Plumbing Maintenance Checklist

Intro

A plumbing maintenance checklist is a structured set of inspection and preventive service tasks designed to keep a building’s water supply and drainage systems operating safely, efficiently and without interruption. In hotels and commercial facilities, plumbing systems run continuously under pressure, making them especially vulnerable to leaks, clogs and hidden failures.

From water heaters and circulation pumps to guest room fixtures and floor drains, plumbing issues often develop slowly and go unnoticed until they result in flooding, water damage or service disruptions. Preventive maintenance (PM) allows technicians to identify small issues — think failing valves, slow drains or pressure irregularities — before they escalate into costly emergencies.

A plumbing preventive maintenance checklist helps maintenance teams:

• Prevent water damage and unplanned shutdowns
• Reduce emergency repairs and after-hours callouts
• Maintain consistent water pressure and temperature
• Extend the lifespan of plumbing assets
• Support code compliance and safety standards

Without a checklist, plumbing maintenance becomes a reactive part of facility management. With one, teams can proactively protect both the building and the guest experience.

Pro tip: Using preventive maintenance software like Coast makes it easy to schedule plumbing PMs, attach checklists to assets and track recurring leak or pressure issues before they cause damage.
