Found leak in garage is coming from old cast-iron pipes and a couple holes in the lead toilet flange for the hall bathroom that was caused from being smashed by the subfloor which is leaking onto the floor in the garage every time the toilet is flushed. Need to replace Bathroom group cast-iron chunk that is in the garage ceiling. Total of three fixtures, which include one toilet, one tub, and one waste and vent connection for lavatory. Replaced the fill valve and flapper in hall bathroom due to deterioration of rubber seals. Replaced as a courtesy.
