Assess connections
Confirm which units and fixtures are served by each lateral and whether a valve would comply with the applicable code and building use.
Backwater valve specialists
Shared drains, multiple units and operating schedules require a more careful review than a typical single-family installation.
Properties with more complexity
Multi-unit, commercial and managed properties may need engineering, staged work and clearer responsibility for connected plumbing.
Confirm which units and fixtures are served by each lateral and whether a valve would comply with the applicable code and building use.
Plan fixture shutdowns, access, excavation, tenant communication and inspection timing before work begins.
Keep camera videos, permits, as-built information, access locations and maintenance history available to management and service teams.
Scope matters
Shared laterals, multiple dwelling units, commercial fixtures, interceptors, pumps and unusual drainage arrangements require a project-specific review. We do not represent a standard residential device as suitable without that assessment.

Share the property type, number of units, known drain layout and the reason for the assessment.
