The apartment located above the garage did not have existing washer/dryer water supply or drainage connections at the time of service. To accommodate the installation and proper operation of a washer/dryer combo unit, new water supply lines and a drain connection were installed. All plumbing was routed through the accessible garage chase to ensure proper support, accessibility, and long-term reliability. All work was completed in accordance with applicable local plumbing codes and industry standards. The installation provides safe, dependable, and code-compliant operation of the washer/dryer unit. The system was tested upon completion to verify proper function and to ensure there were no leaks or drainage issues.
