Hi all... first time poster. Every time I did a search on Google an answer from here came up so I thought I should just post my question directly.

I have a half basement in Atlanta, GA. I want to put a wet bar in it but it is completely finished and there is no plumbing in the area. I have read and figured out I can use an ejector pump to pump the drain to the closest place I can hook into the regular drains (in my laundry room).

What I want to do I run the drain pipe through the wall into my garage where the pump will be then run the piping along the wall and then through further down to the laundry room. The total vertical length that would be needed is about 6ft.

I have found most of the information I need but these are my twoquestions..

1) Do I put a P-trap between the sink and the ejector pump? The kind of pump I want to get is the one that sits in the 5 gallon drum that is above ground like the Little Giant WRSC-6 water removal system.

2) I don't know what type of venting needs to happen for this setup up. I know the pump has a vent hole on the top and am wondering if this is the vent I need to use and does it need to run to the roof or can I use one of the auto venting deals. Remember the pump will be in the open in my garage, not under a cabinet or something like that. Or is the vent in the pump something separate and I need to vent the drainage pipe before or after the pump?

Hope this all makes sense... looking forward to your responses!

Thanks!

How much water do you intend to run through the sink at your wet bar. The reason I am asking is that you can get a condensate pump or something similar that will dispose of a pretty good amount of water. So if it is just for melting ice and rinsing glasses and such that might be the thing for you. This would not require a vent or a trap and would have only one small discharge line that you would need to conceal.
I am telling you this just to give you something to think about. Like they say "Think outside the box"

You will still need a P trap below the sink to prevent sewer gas from backing up. The vent on the motor is not the vent stack in a plumbing system, it is something else. If your pump discharges into an existing drain pipe you might not need to add additional venting. Try to tap into the drain where other plumbing already is attached.

A condensate pump? I will look it up. The sink will be used for rinsing glasses, melting ice and it will also act as the drain for my kegerator. Nothing else will be put in the sink.

Condensate pumps are usually found in the furnace isle. 90+ firnaces and AC need to drain and these pumps allow you to drain up and over in the basement.

Go with your first inclination with the pump in the garage. There must be a trap to stop sewer gas from coming back into the home and the vent hole is for the 5 gallon container to breathe. A studor vent will airlock and the drain will appear clogged. The container may have an odor, this is why it will be best to vent outside. Do not connect it to another drain or the vent may back up. When installing the drain line don't forget the valve and the check valve as the directions say.

OK... so you are saying to vent the 5 gallon container outside to prevent any odor issues and as long as the drain I am attaching to is vented I am good with the drain pipe coming from the container? Just want to make sure I am clear on everything before I begin!

Thanks for all the help!

Yes... and according to the code, the drain from the container must be connected at least 10 feet downstream of a toilet.
