We had to cut several feet of pecks pipe out and drill some holes to reroute the lines that were hanging freely then being that they were exposed they insulated them and strap them to the bottom of the floor joist. On the waste piping we cut out a large section of 2 inch and 3 inch we had to change out some of the fittings because they are not code to be laid on their back and installed also the vent for the toilet was run out the back and that is not code approved either we started from scratch re-waste piping half of the house in the crawlspace.
