: I need a rough estimate on how much it would cost to put in plumbing facilities (i.e. sewage, water pipes, etc.) for a 2152 sq. ft. : house with a master bathroom, regular bathroom, washer and dryer room, two spouts on the outside of the house, and a kitchen which are the only : water accessable areas. House has an upstairs and a main level floor. Just a rough estimate.$2500.00 to $25000.00 to many variables to give you a real price.DISCLAIMERAll advice is given with-out seeing the job, and hence all advice MUST be taken as advice with limited knowledge on the exact situation. NO responsibility can or will be taken. And yes, I am a licensed plumber with my own business in Brisbane Australia
