FAQs
What are the most common reasons a commercial backflow preventer starts leaking?
In Johnson City, the main culprits are worn or fouled internal seals, mineral-scale buildup from our moderately hard water, freeze damage during winter cold snaps, and excessive downstream pressure caused by booster pumps or pressure-reducing valves that are set too low. Routine annual testing required by the City of Johnson City Water & Sewer Services usually catches early wear, but if maintenance is skipped these issues can develop into noticeable leaks.
Is it safe for my business to keep operating if the backflow preventer is dripping?
No. Even a small drip indicates that the check valves or relief valve are no longer sealing properly, which means there is a real risk of contaminated water reversing into the public supply. Johnson City follows Tennessee Department of Environment & Conservation (TDEC) cross-connection rules, and they consider a leaking preventer a potential health hazard. The device should be repaired or isolated immediately, and most insurance carriers require prompt action to remain in compliance.
How fast can your Johnson City commercial plumbing team respond and how long will the repair take?
We provide 24/7 emergency dispatch within Washington, Carter, and Sullivan counties and can typically be onsite in Johnson City within 90 minutes. Most leak repairs—such as replacing O-rings, check seats, or a relief-valve kit—are completed in 1–2 hours. If the assembly is corroded beyond repair and must be replaced, expect 3–4 hours including shut-down, installation, and post-repair testing.
Will my building’s water need to be shut off, and how will that affect business operations?
Yes, the backflow assembly must be isolated to service it safely. For multi-tenant or critical-use facilities (restaurants, healthcare, manufacturing), we coordinate with on-site management to schedule work during low-demand periods or after hours. Our plumbers set up temporary bypass lines when possible to keep fire-sprinkler and essential domestic water service running while the preventer is repaired.
Do I need permits or an inspection after the repair or replacement?
For simple rebuilds performed on an existing device, Johnson City does not require a plumbing permit, but the assembly must pass a certified backflow performance test afterward. When the entire preventer is replaced or relocated, a plumbing permit and subsequent inspection by the City’s Building Department are mandatory. We handle all paperwork, testing, and filing of the test report with the Utilities Cross-Connection Control Office on your behalf.
How can my facility avoid future leaks and extend the life of our backflow preventer?
1) Schedule the annually mandated test—many leaks are prevented by catching worn parts early. 2) Install a freeze blanket or heat tape on outdoor or unconditioned-space assemblies. 3) Have pressure-reducing valves serviced so downstream pressure stays within the device’s rated range. 4) Flush the line quarterly to remove sediment. 5) Keep a maintenance log; our technicians provide a digital copy after every service call so you know when the next kit replacement or inspection is due.
