Venting Tips for Dehumidifier Condensate Pump Output
I've recently installed a condensate pump adjacent to a dehumidifier that is in a room separate from any drains, sinks, or convenient outputs. I was not emptying the DEHUM frequently enough, and didn't want to, and this has been a great solution.
It works great - about 3/4"D PVC - pumps up, then by gravity via slow decline it drains about 15' away into a utility sink. No issues/maintenance after about 1.5 seasons.
Only thing - I did not install a vent and it seems water gets trapped, sucked-back, etc - not efficient for the pump or good for standing water, and it just annoys me.
I do have a check-valve installed.
How do I install a vent - and prevent pressurized water from blasting out? I was going to install a "Y" 45-degrees back...but not sure how to terminate/etc. Looking for suggestions - thanks!

Condensate pumps don't need to be vented. Some water drains back but shouldn't be a problem. If you have a check valve in the line..... that could restrict pumping action and it should stop any water from flowing back.
