Toilet, Toilet, Toilet

That's my new set up overflow boxes sound like!

I had a 110g with the two boxes and used flexible hose (like form hot tub). and the gurgle buster.

However, I since upgraded to a 220g and I plumbed it with pvc.

It sounds like 10 toilets flushing NONSTOP.

I looked at Herbies suggestion (basically let the water in the pvc backfill so that the water drain doesn't drop so far.

Any other ideas!!???

I had a lot of noise on my 150---and where the bulkheads are, I put a Tee to allow air in the system at that point. It really helped the noise.

How much flow do you have going thru the sump?
Is the sump in a basement, under the cabinet or somewhere else?

You might google Durso and Stockman standpipes.
