putting in two sets of washer dryers on the opposite sides of one wall (2x4).
I have an existing 2" drain coming out of concrete floor, everything else is planned
i plan to put a clean out near floor followed by a sanitary cross branching out with a 2" vent to basement ceiling vented to side of house.
My questions:
(1)
Will the 2" drain line be capable of draining 2 washers? The books i've seen list the fixture unit FU of a washer at 2, with a total of 4 for the 2 washers. The listed max FU of a verticle 2" pipe is listed as 10 and the max FU of a horizontal 2" pipe is 6. The 2" pipe coming out of floor changes to a 3" by a 3/2 bushing below the slab before it goes horizontal, so there is never a horizontal 2" segment of pipe carrying double capacity. The 3" pipe was not carried up the wall because it is 2x4.
[QUESTIONS 2&3 might need to be asked in another forum]
(2)
Being a 2x4 wall, a 4" dryer vent will not fit. I plan on running 3" dryer vent to ceiling and transitioning to 4", for each dryer seperately. Is this unsafe to have an approximately 6 ft. section of 3" vent pipe for each dryer or merely not ideal. Worst case I could use 2x2 lumber to widen the wall to allow 4" dryer vent.
(3)
I have to have the washer/dryer on the right stacked. How is this laid out? Dryer is ontop of washer right? Not sure of height requirements.
Please correct me, typically 120V washer outlet is higher than washer box in case of leaks. And the dryer vent and 240v would be higher than the washer box in a stacked setup.
