Sewer Smoke Testing Jacksonville FL

Find the Source of Jacksonville’s Sewer Odors

Sewer gas odors inside a Jacksonville home are more than unpleasant — they can indicate structural failures in your drain system that allow methane and hydrogen sulfide to enter your living spaces. The challenge is that most sewer leaks are invisible until they cause a serious problem. Smoke testing makes the invisible visible.

At RiverCity Plumbing, we inject odorless, non-toxic theatrical smoke into your sewer system under slight pressure, then watch for where it exits. Every crack, unsealed connection, dry trap, or abandoned pipe stub that allows sewer gas to enter your home will be clearly revealed by the smoke — and documented on video. This gives you definitive evidence and a clear repair plan.

Why Jacksonville Sewer Systems Need Smoke Testing

15.3 GPG Hard Water Erosion

Jacksonville’s hard water corrodes cast iron vent stacks from the inside out, creating pinholes and cracks at pipe joints that allow sewer gas to escape into wall cavities. Hard water treatment slows this process.

Shifting Sandy Soil

The 904’s sandy soil shifts seasonally, shearing sewer pipes at foundation entry points. These hairline cracks are invisible on the surface but reveal themselves immediately under smoke pressure.

Historic “Ghost” Drains

Older homes in Avondale (32205) often have abandoned floor drains, laundry connections, and cleanouts that were closed but never properly sealed — all potential sewer gas entry points that smoke testing reveals.

Humidity & Air Pressure

Jacksonville’s high humidity and frequent pressure changes dry out P-trap water seals faster than in cooler climates. Dry traps in rarely-used fixtures allow sewer gas to enter freely — smoke testing identifies every dry trap location.

Sewer Smoke Testing Services

Non-Toxic Smoke Generation

Using odorless, non-staining theatrical fog injected into the sewer system under slight pressure. The smoke visualizes the entire drain network and reveals every breach within minutes.

Visual Leak Identification

Systematically monitoring all exterior vents, foundation penetrations, and interior fixtures to document exactly where smoke exits the sewer system. Every finding is photographed and video-documented.

Rodent Entry Detection

Smoke testing reveals every gap, crack, and opening large enough for rats and mice to enter your sewer system in Mandarin (32223). We mark every entry point for targeted exclusion.

Dry Trap Diagnosis

Identifying P-traps that have evaporated, allowing sewer gas to enter freely. We pre-fill all known traps before the test and then identify any we missed by watching for smoke entry points inside the home.

Cross-Connection Testing

Identifying improper connections between drain systems — such as a storm drain that is cross-connected to the sanitary sewer — which creates odor problems and regulatory compliance issues.

Written Assessment & Repair Plan

A detailed written report of all findings with photos and video, plus a prioritized repair plan with upfront pricing for each identified issue — giving you a complete picture before committing to any repair work.

Transparent Smoke Testing Pricing

Sewer smoke testing pricing is based on the size and complexity of the system being tested. We provide a fixed, upfront quote before testing begins. The cost of smoke testing is almost always far less than the cost of guessing and opening walls — it gives you a precise repair target before any demolition work begins.

Your Questions

Sewer Smoke Testing FAQ

Is sewer smoke testing safe for my family and pets?

Yes. We use non-toxic, theatrical-grade smoke that is odorless and leaves zero residue — the same material used in stage productions and theme parks. The smoke contains no chemicals, won’t stain surfaces, and disperses completely within minutes. We do recommend keeping children and pets away from the immediate work area during testing as a precaution.

What does it mean if smoke enters my house during the test?

Smoke entering the house confirms there is a breach in your sewer system connecting the drain lines to your living space. This is exactly what we are looking for. In older homes like those in San Marco (32207), this commonly indicates a cracked cleanout, an improperly sealed floor drain, or an abandoned pipe stub that was never capped. We document the entry point on video and provide repair options.

How long does a sewer smoke test take?

Most residential sewer smoke tests take 1–2 hours. Before the test, we fill all P-traps with water to seal floor drains and rarely-used fixtures. We then inject smoke into the sewer system from a cleanout and monitor the property for 20–30 minutes while the smoke pressurizes the lines. We document all findings with photos and video before providing our assessment.

Can sewer smoke testing find rodent entry points?

Yes. Sewer smoke testing is one of the best methods for finding where rats and mice are entering your sewer system in Mandarin (32223) and other suburban Jacksonville neighborhoods. Smoke will exit from any opening large enough for a rodent — including cracks at pipe joints, holes in vent stack screens, and broken cleanout covers. We mark every entry point we find for targeted exclusion work.
