Hi, I currently have two bathrooms on a well setup that does not maintain water psi if more the one thing is calling for water (bathroom and washer for example). I have an irrigation system, the existing two bathrooms, a clothes washer going constantly and plan to add 3 more bathrooms. Two of the new bathrooms are three floors up from the basement.

My limited experience says to add a storage tank and some kind of boost system. Anybody have suggestions?

Are you sure it's the pumps fault? How old is tour house? What material are the water pipes? Do you have a galvanized pressure tank or a small bladder tank? And last, What in hell do you need five bathrooms in a single residence for? A bunch of teen age daughters? Going to take in boarders? Got the trots and don't want to stray too far away from a potty? (That last one was a attempt of humor on my part) Any how I'm interested in why you need so many bathrooms. Regards, n Tom
