Help Red Sea Max S400 Sump Upgrade

Gonzo74 · Feb 8, 2020

I am trying to hard plumb a larger Sump from my display to my basement.

Everything is ran and ready to go but when I went to connect the the 1 inch PVC, I noticed that the Red Sea PVC is metric. Nothing I find at hanrdware stores is looking like a good fit.

Has anyone done this and if so, what did you use for both overflows and return?

Any info or links will be greatly appreciated.

You're going to need 1 of these for each of your drain and return tubes.

At least this is what I have found via other threads as I am in the process of hard plumbing my red sea tank and will be using 1" plumbing as well.
