Hi all,
I'm going to break ground on full bathroom fairly soon, and have some basic layout questions, that hopefully you can assist with.
Basically I need to know the best way to layout the PVC and where to put the AAV's (Code allows them in Kansas) to minimize any future issues based on my configuration below.. Note am going into a Sump pump well (which is in a cabinet, up and out to main sewer line. Your help is greatly appreciated!! I have attached a diagram of my bathroom.
Thanks,
Jason

Some of the plumbers have better design drawing skills than me so Ill start with the basics. No sump pump. You need a sewage ejector pit, they are different and also have a different pump.

Thanks ballengerb1, I did order the ejector pit and cover, don't know why I referred to that as sump pump. Also, am Venting the pit with a 2" run to attic to tap into the roof run. Guess Im just having difficulty with the pvc layout due to the lack of a long run and position of toilet. Thanks again.

I suggest Liberty Sewer Ejector system. Liberty supplies all you need set in collection bucket, all assembled. You just attach sewer pipe, vent, and plug it in. Done. Here is link on Liberty Sewer Ejectors:

I can't lay out the drain for you because I'm not sure about the venting, especially with an AAV. I'm sure Mark will be here before long.

But I have a question for you.

How are you going to open the shower door?

If I remember correctly, ejector pits require a dedicated line, not connected to another vent.

Thanks HK Stroud, no door on the shower, my wife wants a tiled open shower. She can mess with the curtains etc.
Note the shower actually extends to the north wall bordering the linen closet/Ejector cabinet - I see in the quick mockup picture I attached there is a gap.
Thanks again

JM,
The size & length of the sump vent is determined by the discharge capacity of the pump; in most cases an 1 1/2'' vent is more than adequate. Both the IRC and IPC allow up to 270 feet of 1 1/4'' pipe to vent a 20 GPM pump / pit. Sump vents can tie into an existing vent stack, stack vent, or individual fixture vent - your local building code official can help you determine if your existing Dwv system will support such a connection.
I have installed scores of sewage ejector systems and find it helpful to locate the toilet as close as possible to the sump tank / pit - this will reduce the amount of floor demolition, backfill, compaction, and patching. A single 1 1/2 '' pipe can vent the bathroom group - I like to install a wye with a 2" branch connection in the drain pipe between the toilet & shower trap; this branch will serve as a drain for the lavatory, and continue up past the sink trap as the group vent - we prefer to run all under ground piping a minimum of 2", it can be reduced to 1 1/2'' immediately above ground for easier routing around or through the wall framing, and, in some cases the group vent and sump vent can be combined before they continue on to their connection to the existing plumbing vent system.............
