A: Oh Danny-boy, the pipes are calling. You must really like having parties at your basement bar to go through all this work! The good news is that since you are just draining a bar sink you are dealing with "gray" water, not sewer water from a toilet. A graywater discharge system is a lot easier to install than a sewer ejector pump, and the equipment is a lot less money. Cheers to that!

The system most commonly installed for sinks and laundry stations is called a laundry pump — basically a small (five gallons or so), self-contained, sealed chamber with a built-in pump. The housing also has connections for the incoming water, discharge line and vent line and the unit usually plugs into an approved electrical outlet. Water drains into the laundry pump tank, and when the tank is full, a float switch turns on the pump and discharges the water to the final gravity drain connection on the line. This allows you drain water "up and over" as you stated.

Please note that laundry pumps usually require local permits and must be installed to local building codes. For instance, check valves, GFCI electrical outlets, outside venting of the tank and drain distance restrictions are some of the issues that may need to be addressed. Bottom line is to check all your local codes before you start this job. A licensed plumber may be a good idea to bring in on this one, and maybe you can get a break on the price if you promise to invite them to your next party. Open bar, of course!
