Customer had a leak on their 1/2 copper 90 just past their recirculating pump. Cut out section and plumbing in new section with copper. Also noticed customers pump was set to run 24/7. Set customers pump on pre-set timer customer had already selected. Customer also had a lot of water damage on water heater stand and surrounding drywall in garage. Strongly recommend doing proper demo and remediation to dry down structure and prevent mold growth.
