I have a basement drain that is for water condensation from my heat
pump air handler.
In the cold weather months there is a noise coming out of this drain
that sounds somehow like air pressure is causing the water in the
drain to go up and down.
The drain is connected to a sump which is pumped to the main sewer
line.
What can be causing this annoying noise problem in the drain??? Can it
be prevented??
Thanks,
Victor

It sounds like it is air pressure making the difference. Does it do it
more on windy days?

I am going to make a guess that the end of it is below the high water
level in the sump. Just cut the pipe down so it ends above that water
level. Make sure there are no drains connected to it however.
