Hello all,
I bought my first house last year and have been doing my best reading up on all things homeowner related. I've been having an issue, which I believe I understand how to correct. But I want to arm myself with the correct knowledge before getting a plumber in to quote a fix.
The home is on a septic system with the waste leaving about 6 feet off the basement floor, so the laundry sink drains via a small ejector basin that sits on the floor directly underneath it. Ever since I've been here the sink in the master bathroom directly above gurgles anytime the ejector pump runs. Earlier I took the stopper out and determined that the ejector is actually generating enough positive pressure that it shoots the water in the trap about 2-3in high into the bowl of the sink.
In the attached photo the ejector pump has a dedicated 2in vent (green) that runs to the corner of the house and then up above the roofline next to the downspout and a 1.5in discharge (red) which is tied into the 1.5in master sink drain (blue).
So two assumptions I'm making based on some reading I've done on the forum already:
1. Since the ejector is flowing under pressure a vent is not needed in the line that it discharges into
2. Ejectors like this are supposed to discharge into a minimum 3in line (which is probably why its pushing the water out of the trap)
So my thinking for the fix is that the discharge could be moved to an upward facing wye fitting in the 3in line where the toilet ties in (see 2nd pic with possible wye locations marked).
Any insight would be greatly appreciated.
