Hi,

First of all, what an AWESOME website!!

I found the following Speedball1 thread while searching for info on hooking up basement bathrooms to elevated septic: https://www.askmehelpdesk.com/plumbing/basement-bathroom-plumbing-sketch-53385.html.

I have a similar situation to Brian's .pdf sketch, and am wondering if I can get my hands on Tom's sketch with the rough plumbing layout. This would help me determine how I can best configure my space (based on what's necessary & where I have the room to squeeze it all in).

Hope you get this, Tom.

Thanks, Jeff

I have printed out the original drawing,(See image, I don't have the drawing I made.) Your layout's the same thing? I need a sewer main to tap into. Show the location under the cement and the direction of flow and I'll lay it out for you. Regards, Tom

Thanks for the response Tom; I was hoping you had the marked up copy saved somewhere.

Like Brian, I have an elevated septic discharge in the same location. If you turn his bathroom 90 degrees clockwise, you have my proposed layout (I have to squeeze the shower end in between a furnace and exterior wall).

Per your comments on Brian's thread, I really don't care if the lav & toilet are swapped (you made a comment that might be easier/ less complicated).

I'm hoping to locate the ejector pump between the shower and the septic, as my laundry sump is located where Brian's proposed ejector is.

I'm still in the planning/feasibility stage, so this is great info to have available. By the way, I would normally say "Hello from Rockford" and curse you for hanging out in sunny Sarasota, but it looks like you guys are getting your fair share of the cold down there about now as well.

Stay warm (er than I am),
Jeff

Brain I need to know thje location 0of the main and the direction of flow. Mark the drawing up and attach it. Thanks, Tom

Jeff:

Tom is having a problem posting his drawing of the plumbing layout for right now so he asked me to pop over and throw up a drawing for you... ;)

There are two different ways to do this. One way is to individually vent (1st drawing) each fixture and the other way is to wet vent (2nd drawing) the fixtures. You need to call a local plumbing inspector to find out what code requirements prevail in your area... ok?

To begin, a sewage ejector system requires a dedicated 2" vent that connects to nothing but the sump pit and exits out the roof/building by itself. The 2" waste discharge line requires a check valve and it will connect into the main sewer drain via a wye fitting as indicated in the instructions for your pump. Be sure to read the instructions as most sewage ejector systems require that a 5/32" hole be drilled into the 2" discharge pipe just above the pump (but still in the pit) to prevent air lock of the system. I also recommend that you install a 2" full port shutoff valve just above the check valve in case you need to service the pump in the future... you will thank me later... I promise!

As you can see... the WET VENTED SYSTEM is easier... ;) As mentioned, however, it may not be allowed.

Common to both systems:

All pipes pitch at 1/4" per foot.
Vents pitch toward drain.
Use 2" long sweep elbows as you come out of the ground

Let us know if all this makes sense... ok?

Glad to discuss!

Mark and Tom... :)
