   I think you'll find the problem with that is the pump would be expected to handle a wide range of flows, depending on whether the sink was running or the toilet was flushed.  And if the pump didn't run fast enough, the toilet wouldn't flush.

   Thanks.  What I'm envisioning is a pump in a pit with enough vertical section of 4" waste line to act as a resevoir thus creating a "closed" system.

   Most crocks or pump chambers are sealed, so what is the purpose of trying to create another type of closed system? If I am understanding your decription correctly, you are wanting an inline pump with no resevior crock.  You then need to have some type of pressure switch in the line to tell the pump when to come on, and shut off. It can be done, but agian, why reinvent the wheel? Your next problem would be convincing your local code enforcment authority that your system is as safe and reliable as the systems they have already approved.

   Good luck.

   If you just get a good system, it is well sealed and is a proven design.  I understand what you are trying to do; however, most of the sewage pumps are submersible and designed for installation in a reservoir, with the level switches, etc.  Goulds has some nice ones; I'd look at their systems.  http://www.goulds.com

   Thanks, I'll look into them.  If the seal is good and everything else is ok, then I guess it's not a big deal to have a pool of sewage in the crock?!

   Check out E-one,Barnes pumps, Orenco Systems, most of these use a fiberglass basin that is outside the home, they have bolt down lids and produce no smell. There is no way to have a pump in line with no sort of resovoir, it would burn up in short order. I run a wastewater plant and use Barnes systems and Orenco systems with excellent results, they have been in service for 15 yrs, don't skimp here you get what you pay for.

   Thanks, proven systems are the way to go but you never know what's out there unless you ask.
