Why every sewer repair starts with a camera — and what each finding means.
If you searched "sewer camera inspection", you probably need a real answer in the next few minutes. Here it is — written by licensed plumbers who handle this every week in Ontario.
The short version. Most "sewer camera inspection" situations come down to one of three causes: a fixture-level problem you can confirm at home, a supply-side issue that needs a pressure test, or a downstream blockage that requires a camera. Knowing which bucket you're in saves time and money on the call.
What we'd check first. Start at the closest fixture and work outward. If the issue is isolated to one location, the fix is usually local — a worn cartridge, a clogged aerator, a failed shutoff valve. If multiple fixtures share the problem, the cause is upstream and needs a pro.
Why this matters in Ontario. Local water quality (hard, ~270 ppm in most of SoCal), older galvanized service lines, and clay sewer laterals mean a small symptom often points to a bigger underlying issue. We've seen this exact problem hundreds of times in Ontario homes.
When to call us. If you can't isolate it, if water is actively moving where it shouldn't, or if multiple fixtures are involved, stop and call. Call (951) 582-2433 for Sewer Repair & Repiping in Ontario, 24/7.
