Frequently Asked Questions

Q. "Can these float valves work inside my steam tables?"
A. All of our float valves are really designed for cold water.

Q. "Why is the price on your #FL861 float ball so much lower than the other sizes?"
A. The 4" x 5" FL861 is a basic, standard size toilet tank ball and is produced in much higher quantities than the other sizes. In addition, it is not approved for use in potable water applications, so is not made to conform to those requirements.
