The symptoms, decoded
A drain system announces trouble before it fails. Watch for:
- One slow fixture — a local clog in that fixture's branch line
- Multiple slow fixtures — buildup migrating toward the main line
- Gurgling from a tub or floor drain when the washer or toilet runs — air being forced through a partial blockage
- Sewer odor from drains — organic buildup, or a dried-out or siphoned trap
- Water backing up in the lowest fixture in the house — the main line is struggling; act now
Why chemical drain cleaners make it worse
Caustic drain chemicals rarely clear the real blockage — they burn a channel through it, leave the buildup on the pipe walls, and attack older metal pipes and seals in the process. If a plunger and a drain-hair tool don't solve it, the honest next step is mechanical: snaking or hydro jetting, matched to what a camera shows.
What a professional visit looks like
All Systems Pros works from any accessible cleanout, and uses camera diagnostics to see what's actually blocking the line before choosing the method: mechanical snaking for everyday clogs, hydro jetting up to 4,000 PSI for hardened grease, scale, and roots. Most drain cleaning runs $89–$350 depending on access and severity — with the price approved before work starts, and practical prevention advice before we leave.
