Code requires that all the fixtures must be vented in the conventional manner and a sewage ejection pump assembly must have a separate dedicated vent through the roof, which may not be connected to any other vents in the structure.

From your description it would appear that your rough-in was initially installed during the build, in which case the fixture venting would have been inspected and i would assume that it is good to go.

Based upon your description the only thing you would need to do is install the fixtures and the sewage ejection pump assembly.

When installing the sewage ejection pump code requires that the receiver vessel MUST BE fitted with a removable air tight lid and a vent line from the vessel should be connected to the vent that is labeled for the sewage ejector.

On the vertical waste line from the ejector pit you are required to install a "backflow preventer" and slightly above that you are required to install a Manually operated gate valve, which could be closed to prevent back flow while servicing the backflow preventer or pump unit.

Thanks for the reply. I agree with you on that it was approved when inspected - so it should be ready to go.... so just for my curiosity, how are these vented - because I see no pipes coming out of the concrete and connecting to the vents anywhere.

One more question - I would like to put a wet bar in the basement - but I didn't plan for this so there is nothing roughed for it - however the spot where I plan on placing the sink is against the wall where the sewage ej is located on other side of wall. Is there a way to drain this sink into that pit? Maybe create another hole, and find a way to seal it? Thanks again.

In regards to my previous post - I found this diagram out on the web. So would I run a vent from my sink plumbing and meet up with the vent from the ejector, and then tap into the vent out the house?

And if anyone can address my second question from my previous post?

Thanks again for your repsonses.

reading further into the article mentioned above, and addressing my question about the wet bar drain.... should I just drain the wetbar into the pipe for the vent. So I guess If I ran a 45 T off of the vent pipe coming out of the ejector pit, and connected it to the wet bar drain - would that work?.... or maybe I'm way off base. Any opinions? Thanks.

You may not tie any vents or drains into the sewage ejector vent line. Sewage ejectors require a separate dedicated vent from the sewage ejector vessel through the roof and it may not under any circumstances be combined with any other vents or stacks in the structure.

The manor in which you may vent the wet bar sink is totally dependent upon which code you are under.

In order to determine which method would be easiest for you I would need to see a diagram of your layout.

If you can use your graphics program to create a simple layout showing the approximate distance from the bar sink to the drain going into the sewage ejector and either tell me which code you are under or tell me what city and state you are in, then email that to me, i will be glad to figure it out and return the solution.

OK. I made a sketch here - hopefully it works. Here it is:

The text is small - but you can see the 3 piece plumbing - going to the S.E., the vent for the ejector is center of pic., and the wet bar (which has not been roughed) is adjacent to the wall where the ejector is. I'm in Michigan. So that would be great if you can give some info on how to get this done. Thanks.

Your in luck, The Michigan Plumbing Code is based upon the 2006 International Plumbing Code (IPC), which is a lot more liberal on venting than is the UPC.

Given that your original fixture layout was done during the build and obviously inspected, we shall assume that the venting is okay in that area.

For your proposed bar sink you will by necessity have a vertical riser in the wall behind the sink which will run from the drain line up to the sink fixture arm.

From the base of that riser you can run a line to the 3" from the bathroom area and tie it into the 3" before it enters the sewage ejector vessel. The tie in to the 3" must be made by means of a Wye fitting. You could either get a 3x3x1-1/2" wye, which is a 3" wye with an 1-1/2" side inlet or you could use a common 3" wye and install a reducer bushing on the side inlet to accept the 1-1/2" drain line.

If the total length of the 1-1/2" line from the base of the riser to the inlet on the 3" is 6' or less you will not need any additional venting. (It will wet vent from the 3" main line.)

NOTE: The code prescribed trap and drain for your bar sink is 1-1/2" however code will allow us to increase a line by one nominal trade size, therefore if the length described above is greater than 6' you could increase the line to 2" and would be allowed 8'.

Out of curiosity, are you absolutely sure of the line layouts in your drawing or is that your best guess based upon the fixture layout? If it is a guess, i have prepared a drawing which is more likely the correct layout and i could post it for you.

you must discharge that sink into the line entering the sewage ejector vessel or into an aux input to the vessel.

Code prohibits making any taps into the vent line.

If you made a tap into the discharge line all the effluent being discharged from the pump would take the path of least resistance up you sink drain and you would have a geyser of effluent spewing from the sink drain and all over the room.

Yes I figured I couldn't tap into the discharge line for that very reason - which Is why I mentioned the vent. Aside from code reasons - what is another reason for not tapping into that vent? Would my sink be gurgling?

But you mention an Aux input into the pit - how can I do that? That is really what I am trying to figure out. Thanks again.

So I talked w/ the plumber who I contracted out to plumb my house - to get a bid on doing the work in the basement.... as I suspected more $$$ than I have right now - so either I wait, or try and do it myself.

But one thing he mentioned when talking to me - was that the sink in the rough plumbed bath would have to be tied into a vent. So I assume like I thought before that the S.E. would have a vent pipe / and the sink would meet up what with that run, and T off into the vent out the house?

and if someone has any input on the wet bar question from above again?
