In Reply to: wash-machine drain pipe running over posted by hawkins on January 20, 1998 at 19:16:31:
: Sometimes when my washing machine drains the drain pipe runs over. I put liqid plumber down it but it still runs over,sometimes. What should I do?
There are several possibilities. Most likely, the drain is partially clogged and needs to be cleaned mechanically, not with liquid plumber. Other
possibilities are that the drain line is too small (2 inch is preferred for a washing machine, but 1 1/2 " was often used). Or the height of the
stand pipe may be insufficient. Although it varies with local codes, the stand pipe must usually be about 30" tall (measured from the trap).
