Basement Bathroom Plumbing - Rough in Backwater Valve
 
I am trying to figure out how in the world to frame my basement bathroom. There is a backwater valve that would end up right in the middle of the room. I know that code requires access to this valve and most basement rough ins have this valve much closer to the sump pump or other mechanical area, not in the middle of the bathroom.

Any ideas for how I would be able to finish this bathroom with the BWV in the middle of the room?

What am I missing or am I looking at this all wrong?

Thanks for any help or answers you can provide!

Ayuh,.... WHY is it in the middle of the room,....

Seems the answers are, move the valve, or move the room,....

Thanks for the quick reply! That is what I was afraid of. Are there any major concerns to jackhammer the floor to move the BWV 4-5 feet left of the current location? I assumed this valve is aligned to go straight out of house to city lines, so wasnt sure if injecting new bends or turns into the line creates any problems.

Here are a few pics/diagrams of the basement and where the pipes are located.

Ayuh,.... Yer drawin's don't say where the sanitary pipe exits the buildin',.....

The sump pump, is just a ground water trap, Right,..??

This toilet is goin' to drain into the sewer system, without a lift pump, Right,..??

I am not 100% sure where they exit. I am guessing it would either be on the right, near the floor drain or left of the sump pump.

Ayuh,..... Ya gotta figure out exactly What's there now, where it is, 'n where it goes,....

Otherwise, how ya gonna hook up a toilet, without knowin' where it's goin',..??

Mappin' out the existin' system, should lead ya to where the pipes are, 'n where they go,...
Ya might have to pop a cap here, 'n there to see which direction, or not,...
But ya gotta know where stuffs at, Before ya begin,.....

The plumbing rough in was all done when the house was built to code. If I dropped a toilet on there now, I think it is a safe assumption it would drain properly, but maybe I am missing something.

I guess I am trying to figure out if I can simply extend the existing plumbing over 5 feet in the current configuration. Maybe what you are telling me though is that it is not that simple... I was thinking that I would leave everything, as is... just move the BWV 5 feet over and tie back into the same connection it was previously tied to...?

Ayuh,.... I've never had to deal with a back up valve, but I believe it could be installed anywhere near the exit of the system,....

IF the pipe is goin' where ya want the valve, I don't see why it wouldn't work,....

I donno why they'd have put it in the middle of the floor in the 1st place though either,....

The UPC plumbing code wants the valve on the basement part of the system. This means it may not be possible to move it.
You need to determine where the line is that serves the main floor. Look for an exterior clean out. This will tell you where the drain enters.

The rule I mentioned above may or may not apply per IPC. Do you know which code you use?

Ghostmaker 01-13-2016 08:34 PM

Some for IPC the backwater valve is only for basement stuff nothing above that level can pass through it if it was installed correctly and that is a big IF.

A few questions to answer

Are you on public sewer?

If so which side is the front of the house?

Are you on public water

Where does it enter the house?

Start looking in the water area for your main sewer cleanout.

Ghostmaker 01-13-2016 08:40 PM

Looks like your toilet should be facing the back water valve when installed the lav to its right. You only need 24 inches in front of the toilet to the wall. It should work...

A round toilet is 16 inches from center of the hole to the front.

Front of the house is the bottom center of the drawing above.

The main water line enters the house about 8 feet to the right of the sump pump through the wall on the bottom of the diagram.
