## 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.

### ⭐⭐⭐⭐⭐ Solved my salt mushing problem
*by A***. on June 19, 2020*

Fit my 18 inch diameter salt tank. My softener was shipped without a grid. Had frequent salt mushing at the bottom that clogged the intake from the brine tube. Tried every premium salt brand with no luck. This was the fix. It keeps the salt above the floor of the tank. Snug enough around the outer edges to prevent salt from migrating past the grid. The 4 inch brine tube hole was not as snug. Could feel salt pellets falling past the grid onto the bottom of the tank. Bought a 3inch rain collar roof vent boot at the local hardware and slid it down over the brine tube to contact the grid plate and seal the gap. The weight of the salt keeps it tight against the grid and keeps the salt pellets from falling through. Works great now. No more clogging,mushy salt to clean out. Wish I had installed this sooner.
