Q: I need to replace a main drain grate. It's either Swimquip or Sta-rite. The pool is 20 years old. The grate measures 7 5/8" across with the inset portion 6 5/8". It has a solid square in the middle of an eggcrate design for the holes.
A: All the old main drains have been redesigned for safety and many of them are discontinued. I
would recommend that you replace the drain cover that you have with a “universal
drain cover”. This is a cover that is designed to fit in the place of any cover
up to 10 inches in diameter. Here is the page on my site that shows the cover
that I am talking about:

Please let me know if there is anything else I can do for you.
