Protection (Includes Compliance)

Plumbing protection provides assurance that all plumbing related assets are covered for operational, running and property insurance requirements.

This ensures that all common area assets are inspected every 12 weeks. At the time of inspection customers will receive a comprehensive condition report on all common hydraulics.

The difference from the compliance package is that, following inspections, we will provide customers with a report identifying problems. We anticipate that these defect reports will reduce future asset breakdowns and increase life expectancy.
