Customer contacted us due to no hot water in the home. Upon arrival, I was shown an existing Rheem 36-gallon lowboy electric water heater (3500 watts), manufactured in 2015. The unit was no longer producing hot water and had exceeded its typical life expectancy. After assessing the condition of the water heater, I recommended replacing the existing unit with a new, more efficient model. I provided an estimate for the full scope of work, including the necessary permit, which was approved by the customer. The old unit was removed and replaced with a new Rheem 38-gallon lowboy electric water heater (3500 watts). All plumbing and electrical connections were updated as needed to ensure proper and code-compliant installation. The installation has been completed and fully tested. There are no leaks or operational issues, and the system is functioning as intended. All work was performed to current code standards. The job site was cleaned and the customer was informed of basic operation.
