Drain in the shop when the line runs up-hill?

Aug 28, 2006 7 Replies

Wondering if I have any options to put a drain into my shop when the slope of the ground is uphill a couple of feet.



A sink would be about 80 feet away from the house where I could tap into a basement sink drain. This line would need to run uphill a foot or two in elevation before dropping into the basement sink drain line.



What are the options besides a 5 gallon bucket under the sink?

If the end is lower than the beginning, the in-between can go up hill as long as it does not go higher than the beginning elevation. The up hill travel would essentially work like a stretched out p-trap. That said however, draining will be much slower and may clog more often.

Dig a deeper trench. Fall 1/4" per foot so your trench will need to slope 20" from start to finish.

If its only a sink, not toilet waste, just build a french drain. (Deep hole filled with gravel.) Or, a pump.

There are various ejection pumps and sewage pumping systems available for what you want. If you are only talking about liquid waste from the sink, how about putting a small cheap sump pump into that 5 gallon pail?

Mine goes from the J trap through the wall to the ground outside the back of my shop. It's just water, with a little soap mixed in from washing my hands. May not be legal but does no harm.
