Inventory every system
Record the unit location, drain route, termination, pump, safety switch, and service history.

Record the unit location, drain route, termination, pump, safety switch, and service history.
Attic units, finished ceilings, long runs, and repeat clogs deserve more frequent attention.
Give technicians and maintenance teams the same inspection and proof-of-flow checklist.

For a multi-unit property, the costly part of a clog is often not the pipe cleaning. It is the ceiling repair, tenant disruption, emergency dispatch, and uncertainty about which other systems have the same risk.
A useful asset record identifies each drain termination and links it to the correct air handler. Log standing water, float-switch trips, cleaning results, pipe repairs, and repeat failures.

A completed task should confirm that water travels through the full route without leaks and that every cap, trap, pump, and safety switch is restored. "Vacuumed the outlet" is not enough documentation.
Property operators and A/C contractors can also evaluate scheduled suction as part of a preventative program. Visit the Unclog Pro page to discuss compatibility, demonstrations, and multi-system planning.
