Are There Maintenance Tips to Minimize Future Backflow Problems?

Simple, consistent maintenance can dramatically reduce nuisance leaks, failed tests, emergency shutoffs, and repair costs on your backflow preventer.

This includes routine visual checks, keeping clearances and drainage correct, protecting the assembly from heat and debris, exercising shutoff valves, and scheduling timely, certified annual testing. Los Angeles Backflow Testing Company recommends partnering with Atlas Backflow Services for a proactive plan that keeps you compliant and prevents costly surprises.

Why Maintenance Matters

• Prevents failures and fines: Small issues—like debris in checks or stuck shutoff valves—cause failed compliance tests and potential utility penalties.

• Protects public health: A well-maintained device reliably stops cross-connection hazards.

• Extends lifespan: Proactive care delays overhauls and replacement.

• Avoids downtime: Leaks and shutoffs disrupt tenants, businesses, and irrigation schedules.

Los Angeles Backflow Testing Company recommends treating your backflow assembly like any critical safety device: a little routine attention goes a long way.

Monthly Visual Checks Anyone Can Do

A two-minute look can save a service call.

• Scan for leaks or weeping: Check body joints, test cocks, and relief valve areas (for RPs). Continuous discharge often signals debris or a worn internal part.

• Confirm proper clearance: Keep 12–36 inches of space (per local specs) around the device for testing and repairs; remove weeds, trash, and mulch buildup.

• Keep vents clear: On RPs and vacuum breakers, never block or cap the relief/air inlet. Do not tape, bag, or paint over openings.

• Check drainage path: RPs must discharge freely to an approved air-gapped drain or to daylight; pooling water or submergence is a red flag.

• Look for damage or tampering: Bent handles, missing locks, or hit-by-vehicle damage (common near driveways) need quick attention.

If anything seems off, Los Angeles Backflow Testing Company recommends calling Atlas Backflow Services before the issue escalates.

Quarterly Owner Tasks to Prevent Future Problems

• Exercise shutoff valves: Slowly close and fully reopen both inlet and outlet valves to prevent seizing. Move gently to avoid water hammer.

• Clean around the assembly: Keep gravel beds tidy and ensure grade slopes away so water cannot pond around the device.

• Protect against sun and vandalism: In Los Angeles, UV exposure and tampering are common. Use ventilated, code-compliant enclosures or security cages; avoid airtight boxes that trap heat or block an RP’s relief discharge.

• Watch system behavior: Banging pipes, sudden pressure drops, or frequent RP discharge suggest debris, pressure spikes, or failing internals. Los Angeles Backflow Testing Company recommends a diagnostic test if you notice these signs.

Annual (and As-Needed) Professional Maintenance

• Certified testing: California and local purveyors (e.g., LADWP) require annual testing by a certified tester with calibrated gauges. Schedule early to allow for repairs and retesting.

• Internal service/overhaul: Rubber components and springs wear over time, especially in hard or sediment-laden water. Many assemblies benefit from a parts kit replacement every 3–5 years, or sooner if tests are marginal.

  
  

  Los Angeles Backflow Testing Company recommends preventive kit replacement when devices repeatedly “just pass” or after construction debris episodes.

• Post-work verification: Always test after plumbing modifications, fire system service, irrigation changes, or earthquake repairs. Disturbed piping can introduce debris and shift settings.

• Report submission: Your tester must file the official report with the water purveyor. Keep copies on-site for inspectors and insurance.

Atlas Backflow Services handles testing, repairs, calibrated reporting, and reminders so you never miss a deadline.

Environment, Installation, and Protection Tips

• Drainage is everything (RPs): Relief valves can discharge by design. Provide a proper air gap and drain capacity; never hard-pipe an RP relief directly to sewer without an air gap.

• Avoid submergence: Place devices above grade and out of flood-prone spots. Submerged backflow assemblies can fail and violate code.

• Heat, UV, and corrosion: Los Angeles sun bakes plastics and gaskets. Use UV-resistant enclosures with ventilation and avoid trapping heat. Choose corrosion-resistant hardware where irrigation overspray or coastal air is present.

• Bollards and barriers: If the assembly sits near drive lanes or parking, physical protection prevents costly impact damage.

  
  

  Los Angeles Backflow Testing Company recommends simple steel bollards for exposed installations.

• Clear labeling: Tag the device with its test due date and purveyor account info. Quick identification speeds service and inspections.

Water Quality and Pressure Management

• Strainers and flushing: Sediment is the enemy of tight-sealing checks. An upstream Y-strainer and periodic flushing reduce fouling. Clean strainers during routine service.

• Scale control: Hard water can scale checks and relief seats. Where scaling is chronic, Los Angeles Backflow Testing Company recommends more frequent inspections or scheduled parts kits.

• Tame water hammer: Slamming solenoids, quick-closing valves, or pump cycling can damage internals. Add water hammer arrestors and ensure slow-close valves where feasible.

• Pressure within range: Sustained high pressure accelerates wear. Verify pressure regulators are working, especially on irrigation and mixed-use services.

Special Notes for Common LA Systems

• Irrigation backflow (PVB/SVB/RP): Keep assemblies elevated per code, above downstream emitters. Fertilizer injection or reclaimed water exposure typically requires an RP—test yearly and after any fertigation changes.

• Fire sprinkler backflow (DC/DA/DCDA or RP/RPDA): Coordinate with your fire contractor. After any NFPA inspections or flow tests, confirm the backflow was not left partially closed or fouled by test debris.

  
  

  Los Angeles Backflow Testing Company recommends pairing annual fire and backflow testing to avoid missed paperwork.

• Commercial/industrial RPs: Restaurants, salons, labs, breweries, and process water users often see more debris and chemistry. Plan on proactive kits and tighter test schedules if failures recur.

Common Mistakes to Avoid

• Blocking vents or drains: Never cap, tape, or route RP relief discharges without an air gap and proper capacity.

• Painting over nameplates or vents: Keeps inspectors (and air inlets) unhappy. Light exterior paint is fine, but not over identification plates or openings.

• Leaving valves locked closed: After service, ensure both shutoffs are fully open; partial closures cause pressure issues and false failures.

• Skipping tests after work: Plumbing changes, meter swaps, or main breaks can introduce debris—test afterward.

• Paperwork lapses: Missing a submission deadline is an easy way to get fined. Los Angeles Backflow Testing Company recommends automated reminders and same-day electronic filing.

A Simple Maintenance Calendar

• Monthly: Visual check for leaks, clearances, vent obstructions, and drainage.

• Quarterly: Exercise shutoff valves; tidy enclosure and surrounding grade; note any hammer or pressure issues.

• Annually: Certified test, strainer cleaning, report submission, and a condition review for proactive parts kits.

• As needed: Test after plumbing changes, fire/irrigation service, main breaks, or seismic activity.

Compliance, Cost Control, and Peace of Mind

Backflow preventers are built to protect public health, but they perform best with light, regular care. By combining quick visual checks with professional annual testing—and by addressing environment, drainage, and pressure—you’ll limit emergency callouts, avoid fines, and extend device life. Los Angeles Backflow Testing Company recommends setting reminders now so you never miss testing windows or warranty opportunities.
