Pentair FNS. Plus 36 filter drain plug blows out

[Tylerb1991]

I have a Pentair fns plus 36 DE filter. The other night the bottom drain plug was laying on the ground and water pouring out. I got a new plug and when the pump is turned on it’s blowing it out. I believe the threads are stripped on the bottom tank assembly. I’m trying to find a used replacement bottom tank. Is a clean and clear plus bottom tank compatible with my fns plus lid and filter grid.

FNS 36 tank bottom is available for about same price as the other and has the proper plumbing.
