What is the Exact Process for Backflow Preventer Repair with Cover Your Brass?
1.
Pre-Inspection & System Evaluation
Our certified water treatment operators conduct a structured site inspection to assess pipeline layout, connection points, and system volume. We identify proper injection locations and verify that valves and discharge points function correctly. This evaluation ensures the potable plumbing system is physically prepared for chlorination disinfection and reduces the risk of pressure failure or chemical leakage.
4.
System Flushing & Dechlorination
After the contact period, we perform a high-velocity flush to clear the concentrated chemicals. Our approved de-chlorination agents neutralize residual chlorine before discharge. This step protects the public water supply, ensures compliance with environmental regulations, and restores the system for potable use.
7.
Final Documentation & Authority Approval
We issue an official Chlorination Certificate and compile all lab results into a formal report. Our team handles the direct filing of these compliance documents with your local water authority, ensuring a smooth sign-off so you can move forward with your project’s final inspection and legal water service activation.
2.
Controlled Chlorine Injection into Waterline
Using precision metering equipment, our team introduces a regulated chlorine solution into the pipeline. The dosage is calculated to eliminate pathogenic organisms without damaging internal pipe materials or fittings. Continuous monitoring of chlorine residuals ensures the entire water system reaches the required parts-per-million concentration for compliant chlorination disinfection.
5.
Bacteriological Water Sampling
Once the system is free of chlorine, we collect professional water samples. Our certified water treatment technicians use strict aseptic techniques to prevent any outside contamination from affecting the results. Pulling these samples correctly is the only way to ensure the laboratory data accurately reflects the actual cleanliness of your pipes.
3.
Required Contact Time Per AWWA Standards
The chlorinated solution remains inside the pipeline for the required holding period, often up to 24 hours, depending on concentration. This contact time allows chlorine to penetrate biofilm layers and eliminate pathogenic organisms, including bacteria and viruses. Maintaining proper holding time is necessary to achieve compliant water disinfection.
6.
Lab Testing & Compliance Verification
We then certify the samples for total coliform and microbial indicators to ensure the system meets potable water standards. The laboratory report confirms whether the system meets the required drinking water quality standards. This verification provides the formal report required for regulatory compliance and occupancy approval.
What Are the Signs Your Waterline Needs Disinfection?
The signs your waterline needs disinfection include failed water quality testing, cloudy or discolored water, foul odors from taps, a bacterial contamination notice, prolonged system stagnation, and recent plumbing modifications. These conditions indicate that pathogenic organisms may be present within potable plumbing systems. Chlorination disinfection restores water quality, eliminates bacterial and viral contamination, and ensures the water supply meets required drinking water standards.
