What our Clients think about us
Your satisfaction is our priority.
What Is a Backflow Preventer - and Why Does It Matter?
A backflow preventer (or backflow prevention assembly) is a specialized valve system installed to stop contaminated or non-potable water from flowing backwards into your clean water lines or the public water supply.
Common examples:
Irrigation systems: Sprinklers and landscape lines that can be exposed to fertilizers, soil, and standing water
Certain commercial fixtures or equipment: Where chemicals or non-potable water are present
Some fire lines or dedicated service lines
Backflow preventers:
Allow water to flow one way only—toward the system they protect
Shut or relieve when reverse flow or pressure issues occur
Help protect both your home and the community water system
If a backflow device is missing, damaged, or not working, there’s a risk that contaminants could move upstream into potable water.
Why Choose Active Plumbing
Backflow-aware plumbing: We understand how backflow assemblies fit into your overall system—not just the device itself.
Repair vs. replace honesty: If a safe repair is realistic, we’ll tell you. If the device is too far gone or outdated, we’ll recommend replacement.
Leak & freeze damage savvy: Experience with above-ground units in the desert sun, occasional cold snaps, and irrigation tie-ins.
Property protection: A failed or leaking backflow can waste water, damage landscaping, and cause pooling near foundations—we look at the big picture.
Coordination-friendly: We frequently work with landscapers, HOAs, property managers, and small businesses.
Licensed & insured: Nevada License #0047021, trusted for backflow preventer installation and repair in Las Vegas.
Immediate Actions (What to Do Now)
If your backflow preventer is actively leaking or spraying, turn off the shutoff valve upstream of the device if you know where it is.
If you received a failed backflow test or notice, keep that paperwork handy so we can see the failure type and device info.
Take photos of the backflow device, surrounding piping, and any visible damage or corrosion.
Avoid making DIY adjustments to relief ports or internal parts—this can make leaks worse or damage the assembly.
Call Active Plumbing at (702) 438-3357 and let us know whether you need backflow preventer repair, replacement, or a new installation for irrigation or domestic water protection.
Common Backflow Preventer Problems We See
Visible leaks from relief ports, unions, or fittings
Device frozen, cracked, or broken after a cold snap or impact
Failed test reports indicating internal failure or leakage
Corroded or aged assemblies that no longer seal correctly
Backflow preventers installed too low, poorly supported, or in the wrong orientation
Landscape or irrigation systems that never had proper backflow protection installed
If a backflow preventer is leaking, constantly dripping, or has failed a test, it needs prompt attention.
Call & Problem / Project Review
You call (702) 438-3357 and let us know if you have a leaking device, a failed test report, or a new system needing protection. We ask for photos or basic info and schedule an on-site visit.
On-Site Inspection & Device Evaluation
We inspect the existing backflow preventer, piping, supports, and surrounding area, and review any test report or notice. We determine whether the device is repairable or better off replaced.
Repair vs. Replacement Options & Pricing
We explain our findings—leak points, visible damage, age, and overall condition—and give clear, upfront pricing for repair (if appropriate) and/or full replacement with a new assembly and valves.
Professional Backflow Repair or Installation
With your approval, we proceed:
For repairs: shut down and relieve pressure, replace or rebuild internal components or seals as appropriate, and address leaking fittings or unions.
For replacements/new installs: shut off water, remove the old or install a new assembly with proper shutoff valves, unions, supports, and orientation as required.
System Restoration & Leak Check
We restore water, bleed air, and then check for leaks, proper valve operation, and correct flow direction. We verify the assembly is secure, properly supported, and accessible.
Documentation, Coordination & Next Steps
We provide notes on what was repaired or replaced and any recommendations for testing or follow-up. If needed, we coordinate with your landscaper, property manager, or testing company so the device can be inspected or certified as required.
What’s Included
On-site evaluation of your existing backflow preventer and connected piping
Diagnosis of leaks, failures, or code/installation concerns
Repair or replacement of the backflow assembly and related shutoff valves/fittings (as scoped)
Secure mounting and proper orientation of the device, with attention to clearances and access
System restart and leak testing at all connections we work on
Written notes and recommendations for ongoing maintenance, inspections, or future upgrades
Costs & Timelines (What to Expect)
Many backflow preventer repairs or replacements can be completed in a single visit, depending on device type and access.
You’ll receive upfront pricing once we’ve inspected the existing assembly, piping, and installation conditions—before we begin work.
Costs depend on device size and type, repair vs. full replacement, accessibility and piping configuration, and any needed valve or support upgrades.
We provide a line-item estimate that separates labor, materials, and optional upgrades (e.g., improved isolation valves, better support, or relocation for protection/access).
Insurance & Claims Help
Backflow preventers are often part of compliance and safety requirements:
We can document what was installed, repaired, or replaced, along with device model and size.
Our documentation can support backflow testing reports and help show that repairs or replacements were professionally completed.
If a leak from a failed device caused damage (landscaping, walls, etc.), our notes can help explain the plumbing cause for insurers or restoration companies.
(Actual compliance, testing, and insurance decisions always depend on local rules and your specific insurer/policy; this is not financial or legal advice.)
Risks of Waiting (Why Act Now)
Contamination risk: A failed or missing device increases the risk that non-potable water can enter clean lines.
Property damage: A leaking assembly can erode soil, damage landscaping, or affect nearby structures.
Water waste & higher bills: Even “small” continuous leaks can waste thousands of gallons over time.
Code & compliance issues: Ignoring failed devices or missing protection can lead to notices, shutoffs, or fines, depending on local requirements.
More expensive repairs later: Letting corrosion, cracking, or leaks progress usually means more piping and valves need replacement down the road.
Methods, Materials & Quality Standards
Correct device type and sizing: We recommend and install backflow assemblies appropriate for the application and pipe size.
Proper orientation and clearances: Devices are installed with correct orientation, height, and access for service and testing.
Quality valves and fittings: We use reliable shutoff valves, unions, and supports to ensure a serviceable installation.
Code-conscious work: Installations and repairs are done to local plumbing codes and accepted practices.
Thorough leak and operation checks: Every assembly we touch is pressurized and checked for proper function and tight connections.
Frequently Asked Questions
Can you repair my existing backflow preventer, or does it always need replacement?
It depends on the age, condition, and failure type. Some devices can be safely repaired; others are too corroded or damaged, and replacement is more reliable and cost-effective.
Do I really need a backflow preventer on my irrigation system?
In many areas, yes—it’s either required or strongly recommended to protect drinking water from fertilizers, soil, and standing water in irrigation piping.
My backflow is leaking from the relief port—can I just cap it?
No. Capping or blocking relief ports is unsafe and not code-compliant. The leak indicates a problem that needs proper diagnosis and repair or replacement.
Can you move my backflow preventer to a better location?
Often yes, within reason. We’ll look at your piping layout, elevation, and code requirements and explain what’s possible.
Do you work with HOAs and property managers?
Yes. We regularly help HOAs, landlords, and property managers with backflow repairs and installations across multiple properties.
