I finally got the plumbing sorted out and everything is working! It still has fresh water in it but I figured out the kinks in the plumbing and now have flowing water and no leaks.
I have the sump levels figured out and marked.
The return pump is a little noisier than I had hoped. I forsee a replacement in the not-too distant future,
I have a question about the noise from the overflow. I dont think the wife will like the constant splashing noise. How do I quieten it down?
