## Questions & Answers

**Q: my tank is 10.5" deep.  I understand the expander kit will work for the width of my toilet, but how deep is it?**
A: Hi.  The expander kit sits on top of the toilet tank.  At most it is possibly 1/8"-1/4" thick.  It does not go IN to the tank but lays ON TOP of the tank.  Hope this helps.
