hi. im desparately in need of suggestions. my washing machine drain overflows onto my basement floor. i have snaked the lines and they seem clear. the 4 problems i see are this: 1) the pipes are only 1 1/2". 2) they drain into the main which is about 4 feet off the ground. 3) the washer is elevated on a plywood platform. its about a foot high. 4)the main drain line is about 5" away on an adjacent wall. so the current pipe is horizontal for a good 4-5'. was planning on replacing the pipes with 2" pipes and removing the platform and just leaving the washer on the floor. will that be too much height for the drain to flow properly? also will the 2" make that much of a difference in being able to handle the outflow of wastewater? do i need to do something about that long flat run of pipe? should i raise the standpipe? i'm sorry if this is not clear, butexplaining this is a lotter harder then i thought. a pic would probably be much easier. any help would be appreciated. thanks!
