Utility sink with in line pump for waste drain

michael_34 Member Posts: 303
It's not a heating question, but I want to put a utility sink in my office. The main drain is 20' away. Any ideas.

    Check your local plumbing code

    Assuming that you need to pump -- there will be requirements in there for trapping and venting the sink and the surge tank for the pump, and for sizing the lines from the pump.

    isn't really that far.

    Are you talking about a slab or basement where cutting concrete would be involved in draining by gravity?

    20' away at 1/4" per foot for pitch would be 5" of pitch necessary to get it done.

    Even if on a slab I bet that could be done by gravity, unless the drain goes thru the foundation wall rather than thru the floor. Then the pump would be required.

    20 feet away on the horizontial

    I won't be cutting into the slab. I was hoping to tie into the bathroom sink drain. The utility sink is about 20 feet from there. There is no basement and there is radiant tubing in slab. No cutting.

    The piping will be exposed into the room. This is the way the big boss wants it. : 0

    But the real questions we all want to ask are,

    what color will the privacy partitions be and will they be on both sides?

    At least admit it!


    P.S. Hartell pumps get the nod and Liberty are pretty well made as well. Do not skimp on the pump, get the best you can afford.
