## Questions & Answers

**Q: How do you tell which size you need?**
A: I just looked at it on amazon and because I have two toilets with these fitted it just looked right.
I did not know they came in sizes, I have changed one before, but got the whole unit just to get the flapper valve.
I was pleased when I saw amazon did just the flapper valve and half price of whole unit.
Sorry I cannot be any more help. It does say on the package that it is for 2" flapper units.

**Q: my old one is 2.5 inches across. Is this the same size please?**
A: The one I have is slightly bigger at 2.75 inches across but that shouldn't be a problem.

**Q: My toilets very old, pull chain type. Would this be the right one to buy?**
A: Agree with Fred’s comments. It would be a good modification to swap out the entire unit, but depending on the age of your high level cistern the whole down-pipe may also need changing as these were often lead jointed. Unless you are really good at plumbing, this is a job for a plumber.
