Upon arrival Howard and I discussed the issue he was dealing with. He explained that one of the drain lines underneath the house was leaking very badly anytime water was run. After a thorough evaluation it was discovered that there were numerous leaks on the cast iron drain lines. After presenting Howard with options he chose to have the failing parts cut out and replaced. To preform this work I started by Cutting out and removing the cast iron drain lines to the existing abs drain line. Re-plumb the home with pvc drain lines from main stack failure; tie existing lines into the replaced pvc. after completion of installation test to ensure proper function and verify no leaks Cut out and remove cast iron drain lines at the point of failure. Re-plumb the removed cast iron section/fittings with pvc drain lines. after completion of installation test to ensure proper function and verify no leaks
