## Questions & Answers

**Q: hole size**
A: N/ A

**Q: I am not able to measure the brine tank but the plate we need to replace is 16 1/4" in diameter. Do you think your replacement plate would fit?**
A: This grid plate is made for the "standard" 18" diameter tank.  I think if you tried to cut-it-down, you'd reduce the rigidity of the plate itself.  There are rectangular brine tanks (11x11, or 15x17"), but this would NOT fit those either.  If you want a brine plate, you could buy a new 18" brine tank: https://www.amazon.com/Complete-Brine-Tank-Safety-Float/dp/B00AU3Q4HK/ref=sr_1_9?keywords=brine+tank&qid=1560004574&s=gateway&sr=8-9

**Q: My tank is 18" diameter but it chokes to 17" at the top opening. Is the plate flexible enough to force through the opening?**
A: It is a stiff/tough plastic, but you might be able to flex it enough to overcome the 1" difference.  You'd flex it "side-ways" then rotate it to fit the diameter of the brine tank.  Since mine is in my brine tank currently, with salt covering it, I can't really take it out and check it for flexibility.

**Q: My 18 in. Brine plate seems to have a 3 and a half in hole, not a 4. Are they just calling it a 4 but it really isn’t?**
A: The brine plate that I was replacing was part of a Kinetico water softener brine tank.  The replacement was done a while back and can't remember if the hole was 3 1/2" or 4", but it was the correct plate for my system.
