Protect people and document the pattern
Stop using fixtures that worsen a backup and stay away from contaminated water. Record affected fixtures, prior clearing work and when the issue returned. Do not enter a manhole or attempt utility infrastructure work.
Request useful inspection evidence
Ask whether the proposed inspection will locate the problem and provide footage or a written explanation you can review. Discuss the accessible cleanout and limits of inspection. Roots, damage and a blockage are possible findings to establish, not conclusions to assume from a recurring backup.
Define private-line and public-system responsibilities
Denver-area sewer service can involve different responsible entities. Identify the sewer provider from your bill and confirm the private/public boundary directly. A repair scope should address access, permits, excavation or trenchless suitability, restoration, testing and excluded work.
Before calling, distinguish one-fixture symptoms from a shared drainage problem and describe what you observed.
