumber and I didn't even bother to turn off the water though that is probably recommended for peace of mind. Mine came with no instructions but there are YouTube videos that show how to install it if you look.

Direct replacement - solved the leak. Good price.
Excellent product! Direct inlet valve replacement and perfect fit. Resolved the constant loss of water from the toilet cistern and constant dripping of water into the toilet bowl. Easy to fit with the two clips/lugs.

If your cistern still fills OK but just fails to flush, you can save money and just replace the flush valve...
Fitted tall Galassia cistern no problem. Watched online videos from two plumbers who suggested there was no point attempting to repair a broken flush valve (it does seem to contain numerous fragile joints and moving parts) so this did the trick. NB - this is *just* the flush valve (including the critical lower seal) which will snap onto the bottom cistern fitting which typically will be sound and won't have broken. You will reuse your fill valve and overflow and avoid buying the whole £50 - £70 kit quoted me from two local plumbers' merchants. Space was very tight for the install and the old one was tricky to extract as the cistern was narrow. I managed it by rotating the old flush valve so that one of the two lower snap-on tab/grippers was in a clear space location in the cistern and then squeezed this whilst lifting and rotating the unit until the tab/grip from the other side comes round into the clear space for grabbing and squeezing. Hopefully you can then wiggle/extract, swap out and celebrate. The new unit simply clicks into place and voila, flushing toilet. A great joy to all the family.

Produit acheté pour remplacer le précédent, qui a défailli après 22 ans d'utilisation Le produit est rigoureusement identique à l'original, exceptée la couleur de certains éléments. L'installation a été rapide et le fonctionnement est maintenant impeccable. La partie céramique de mon réservoir d'eau est de la marque Roca.

Excellent product! This replacement fits exactly like the old one. The flush mechanism also works flawlessly. The only difference is that the green button is now blue.
