I have a slab house and my polybutylene water main is broken under the house?
Typically when a line breaks under the house, we abandon the old pipe and determine the simplest path to get to the main shutoff valve. Typically that involves rerouting the pipe through a utility room or doing a short directional bore under the slab. Sometimes we can move the shutoff valve and regulator to a new location, which can save some rerouting work.
