Sump Overflow Help Please !!!

[ash9965]

Ok so I finally got my sump installed last night only here is the problem The corner overflow is draining faster than the pump can send it back up to the tank... Thanks in advance for any advice on this... Here are the details

65 Gallon Tank with corner overflow
eshopps Sump
Deep Blue Triton Pump 850 GPH
Note the sump isn't overflowing its just the corner overflow stays empty because it is draining so intensely fast
What am I doing wrong ??
Thanks again

Increasing the height of the drain pipe should help.
Can you also post a picture of the drain?

 

[AZDesertRat]

The pump and overflow should balance out. The pump will determine how fast the overflow drains.
Do you have a standpipe in the overflow to maintain the level in the overflow box?
Photos of your setup would help everyone with more informed suggestions.

A lot of people install gate valve to control the drain speed also to control the noise while water return back to the sump.

Like stated above your overflow will never flow faster than your return pump since that is the deciding factor how much water is flowing. Pics of your setup or a description will help us figure this out greatly

Only install a gate valve on your drain if you are running a bean animal style drain to control the full siphon. Other than that never use one on a drain

Your problem is not enough water. Add water!

ok to answer a few
unfortunately not at home now but here is the best way to describe it , Its a 65 Gallon tank with a corner overflow. There is plenty of water in the sump almost overflowing due to the rate the overflow is draining into the sump I have tried putting my thumb in the drain hose to allow the overflow to fill up and as soon as I take my thumb out the level in the corner overflow drops to the bottom quicker than the pump can pump it out .

here is the style of tank

As Bob mentioned, you may not have enough water.
With the pump off, make sure the display tank level is right at the bottom of the teeth on the overflow box and your sump is about 1/2 full. Start the pump and watch the levels change. The display should rise maybe half the height of the overflow box teeth and the sump level will drop some. Depending on the size of the display and sump these levels will vary but this should be a good starting point that will not flood.
What are the display and sump volume?

 

[hybridazn]

Drain some water out of the entire system until the water level in the sump is where you want it

 

[AZDesertRat]

You don't have a standpipe in the overflow box do you? That is your issue. With a standpipe the level in the overflow will only drop to the standpipe inlet.

I'm assuming that it's in the lowest it can go which is what is causing the sump to be full of water. I believe simply removing some water will solve this problem from the sounds of it

 

[AZDesertRat]

When he says the level in the overflow box drops to the bottom that tells me there isn't a standpipe? Bottom of what might tell us better and photos would nail it.

your overflow should be higher and determine the water level in the tank. Once the water level drains to the top of the overflow, no more water should flow.
FWIW three adjustments for any sump setup:

1) no flood with power out. (top tank will drain then stop before bottom floods).

2) normal operation returns when the power comes back.

3) with a drain failure (blockage, siphon break, etc) the display should not flood. sump runs out or water before top floods.

you might post come pictures so we can help more, but in the meantime lookup durso stand pipes.

yes there is no pipe just a bulkhead in the very bottom that has a hose connected draining into the sump. how can I correct. Thanks

True, this would also be insanely loud if it doesn't have a standpipe

@ash9965 did you purchase the drain pipe kit with the tank as well?

This is what it should look like in the overflow.

As you noted you don't have this?
Was this a used tank?

Simple solution is just run a pipe through the bulkhead up to where you want the water level in the tank. (like a inch or two below the tank top). While it can get more complicated with a durso and so on but that is the main thing. During power outage the level will fall to the top of the pipe and then stop draining.

Research Durso or better yet Stockman DIY standpipe designs. Both are simple to construct with $3 in PVC parts. I have found the Stockman to be much quieter, especially with a piece of airline tubing in the cap on top and fine tuned.
