I have had my durso in the tank for over 2 years. Never had any issues with it. Now, the past few weeks, it is making some strange noises. Not like the flushing or gurgling you would expect, but a sound like someone tapping a kettle drum with the reverbrations and everything. It is really LOUD at times and at other times not so much, but still there.

I shut my pumps off and removed the drainpipe all the way to the sump. It isn't blocked. I tried drilling another breathing hole in the cap but that didn't help either.

Any ideas? :confused:
 
Your standpipe is possessed, I recommend calling an exorcist.

On a more serious note, my durso standpipe use to make a flushing noise, and it got resolved on it's own in time. How long has it been like this?
 
I think I found the problem. I have a flex line going from the tank to the pipe going into the sump. There was a pretty large S-bend in the line that I had repositioned while doing some cleaning. I moved it to make it almost level until it dropped into the sump and a huge air bubble gurgled into the sump and then I put it back into its former position. Now it's silent as it should be.
