## Questions & Answers

**Q: what are the dimensions of this item**
A: All of these are pretty standard in size. This is made so that it will fit at least two different sizes. The way it came, it didn't fit, but I used scissors as instructed to cut one little piece off of it, and it fit perfectly, snapped right into place and worked like a dream. The whole thing (including going and finding a pair of scissors) took less than 5 minutes. That includes reading the instructions, too. Unless your toilet was made in another country, I'd guess there's a 99% chance that this will either fit perfectly as-is, or with a small cut with scissors, will fit perfectly. Pay attention to where the chain from the lever is fastened so you can fasten it back in the same place.

**Q: Has anybody used this flapper successfully in modern (1.6 gpf) toilets, or will it only work in old 3.5 gpf toilets?**
A: You could try it in a 1.6 GPF toilet...But it works best for 3.5 GPF toilets made before 1994. Fluidmaster  labels it as being a universal flapper. That's all I know about it. Other than it has a 5 year warranty.

**Q: I release the toilet lever it goes straight to the bottom which means that the tank doesn't fully empty.  Its predecessor floated.  What's wrong?**
A: Some flapper just do this.. I just hold the toilet flushing handle down a few minutes to be sure it is fully empty.

**Q: The fluidmaster 504 is the form I need because the toilet is old and does not have mounting ears but is it made out of rubber or plastic?**
A: Thank you for your question concerning our flapper model 504.  The flapper is an all rubber model.  For additional questions on any Fluidmaster product contact us at your earliest convenience.
