I just put my sewer ejector into service today. It’s a Liberty Pro370 with a 40 gallon basin that fills about halfway before the pump kicks on. The pump empties the basin of between 15 and 20 gallons in less than 30 seconds… it sucks that thing dry in very short order, much faster than I would have thought.
Anyway, the discharge piping is 2″ and consists of a check valve followed by a ball valve, then on to the septic system. Everything is ABS except the ball valve, which is PVC and is the type I would usually associate with hot tub piping. My plumbing wholesaler sent it with the pump unit.
The ball valve has glue fitting to which I glued thread adapters, which I then mated to ABS thread adapters. Of course, those threads leak a tiny bit. I teflon taped them before assembly. I was told NOT to use the ABS/PVC specialty cement to glue this section together, because apparently it’s not rated for pressure applications.
To fix the leak, I can either:
1. rewrap those threads, or maybe UNwrap those threads
2. demo the first few pieces of ABS and replace with PVC, and then convert to ABS using a Fernco, after the valves.
3. ???
Small consolation… I have the entire rest of the building under DWV test at the moment and it all holds.

Use pipe dope, it will be fine unless the threads are damaged.
I've been liking Teflon Pipe Dope lately for threaded joints that may drip a bit. Had good luck with a couple of water supply lines.http://www.kingssupply.com/item36.htm
Dave if you're going to unscrew it to fix it, use tape & a teflon impregnated pipe dope like megalok or rectorseal T Plus 2
