'How often should I get my drains cleaned?' deserves a more honest answer than 'annually' — because for many homes the honest answer is 'when they need it,' while for others a schedule is the only thing standing between the basement and a backup. Here's how to know which home you live in.
Homes that don't need a schedule
Newer homes with PVC drains, no history of backups, no mature trees over the lateral, and sensible drain habits genuinely don't benefit from calendar-based cleaning — there's nothing to clean. For these homes the smart plan is behavioral (no grease, no wipes, strainers in drains) plus responsiveness: treat any slow drain or gurgle as an early warning worth a look, not a reason for a standing subscription. Beware anyone selling annual jetting to a five-year-old house with no symptoms.
Homes that absolutely do
Scheduled maintenance earns its keep where a known condition guarantees recurrence: root intrusion awaiting permanent repair (clearing every 6–12 months keeps flow while you plan); a documented belly collecting sediment (jetting on its demonstrated interval); old cast iron with heavy internal scale (periodic descaling extends its life); homes that have had two or more backups in recent memory (the third is a matter of time, not luck); and any home about to finish a basement above a line with history — clean, inspect, and fix before the drywall.
The commercial rule
Restaurants and food-service kitchens are their own category: grease production makes line jetting on a 3–12 month cycle (volume-dependent) standard practice, paired with grease-trap pumping on the 25% rule. Multi-family buildings benefit from scheduled main and stack cleaning because one resident's habits become every resident's backup. In both cases, after-hours scheduled maintenance costs a fraction of an operating-hours emergency.
The inspection alternative
For homes in between — older lines, no current symptoms — a periodic camera inspection beats blind cleaning: it tells you the pipe's actual condition, whether cleaning would accomplish anything, and how the clock is running on aging materials. Inspect on purchase, after any backup, before any basement renovation, and every few years for laterals past middle age. Cleaning treats; inspection informs.
