View Full Version : Venting a Condensate Pump

I'm using a condensate pump to catch some basement water seepage and pump it over to my sump pit. It's a strange application but seems to be working to an acceptable decree. My problem is.

The run to the pit is over 50 feet and the water is "stuck" in the plastic 3/8" condensate discharge line. Should I install some kind of "Vent" to allow the water in the line to properly drain? At this point I'm not sure I actually have a problem, when the pump turns on it pushes whatever water that's in the line out but something doesn't seem right with all that water sitting in the line.
Any suggestions?

Did you put slope on the line to the pit? Where's the water "stuck"? In the vertical raiser from the pump or in the discharge line to the pit? Back to you, Tom

Your condensate pump is working just fine as long as it pumps the water. No need to worry about the standing water in the clear hose line. You have no need to worry at all, just let it be. There is no need at all to vent a condensate pump. (it wouldn't serve any purpose). If you have no problems with the current set up, there is no need to change it. Please let me know what you think.

Most condensate pumps come with a check valve in them to keep the water in a vertical line from running back into the pump reservoir. So it is possible the check valve is causing an air lock and keeps the water in your line. And like mygirlsdad77 said it is not a problem.

What's done in sump pumps is a tiny hole, usually about 1/8" is drilled at the discharge at the pit. This intentionally causes the line to drain back into the pit and the loss is insignificant when pumping.

And I agree, so what if water is in the line.
