I am currently finishing my basement. The basement bathroom will have a shower, toilet, and sink. I would like to tap into my washing machine supply lines which run nearly over top of the new bathroom. The only con I see against this is that the lines are 1/2" (the 3/4" supply terminates into the laundry supply right behind my furnace).
My questions are (1) can I do this. We follow the International Plumbers Code 2009 which I believe allows for 4 fixtures. Am I counting the fixtures correctly?
(2) should I do this? The 1/2" line is only about 8 feet. Will I notice a difference? (well I don't think I will but will my guests?)
