Fluidmaster Replacement Adjustable Flapper 502

Good replacement and easy to fit myself

Practically perfect in every way .

Due of the chlorine used to disinfect or water supply the flexible plastic becomes harder over time and actually shrinks, which means after about 3 to 4 years the flapper no longer seals properly. Normally water trickles past the flapper and down into the toilet bowl, or the flush never stops flushing. I have replace three of these over a period of about 12 years while the rest of the Fluidmaster stuff ( float valve, flush handle and the actual flapper seat have been fine ). I normally know our flapper needs replacing when I hear water flowing in out water system at odd times, this happens because when the flapper first starts to leak it is very slow leak, and the water level in the cistern drops very slowly until it triggers the float valve ( ballcock ) to replace the water, so you get a short whoosh of water through the house pipes - sometimes in middle of night when no water should be flowing, but the water soon shuts off. These flappers are so easy to fit it only takes a few minutes to unclip the faulty one and clip in a new one, reconnect the chain to flush lever and you are good to go. I normally keep a spare one in a safe place, which is OK because unless the flapper is immersed in chlorinated water the plastic stays lovely an flexible for a very long time. I had just fitted my spare flapper so ordered another one straight away.

Fits.

As described

so easy to install ,cheap enough not sure how long the original had been installed 5 yrs maybe.

Hard to fit. The new hinge slots too SMALL for my old unit. It can be pushed onto my large pivots but then there is too much friction too allow the flapper to FALL . Lots of water lost. So I sanded of some of the outer diameter of those old LARGE pivots using strips of wet and dry and then all worked well. The supplied extra small pivot unit was no good at all, too small to fit even if I cut of the old pivots so ignore that clamping unit.

Nothing lasts forever and this replaced my worn out one, so spot on.
