I am installing an external pump next weekend. I have Bio-Fil 1 sump rated for up to 180 gals. I need to know the size of the drain before I tear it all down.

Any one know who makes this sump or the size of the drain? I can not find anything about it on the internet. I can not get to that side of the sump until I drain it.

Thanks

I found the answer, its a 1 1/4 fitting.
