Need help urgently

[Weicowireman]

Hey Guys,
I have a brand new marine land 93 gallon perfecto. I have a sump made by custom king a Jabeo dct6000 return pump.

The level in the overflow is going up and down almost like a surge. The sump level is not fluctuating nor is the tank level. The water level in the overflow rises then lowers to the hole on the elbow gets air then goes back up. I cannot figure this out. I dialed the pump down to level 1 but no change. Am I missing something here?

Yor say brand new let it run for a few days and then look at it. Do you have any valve on the overflow, any restrictions. Or could be breakin bs.

No restrictions or valves.

sounds like its going into a syphon. their should be an air inlet on top of over flow down spout. if not then drill a tiny hole.

 

[Weicowireman]

There is a little hole up top on the drain with a little tube sticking out.

try removing the tube, you might need a bigger hole.

What edd said you can remove the tube (its glued in) and progressively drill bigger holes. Or if its not glued try pulling it in or pushing it out to change the air mix.

 

[Weicowireman]

I will pull the tube out and hopefully it takes care of it. Thanks for the quick replies...

when you increased the flow did it do the same thing?

The tube is to get the overflow to run quiet, so the water doesn't go up and down like that and sound like a toilet flushing. Move the tube up or down in 1/2" increments,, give it a few minutes until you find the sweet spot for a steady flow. Change the pump speed and you'll need to find the new sweet spot.

Taking the tube out may stop the water from going up and down like that, but it won't be nearly as quiet as if you take the time to dial in the tube to let in just the right amount of air

Make sure tube is snug. Water could be passing by

I pulled the little tube out completely. It somewhat leveled off now. Little bit of movement but not much. My return pump is dialed back to the first speed.

You don't need the air valve , if you're willing to take a lil time to find the sweet spot as described in my last post, and it's a good idea to leave the end of the tube that sucks air in, in the overflow box above the waterline, so if the water rises for some reason the tube gets blocked with water and will cause it to flush down much faster avoiding a flood

 

[Weicowireman]

I adjusted the pump and pretty sure I found its sweet spot. It's holding steady. I straightened my return pump line and found the coupling was tight and slightly spewing in the sump. I noticed the water movement on top of the water by the pump. Fixed that and so far so good. Time for a heater, salt then sand and rock. Moving along. Thank you everyone for your assistance. Stay tuned to my tank thread. Cool things are coming to Weicowiremans cube...

Install a gate valve on the return from the overflow to the sump and control it the water level in the overflow like that.

Unless there is a second drain pipe, I don't recommend putting any restriction on the only overflow drain to the sump...

Agree 100%

Also, to op, you probably want your dc6000 on 2nd or third speed to get about 500gph going through your sump at 4 to 5 foot of head pressure.

what helped me was use a larger drain pipe. I went with 1 1/4 plumbing. stopped the gurgling immediately
