Utility Sink and the Floor Drain
Hi:

Next to the Hot Water Tank and Furnace there is a drain in the floor in case of a leak or something...if I put a Utility Sink in that area (easy because all the pipes are there) can I use the existing floor drain as the sink drain?

If it matters, I live in the Denver metro area.

Thanks,

Mitch

It should work, but two things you need to check:

1. Where the drain goes. Some floor drains just run to daylight, not the regular drainage system. While you could still likely get away with a utility sink draining as a 'grey water' drain it's good to know where things are going.

2. You may be required by local code to have a floor drain. If so, you can plumb the drain so that it can drain the sink and the floor.

jaybee nailed it. one other thing, there should be a 1inch gap between the drain from sink and the floor drain
its called a air gap, its a code thing in case the floor drain back up,it wont back up into the sink drain

i wanted to add, use 1 5/8 x 4 inch long unistrut
1 peice...and 1 peice unistrut 7/8 x 4 inch long
fasten to floor. and ancher pipe to the "strut" using a "strut clamp" the same size as the OD of your pipe
the 2 diff size of strut will give you plenty of "fall" for the pipe to drain. put a 90 degree elbow on the end of pipe
and cut a round hole in the floor drain grate. to accept the 90...

Thanks everyone for the information.

Silly me, I did not notice the big black pipe coming down from the kitchen sink, we'll just tie into that, at least we know that goes to the sewer pipe. Smile
