Review: Fitted perfectly - I have recently moved to a new property and the toilet cistern was not working correctly. It never stopped filling! I disassembled it and found the defective part. The diaphragm on my original part had perished and failed to seal the valve. Searching the internet I finally found the part required. This was exactly the part and it came complete with the plastic insert. Five minutes later I had it fitted and the cisten now works correctly. Great product. Thanks
Review: Cheap and easy fix - My toilet was overrunning and sending water down into the bowl after it filled. It did this for a while and then stopped. I checked the old washer and it wasn't visibly damaged but I thought I'd try replacing it anyway because doing that is a whole lot easier and cheaper than replacing the whole float valve. Fortunately the fix worked and the toilet is now back to normal. The part is about half the price here compared to the local DIY shops and arrived the next day so I'm happy with that. The previous washer (which I bought from elsewhere) was only a year old when it broke though so I hope this one lasts longer.

### ⭐⭐⭐⭐ Solved a leaking cistern problem
*by O***D on 21 August 2022*

Simple product that solved a leaking cistern. Initially, I simply cleaned up the limescale on the original washer and cistern part, and didn't replace it. That worked for about a year, and so I ended up using the new replacement. Solved the problem completely. Dead easy to remove the old and fit the new.
