I wasn't quite sure which topic to post this under but I work in commercial pools. And I have 18 of the Neptune Benson Flat Grate, Size: 18 Inch x 18 Inch, White.... Main drains that need to be replaced due to lost main drain certifications. They were installed in 2019, so they would have to be replaced after next year anyway. I guess my question is there any direct swap for the top grate? Notice in the picture that the screw is offset from the corner and almost every other Neptune Benson, the screw hole is in the corner. I'm aware of Neptune Benson buying out Lawson.. I'm just wondering if there's a solution here other than drain the pools and reinstall main drains from the get-go. This is for a city inspection purposes. And obviously this community wants the pools open and up to code ASAP since the pool's got shut down because of it.
