Sump Pump Air Bleed Hole
Hi People,
Need some helps on Sump Pump Air Bleed Hole.
I just installed Basement Watchdog Sump pump. I got below from the manual.
It said that "When a check valve is used, a 1/8 in. (3.2mm) air bleed hole must be drilled in the PVC pipe above the pump. Drill the hole at a 45° angle
toward the bottom of the sump to avoid splashing water outside the sump
pit."
So my question is which angle I should drill the hole; opt1 or opt2?
Thank you for helps.

Thank you Furd. That is what I thought. If I go Opt1, it will have water jet comes out from the hole when pumping water.
I like your idea to have 1/8" pipe. But how? Can you post a picture please?
Thanks.

No picture but it is easier than it sounds. Drill the hole with a 5/16 inch bit and tap it with an 1/8 inch pipe tap. Don't run the tap all the way in so as to have the fitting "jam up" sooner. Get a brass 90 degree tubing fitting; 1/8 inch on one side and 1/4 inch tubing on the other. Screw the fitting into the tapped hole and point the tubing connection down. Add some tubing and you're done.
I don't like an 1/8 inch vent as it is too easily plugged by debris. !/4 inch is not too large. As long as the vent hole is below the sump cover you don't really need the tubing going down.
