Scope of Plumbing Services – Japan Osaka
This Invoice documents the comprehensive plumbing maintenance and repair services performed by our certified Plumber team at the Osaka Riverside Commercial Tower, located in the heart of Japan Osaka. The work was carried out over a period of five business days (June 2 through June 6, 2025) and included the following major tasks:
1. Complete replacement of the corroded copper water supply piping on floors 12 through 18, including all branch lines, shut-off valves, and pressure regulators. The Plumber team removed approximately 340 meters of deteriorated piping and installed new Type L copper tubing with PTFE-sealed fittings.
2. Emergency repair and full replacement of the main sewage drainage stack on the 22nd floor, which had developed a critical leak causing water damage to the ceiling of the 21st floor. Our senior Plumber identified the fracture point, isolated the affected section, and installed a new 200mm PVC drainage assembly with proper venting.
3. Annual inspection and descaling of all 48 commercial kitchen gas lines and hot water recirculation loops throughout the building. Each Plumber technician performed pressure testing, thermal imaging scans, and flow-rate verification in accordance with Japan Osaka municipal building codes.
4. Installation of two new high-efficiency commercial water heaters (400L capacity) in the mechanical room on the B2 level, including all associated gas connections, condensate drainage, and safety relief valve assemblies.
