## Questions & Answers

**Q: will this fit an one piece toilet with a 3" drain?**
A: it should.  I have one in each of my 5 toilets and they work wonderfully

**Q: hydrostop has an adjustable slide on the back numbered 1 to 7. Can find no info on adjustments. Anybody know what the slide does?**
A: I don't see any information on it either.  I didn't notice it before.  I just checked the adjustment and it seems to change how quickly the water exits the tank.  It didn't change how much water it released on my toilet but that may be another thing it adjusts.

**Q: In the pictures, the flush handle is on the front of the tank. Mine is on the left side of the tank. Is the cord long enough for this application?**
A: Thank you for your inquiry. It will depend on the distance from the flush valve location in your toilet to the side where handle is located. The cable cord on the handle is approximately 10-1/2 inches long.

**Q: The handle broke off but everything else works. How do I get just the handle?**
A: Contact the company as it is warranted
