How to Quiet Durso Stand Pipe Overflow

[24gnanonewbie]

The drain on my new tank is gurgling and bubbling in the sump. How do I quiet that down? Its a durso stand pipe in the overflow.

Any help would be appreciated!

is there a small breather hole in the cap on top?

is this a new set up or been running awhile? if it has been up and running a while. sometimes the little hole gets salt creep built up. use a toothpick to clean it out some.

There is a hole on the cap.

This is a new setup. Its been running about a week. I am getting a ton of salt creep in my sump due to all the air entering from the drain line.

You need to reduce the return flow. What size tank and what return pump?

 

[24gnanonewbie]

Its a 35 gallon tank. Have a Sicce Syncra 3.0 return pump with about 4'6" feet of head.

1" drain?

What is the maximum gph from that pump. May want to dial it back until gurgling stops.

Remember, tank circulation should not be driven by the return pump.

Thats a lot of pump for such a small tank....... but depending you can stick a peice of airline tubing down the hole of the muffler. ... and the tank needs a break in period to get a slime coat to be less noisy.

I bet you need to slow drain, not return.

1 1/4" drain line

At about 4'6" of head the box says around 550gph

I read about putting a valve on the drain line, but that scares me... because I have one drain line period, no emergency overflow.

I tried to put a felt filter sock, and would just fill up and overflow. Is that an indicator I need to slow the return? Maybe split the drain into two filter socks?

Gate or ball valve drain and slow it

Put a valve on the return line, reducing the flow to your tank. Since less water will be going up, less water will be coming down. I'm a firm believer that your drain should always be capable of flowing more water than your return is capable of delivering.

I had the same issue. Built a reverse durso on the drain into the sump and that took care of it!

Cool idea. Do you have a durso on top as well?

 

[Twiegs]

Yes. Pretty much made it silent.
