Reduce assumptions before concrete is opened or a deep exterior excavation begins.

Asset records and accountable maintenance
Manage device locations, responsibilities, inspections, occupant instructions and capital decisions across one or more properties.
What to know
Record each valve’s location, model, protected drainage path, access, installation date, inspection history and responsible party.
Project context
Multi-unit drainage arrangements can affect code, rebate and installation suitability. Do not assume a single valve can protect every unit.

Owner handover
Work orders, tenant notices, emergency contacts and annual inspections should be coordinated rather than left as informal knowledge.
Project checklist
Use the assessment, authority requirements and written scope rather than choosing from a generic product package.
