Customer contacted us for a suspected leak behind a toilet. Upon arrival, we performed a thorough evaluation of the plumbing system and fixture area. We determined the toilet flange had failed, allowing water to seep beneath the fixture and into the sub floor area and crawl space .We documented the condition and provided video evidence for the customer. We removed the affected toilet and rebuilt an additional restroom toilet while on site due to deterioration of the sub floor, the customer will need to have the subfloor repaired/rebuilt before we can properly reset and secure the toilet to prevent future issues. Toilet rebuilt was confirmed to be working as intended via dye test.
