SIAMP 32499910 Optima 49 Flush Valve - White

Easy to fit, if you have small hands. From receiving to removing the faulty unit and fitting the new unit took less than 15 minutes!

Very good in performance

Good product but deliver disappointed

Worth buying easier to replace than the washer

This is the replacement for a damaged flush mechanism in your cistern. Usually the part in your old cistern that goes wrong is the rubber diaphragm, which seals the water outflow so that the tank can fill after you have flushed it. When this rubber diaphragm gets old it allows the refill water to leak into the pan, therefore your cistern doesn't fill up. What you notice is that water is constantly running into the pan, and when you try to flush the cistern you find that it is empty. IMPORTANT: Lower the toilet seat before you start work - you don't want anything to get lost by falling into the pan! Fitting this new unit is simple: Undo the chromium ring that surrounds the flush button. If it is difficult to turn you can put on a pair of washing-up gloves to give your fingers better grip. Once you have undone the ring you can lift-out the flush button and lift-off the lid of the cistern. You remove the old plastic flush mechanism by grasping it AT THE BOTTOM, pressing it firmly downward and rotating it by one eighth of a turn anti-clockwise. Wiggle the old mechanism and pull it out. Wipe around the circular plastic seating in the bottom of the tank to remove any grit or other debris then insert the replacement mechanism. Push it down into place by holding it AT THE BOTTOM then twist it firmly clockwise until it is locked in place. Replace the cistern lid, gently screw-in the new flush button that comes with the plastic mechanism. Do not tighten the chromium ring too much - it just needs to be sufficiently tight to stop the flush button from moving sideways; leave the chromium ring slightly loose so that it can be undone next time without trouble. If you examine the old plastic flush mechanism you'll probably find that the black rubber diaphragm is slightly shredded around its edge. Treat the new mechanism gently as you fit it; as you can see in the photograph the top is just held by two delicate stirrups, so grasp the mechanism at the bottom when you are fitting it in place.

Very good item. Works like a dream and easy to fit if your replacing your old Siamp flush valve. No need to remove cistern, unless first time using Siamp.

Delivered with the same settings as the very old one that suddenly would not stop flushing, and includes a new flushing plunger for the top of the cistern. No need to turn of the water supply, just twist out the old fitting and twist in the new. Job done in less than one minute. It also comes with a new bottom fitting, but that requires removing the cistern to fit it. No need for that unless that was the cause of the problem. Simple.

Fabulous my dentist was impressed
