After performing leak detection for property we found that this unit had 2 leaks on the drain system both being in the full bathroom. First leak being due to a broken drain inside the wall for the bathroom sink, and the other being due to a bad seal for the toilet. Opened drywall and replaced approximately 4’ of damaged/cracked cast iron drain for sink and installed new P trap assembly. Also pulled and replaced wax ring for toilet. After pulling toilet we noticed existing toilet flange was extremely low and about 2” below the floor when the flange should be level or on top of existing flooring. I believe the wax rings failed due to this and strongly recommend replacing existing toilet flange and raising to proper height to avoid future issues.
Ran water in all the units and found units 8 and 12 had active leaks to their drains. UNIT 8 While running water in unit 8 we found the when the toilet was flushed water began dripping into the carport leading us to believe the wax ring has failed, also when running the bathroom sink in the full bathroom water started dripping into the carport as well which indicates a break in the cast iron drain for the sink. In order to do repair we will need do open drywall in order to expose the drains UNIT 12 While running water in bathtub we found water began dripping into the car port leading us to believe that more then likely the waste and over flow and P trap needs to be replaced. Explained we will need to first open drywall behind shower to expose plumbing to identify exactly where the leak was coming from
