    Long discharge drain line versus smaller diamter piple into full 2
    Apologies in advance for asking another variation of the same question on this forum...

    Installing a HE washer and want to position the washer in opposite corner of current washer. Current drain is, say 36 inches and 2 inch. It goes into the wall nicely, through the floor and tees within say 5 feet of opening.

    This is a thirty year old house and never a drain problem here.

    We are moving the HE washer 10 feet lateral (if we can) to allow my daughter to sleep. It's a difficult chore to install the desired 2 inch line next washer in planned location. I think my options are:

    • long reinforced DW drain house along the wall (which is not too stylistic)
    • Install a 1.5 inch drain in the wall, then once in crawl, open diameter to 2 inch, turn 90 degrees, travel 8 feet and tee into 2 inch drain under the floor. This is a bit of work, no sense doing it if it isn't going to work. What are your thoughts?


    Longer term, we may use the old 2 inch stack for a laundry tub.

    Ergonomics suggest a counter adjacent to washer / dryer stack, thus the tub is still a far reach (but a big catch basin)...

    I'm thinking that while option #1 will only work if you connect the hose back into the old washer stand pipe and install a washer hose check valve,(see image) at the tub outlet.
    If you go with #2 ( which has no mention of either a trap or a vent) you will have installed a direct connection between your home and the city sewer allowing sewer gas to enter your home. Good luck, Tom
