Durso

JMorris271 · 09/20/2014, 07:22 PM

Hi . I am doing a really quick setup to hold things over until I get my tank going. Quick question. Is the top of the durso crook suppose to be above or below tank level? Thanks

Water level I meant. I have never done this before and this forum is my only resource for information. Please help out here.

If you are speaking about standpipe cap with the hole - Above the line.

No. Not the straight up with the cap . The candy cane looking version with the hole in the crook. Is water suppose to cover that top hole?

Maybe the link will help. I am not quite clear on the part you are talking about. I run durso's on my tank. The "Crook" part the water goes into is about 3/4 submerged on mine. I do not have a hole drilled in that part just the very top cap part.

Bottom turn of the elbows will determine water height.

My durso stand pipe. Ignore where it is hanging in the photo. I was using it for something else

I don't have a vertical pipe running up with a cap on it. Mine is composed with 2 45's

Wow that looks like the water would trickle out of that hole.

I'm sure it would. The pipe was jut posing so you could see it had holes. But thanks for responding.

What is the purpose of the hole in the down turned ell? For the record...that's two 90 degree ells. Two 45's equals 90 degrees. :-)

When I had mine running like that, my water level in the overflow ran just above that 1/2 inch hole in the crook. That setup gets loud and flushes if you try pushing anymore than 300gph.

I am glad someone stays on top of things.

Just guessing it's a siphon breaker. Not completely sure. Maybe someone else will clear it up.

I don't like the looks of that and wouldn't run it on my tank. The design of the Durso should always have air allowed in the drain. The ideal setup would have an end cap at the top with an air hole and a strainer on the bottom facing intake. A snail or anything covering that hole would create a full siphon. Which could send too much water to your sump and possibly flood. Another flaw with the Durso is the air hole must be periodically cleaned as salt creep will build and limit air flow, again to the point of creating a full siphon.

If you want a full siphon then you need a second emergency drain. Which then the whole system would become a Herbie drain system.

Set it up herbie. Much quiter and will move some water at full siphon. I'm a idiot at handyman stuff and if your tank allows I would just take those 90s off and go herbie

It's probably two holes, one on either side designed to ensure the pipe does not air lock. The overflow kits that I got with my marineland RR tank look just like with one exception being an air vent hole on the top.
