dishwasher drain
Posted by Mark on February 05, 19101 at 11:34:47:

When I moved in to my home, the dishwasher had a
3/8 od water supply line and a 1/2 inch copper
drain thru the floor down to the basement. It
didn't go to a disposal because the dishwasher is
not next to the sink. Now this 1/2 inch drain is
slow draining. The drain is too narrow for a
snake and must have a clog at or near either of
the two or three 90 degree bends. It goes thru
some finished areas of the basement, so I hate
to break into the drywall. Can the line be blown
out with air pressure? Or, should I bite the
bullet and install a 3/4 or larger pvc drain
instead. Thanks for your ideas.
