draining dehudifier to 4" pvc in basement

famdog

I've got a DeLonghi dehumidifier set up in my basement with a clear flexible hose hooked up to the unit's pump. The pump will pump the water up 10 feet (as advertised). I'd like to go up about 7' to a 4" pvc drain pipe above it which is draining water from the kitchen sink above to a trap (also in the basement) then out to the septic tank. There is an existing clear flexible hose + barb already installed in a similar capacity on this drain pipe run from the air conditioner/furnace.

Q: I want to do the same thing with a plastic barb I bought at the local hardware store. One end is a barb (for the hose) the other end is a 1/2" threaded male. Can I drill a 7/16" hole near the top of the 4" pvc drain pipe and tap in this adapter using silicone caulk? This pipe is drainage only on holds no pressure.

thx.

You don't have a floor drain in the basement?

DUDE!

just had this same thing come up at work yesterday, I was told they have a fitting on a sewer pipe that has the nipple to accept condensate pump hose. Havent' seen this coupling but wasn't looking for it. You could do it your way not sure how stable it would be, as for no pressure, that's only untill the septic backs up. As for at work, took a different route outside.

That needs to be an indirect connection not a direct connection like your talking about. Not only will sewage back up into your dehumidifier if you ever have a clog down the line, you've also got a sewer gas issue since you dont have a trap.

I wouldn't do itl...for one the reasons stated: sewer vent, backup, and I'll toss another one...hackish.

What room is the de-humidifier in? Is there a sump pump close? There has to be a better option than this....
