Hidden Closed Loop Intake

[mark]

Dez, have you considered a strainer used on jetted tubs or hot tubs, would stick into the tank 1/4" or less.

Finally, someone on topic. Do you have pics of any. That might be a good option. I spoke to someone recently after posting this thread who has a lot of experience and I'll probably go with his idea. However, I would still need a strainer or eggcrate, any link? Thanks Mark.

Did a quick google search but not finding a threaded or slip flat strainers but have seen them in builds. Worst case could just have the bulkhead coming into the display and get a tub strainer and hold in place with a bead of silicone. If got creative could even mount a nylon nut in the bulkhead and fasten through to it. The one in the picture is about 4" in diameter.

Also here's my 2" CL intake in the overflow with room to spare.

Mark, is that overflow noisy? Another reason fro me to have my standpipes high is to mimize the water fall noise from the overflow. Acctually, it works. Because last week, the air inlet to to durso got a little plugged with salt creep. So, the drain was siphoning, and the resultant noise from the larger overflow drop alerted me to something not right with the tank.

My closed loop intake is at the bottom of the overflow. And the drain into the sump is a Durso style. There is No reason why you cant have a Closed loop intake in an overflow

Are the closed loop inlets and outlets at the same height or higher than the overflow standpipe? I had totally convinced myself that it would drain the tank to the standpipe because the main tank is open to the overflow via the closed loop plumbing, but there must be something that is preventing this?

My closed loop inlet is bottom of overflow, the outlets are just at waters surface. OK, NOW I am seeing a possibility. IF you have a sump drain at the bottom of the overflow, AND have CL outlets mid tank or so, Yes then it will back flow through the CL outlets, into overflow, and flood the sump. But, if you place your Sump standpipes up at a height that will prevent this. Even Herbie style can use tall standpipes. Then, no matter how low in the tank the CL outputs are, the Overflow will not drain lower than the height of the standpipes.

Like anything in this hobby, Nothing is impossible, but EVERYTHING needs careful planning


Here is a pic of my overflow. You can see the CL plumbing. Pump is in bottom of Overflow. and ,my Durso drain. Water level drop is 2" approx over the overflow. Sump outlet is the Locline to the lower right, its' about 1" below the water surface, and there is a check valve on that line to top extra siphoning. I could put any of my CL outlets below the water line, But my reason fro doing the CL was to eliminate the look of outlets in the tank. So, I have kept them at the surface. next tank is hiding them in the rockwork

Would be if I ran it like this. What I did was removed the Durso then moved the standpipe over to get a picture. With everything in-place the water drops only about 1.5" into the overflow chamber.
