What to schedule
Clear sump-pump pit debris helps keep the water protection system observable and reduces the chance that a small maintenance issue goes unnoticed.
The baseline interval is seasonal. Usage, pets, dust, water quality, weather and manufacturer instructions can require a different interval.
Stop before the task becomes repair work
Use qualified service for live electrical testing, gas work, refrigerant work, roof access, hidden leaks, structural damage or required disassembly.
