If there is ever sewer back up there are no low spots for the back up to come out of.

there is always a low spot for sewage to come out of in the event of a backup. all you're doing with that pump is isolating it with a check valve. a back water valve on a gravity system will do the same thing, and is required by my code any time you have fixtures lower than the downstream manhole in the street. don't install a $500 pump and basin to save from buying a $20 fitting

Installing shower in basement


hmmm, I didn't plan on installing a pump. My floor drain drops 17" below the cement basement floor. The sanitary manhole out front has a depth of 8.85 feet. I'm not sure why ultimatetouch wants me to pump water up, only for it to fall further down???

Yeah, definitely be careful plumbing a basement. It can be tricky. Are you putting an apartment down there? I've been thinking about fixing up my basement for extra income.

In my code, a backwater valve is required anytime a fixture is located below the flood level (street level) of the upstream manhole. Thought for that is that if the city main backs up, it'll flood your basement before it overflows from the manhole. Only the fixtures in the basement should go thru the backwater valve. The alternative is an outdoor check valve that serves all fixtures (www.cleancheck.com) I'm not a fan of those, because your upstairs sewage can flood your basement, which won't happen if you isolate basement fixtures alone.

Again check with your local building codes. Where i liive you have to install an ejector when doing any bathroom work. Read carefully "the man". Yes if you have a drain (low spot) in the floor that doesnt go to the the ejector pit then you could get water from that area. Now days you are supposed run any new drains in the floor to the ejector pit.

Geez, i'm not trying to get in a pissing match with you dude. I know Illinios code (especially chicago) are all messed up with the unions making you do wierd things, but the OP isn't in Illinios. I got this from the Ohio Plumbing Code, which appears to be based on the UPC, like mine

SECTION 712 SUMPS AND EJECTORS
712.1 Building subdrains. Building subdrains that cannot be discharged to the sewer by gravity flow shall be discharged into a tightly covered and vented sump from which the liquid shall be lifted and discharged into the building gravity drainage system by automatic pumping equipment or other approved method. In other than existing structures, the sump shall not receive drainage from any piping within the building capable of being discharged by gravity to the building sewer.


heres the link if you'd like to check it yourself http://codes.ohio.gov/oac/4101%3A3-7 And yes, I see that it says existing structures, but if the OP's gonna do it right, obviously that's what his AHJ would want

Also found in OPC:715.1 Sewage backflow. If required by the “Ohio Environmental Protection Agency” or local sewer purveyor, a backwater valve shall be installed only for plumbing fixtures where the flood level rims of the lowest plumbing fixtures are below the elevation of the manhole cover of the next upstream manhole in the public sewer. Such fixtures shall be protected by a backwater valve installed in the building drain, branch of the building drain or horizontal branch serving such fixtures. Plumbing fixtures having flood level rims above the elevation of the manhole cover of the next upstream manhole in the public sewer shall not discharge through a backwater valve.
