Stockman Standpipe - Help to Build

[newsalt]

I was wondering if someone could help me. I'm in the process of setting up a 120 gallon tank. The back wall of the tank has a 1-1/4" bulkhead fitting which is inside a DIY internal overflow. The overflow box dimensions are 10" wide x 6" deep x 12" tall .I'm having two problems.

First: The water level in the overflow box is too low which causes the water falling into the overflow box to make alot of noise.

Second: When I turn off the return pump and restart it, the water rises in the display tank and overflow all the way up to the top rim of the tank just shy of spilling over and then the level drops.

I want to build a Stockman or Durso type device to help with both problems, but I'm not sure how to build it. I know what components I need, but I'm not sure how tall it needs to be, or what pipe size to use. The photos I attached are a view of the overflow from the back, and a picture showing the water drop into the overflow.



Can someone help?

I looked at the site. Unless I'm missing something, It doesn't really tell you how tall to make the standpipe or how to modify the design if the bulkhead is in the side of the tank like mine rather than the bottom of the tank.

I think a Durso would be better for that setup. Make it so the "T" is on the outside and the street El is on the inside.

I'd agree with sjm817 (as I oftentimes do) that you'd be better off with the Durso Standpipes. The Stockman's are primarily for hang-on overflows and are used because of the more limited room available in those than in the kind of built-in overflows that you have. Here's the details for construction:

Try the Hofer Gurgle Buster, I have been using them for the past two years and they are completely silent.

Here is a link to my version of the Stockman standpipe. I have a very similar overflow to yours and this is working great.

That looks interesting. I'm going to read through that whole thread. Thanks.

I may be wrong but I don't believe Herbie's method will work for you because it requires a second hole to act as an emergency overflow. I checked it out when setting up my tank and I did not want to drill another hole.

You're right. I started to read the thread and it say that it will only work in systems with two bulkheads. Oh well.

True. IF you size your sump so that your display tank can hold the water in the event of a drain clog (where your sump gets pumped dry as all of it's water is pumped up to the display), then you are not risking a flood, just risking running your sump pump dry.

pay attention to this though

"Note from Ken Stockman: I have redesigned the water intake on the small pipe ( where the water exits). Instead of drilled holes I used a miter saw to cut a 1 inch square hole in the pipe. This will stop small pieces of debris from getting stuck in the pipe intake."

Stockman needs a vertical drain. He has a horizontal drain hole. How would you install it?

with a 90 degree elbow

 

[AZDesertRat]

Just put a 90 degree elbow inside the overflow facing up and stick the Stockman in it. I built mine so the overall height is about 1.5" below the top of the overflow and its totally silent.

 

[sjm817]

Yeah, you are right...(doh!) but...I think a Durso would work a lot better for that configuration. That is the setup I always see used for an external drain.

 

[jpslickorocks]

now that I look at the pic a little closer I think i would do a durso instead of a stockman. Put a 90 degree elbow inside of the tank pointing up so you can mount the durso.
