How to Connect a Dishwasher to a Double Sink
The procedure for hooking up a dishwasher to a double sink isn't any different than that for hooking one up to a standard sink. Dishwasher drain hoses connect to sink drains through a piece of pipe called the tailpiece. This is the straight piece of pipe located next to the curved p-trap. Tailpieces have nipples on the side that make hooking up dishwasher drain hoses a snap. Does this Spark an idea?
