I really need help. (Hopefully with a Herbie style drain)

[mark]

the rising and lowering in the overflow indicates that the Durso is not tuned and would be getting some surging of air.

The negative with the Durso though is you'll always get air in the line back to the sump (not with a Herbie).

The first thing I would try is a 2" standpipe. It'll be the quickest and easiest fix and give a better idea where the problem lies.
Another idea would be to install a Tee directly below the bulkhead and run the branch line up and then down into another section in the sump. Next install a valve just above the sump on the main drain line. Closing the valve will cause the drain to fill with water stopping air from entering the sump. You'll want to adjust the valve so water just starts to trickle out the other drain and the back up the valve a tiny bit. This will work similar to a herbie overflow but only needs one drain, it won't be as quiet as you'll get noise through the second drain line as it's connected to the main but you should be able to muffle it.

Thanks for all your ideas. I'll try some of them out this weekend.

My tank makes a huge amount of noise but if I tune it just right there is no noise. I have a 1-1/2" pipe with a basket. The thing though is I have a piece of airline zapstraped to that and just adjust it up or down to make the noise stop. If for some reason the hose clogs. (I keep it at the max height I want the tank to ever be) then the water gets sucked right down fast with tons of noise alerting me that there is a problem.
Hope that makes sense.
Maybe a small piece of hose is all you need.

sphelps, didn't you have a drawing of that and if so could you post it up again

I think he means something like this??

Looks like I could try it one of 2 ways.

First I could put a piece of 1/4" hose on the top, but how do you attach 1/4" hose to a piece of 1 1/2" PVC pipe so that it is adjustable? This sounds like it could be the simplest cure.

Secondly I could turn my 1 1/2" drain into a "Herbie" with a gate valve and use one of the return holes for the emergency drain, leaving me with one hole for returns. The tank currently has 1 - 2 3/4" hole for 1 1/2" drain and 2 - 1 3/4" holes for 1" returns.

I'm not sure I understand why one needs an emergency drain for the Herbie style, but not for the Durso.

Oh my, sometimes I wonder why I started this? (Just silently venting)

Sorry, but can someone put some words to this picture for me.

Great idea I would try this on mine but I don't have enough room for that now.
