help, noisy sump

[TomStill]

Wayne and Norman came over today and helped me get my 90 gallon up and running. Thanks again to them. It has been running all day and I am noticing alot of noise coming from the drain line into the sump. We attached a piece of spa flex to the sump drain so that it would drain under water, however I am still having the problem. It is on and off. it seems that when the overflow fills up, it drains down and then fills up again. I know this is how it is supposed to work, however I feel like I am in the ocean right now, haha.

I always thought that the return pump would be the noisy component, but it is pretty quiet. Any ideas on what I can do to quiet the drain?

Thanks in advance for your help!

You need a Stockman or Durso standpipe.

I think that is what I have, isnt that what comes in most overflow kits?

Depends on the type of overflow kit that it is. All Glass "Mega-Flows" come with the Durso type, but others don't. Google the Durso and see if that is what yours looks like, also make sure yours has an air hole in the top of it to allow the air to escape. If it is a durso and does have a hole, the hole may need to get bigger. Some research on the net should fix your problem. Good Luck.

DOes one side have a large dip in the hose to the sump? Air can get reapped and then the line has to build some pressure behind it (via gravity) to clear the up swing. If that is the case, you may consider replacing the long grey accordian pipe with CPVC that is short enough for a straight run without kinks or bends and significantly reducing the amount of the loop.

is it filling and then "flushing" sounds like a toilet? how much gph is your return? I dont know your setup but sounds like you are maybe trying to push to much through your overflow. if you have a durso setup u could try enlarging the hole on the top of the durso stand pipe.

There is a design called the Hofer Gurgle buster that works to eliminate noise in overflow lines! I have had these for years now with great results. Also very cheap to make around 5.00 for pvc parts to build.

You could try throttling back the pump and see if that helps. It could just be pumping more than the overflow can handle.
