## Questions & Answers

**Q: Does the Korky 818BP match up/replace the Kohler 85406 flush valve?**
A: According to Korky's website: "It has a universal design to fit all brands and features a wide range of adjustability to fit most 2-piece and 1-piece toilets. Designed to fit more toilets, the QuietFill toilet fill valve adjusts from 7-3/4 inch to 13-1/2 inch."

**Q: if this is a prime item, why is the delivery date a month away?**
A: Go to Lowes or Home depot...in stock and grab a Starbucks double express :-) on the way...

**Q: When I connect to the water supply line, the connection is loose, and water leaks out. Is the connection point on the Korky supposed to be empty?**
A: The red gasket at the bottom should be inside the tank, the large nut is then installed hand tight and then snugged a bit more but not too tight.  if you do this, there is no way that water can leak out of the tank at that point, unless the tank is cracked.

**Q: Is this fill valve by Korky superior to that of Fluidmaster (as in durability and preveting toilet leak)?**
A: The valves we were sent did NOT have the gasket on the bottom included. Was not noticed at first, why would we think it didn’t have needed parts. Put in and leaked everywhere!  Finally figured out why. So just be aware of that.
