Locating under slab plumbing
Posted by BAB on February 25, 2003 at 18:19:06:
I have a city map of my exterior sewer line from my house, but I need to figure out where the lines run within my house under the slab. I have a main stack for a couple of toilets, but also have a washing machine, shower and two sinks that enter the floor at different locations. I'm adding a second floor and will need to put in another stack to pick up a couple of new bathrooms. Trying to figure out where to tie in to the old system. I appreciate any help. Thanks!
