Backflow Preventer Testing and Certification for New Jersey Irrigation Companies The Sub-Contractor Partner That Keeps Your Schedule Clean and Your Clients Compliant
We are a certified backflow testing specialist — not an irrigation contractor. We do not install heads, run pipe, program controllers, or perform any irrigation work. Every irrigation service call and installation referral that comes our way goes directly back to you.

Why Sub-Contract Backflow Testing
The Sub-Contractor Partner That Keeps Your Schedule Clean and Your Clients Compliant
Your irrigation clients installed their in-ground systems because they trust you. They call you in the spring for startup, in the fall for winterization, and whenever a zone goes down or a head gets clipped by a lawn mower. That ongoing relationship — built visit by visit, season by season — is the most valuable asset in your business.
Buried inside that relationship is a compliance obligation most of your clients barely know about: the annual backflow preventer test. Every in-ground irrigation system connected to a public water supply in New Jersey must have a certified backflow preventer tested every twelve months under N.J.A.C. 7:14B, the state’s cross-connection control regulation. The test must be performed by an NJDEP-certified tester, and the signed report must be filed directly with the client’s water authority — whether that’s NJ American Water, Veolia Water NJ, a local municipal water department, or one of more than 200 other water authorities across the state.
That annual test is not your core business. It requires separate NJDEP tester certification, separate test equipment, a constantly updated water authority filing database, and the time of a skilled technician who could be installing a new system instead. South Jersey Backflow solves that problem — we serve all 21 New Jersey counties, sub-contract for NJ irrigation companies, bill you directly at discounted trade rates on flexible Net-30 and Net-60 terms, and refer every irrigation service call back to you.
The Hidden Overhead
What Annual Backflow Testing Actually Costs an Irrigation Company to Handle In-House
Most irrigation contractors who handle their own annual backflow testing have never fully priced out what it costs them. The individual test seems simple enough. The aggregate overhead is another story:
🎓 NJDEP Tester Certification
Every employee you put on backflow testing needs to pass NJDEP's written and practical exam and maintain it through recertification — training time and exam fees for what is a compliance service, not a profit center.
🧰 Test Equipment & Calibration
A professional test kit runs several hundred to over a thousand dollars per technician, and must be calibrated periodically — an out-of-calibration kit means a report the water authority can reject.
🗂️ Water Authority Filing Complexity
New Jersey has more than 200 distinct water authorities — each with its own required report format, submission method (email, online portal, fax), deadline schedule, and contact information. NJ American Water alone has multiple regional systems with separate filing contacts. Veolia Water NJ, the Passaic Valley Water Commission, Trenton Water Works, the Jersey City MUA, and hundreds of municipal water departments all have different requirements. Keeping that database current and accurate is a near-impossible task for an irrigation office whose primary expertise is in the ground, not in municipal utility administration.
📅 Seasonal timing conflicts
The spring startup season — when the majority of your annual backflow tests are logically due, since devices need testing after winterization — is exactly when your crews are busiest getting systems running, checking heads, and adjusting coverage. Pulling a technician off startup work to spend a morning driving between residential properties testing PVBs is a direct revenue cost during your highest-demand weeks.
📨 Compliance letter management
When a client gets a notice from NJ American Water or their local water authority about a missed annual test, they call you. Your office triages it, schedules a response visit, manages the urgency conversation, and tracks the resolution. That's overhead on every missed test in your client base.
Every one of those costs drops to zero when you sub annual backflow testing to South Jersey Backflow. Your crews stay focused on installation and seasonal service. Your office stays out of water authority compliance administration. And your clients stay compliant — with their irrigation contractor getting the credit for keeping everything in order.

What South Jersey Backflow Does for Your Irrigation Clients — On Your Behalf
📋 Annual Backflow Preventer Testing and Certification
South Jersey Backflow's NJDEP-certified technicians test all backflow preventer device types found on New Jersey irrigation systems — primarily pressure vacuum breakers (PVB) and reduced pressure zone (RPZ) assemblies for systems with chemical injection (fertigation). We test to current ASSE performance standards and generate a written certification report submitted same-day to the applicable New Jersey water authority. Your client receives written confirmation that their system is compliant. Their water authority gets the report. You get the credit for having a compliance program that works. See irrigation backflow requirements in NJ for a full explanation of what NJ law requires for irrigation cross-connections.
🔧 On-Site Device Repair and Rebuild
When a pressure vacuum breaker or RPZ assembly fails its annual test, South Jersey Backflow performs on-site repair and rebuild using manufacturer-approved replacement internals carried on every service vehicle — Watts, Febco, Wilkins, Ames, Apollo, and all other major brands. Most repairs are completed in the same visit as the annual test, avoiding a return trip and additional scheduling coordination. When a device needs full replacement rather than repair, we note it in our report and send the referral back to you. Device replacement means a new backflow preventer needs to be installed — that is irrigation contractor work, and it goes back to you with all the relevant details: address, device location, device type and size, urgency level, and client contact information.
🛡️ Backflow Preventer Enclosure Installation
Outdoor backflow preventers — which describes virtually every irrigation system backflow device in New Jersey — are exposed to freeze damage every winter. A PVB or RPZ that freezes and cracks in February means a flooded meter pit, a water loss, and a client calling you about a problem that started with a backflow device that wasn't protected. South Jersey Backflow installs insulated freeze-protection enclosures for outdoor irrigation backflow preventers throughout New Jersey. When a client's enclosure needs to be relocated, the backflow preventer needs to be repositioned to accommodate a new system layout, or the plumbing connecting the backflow preventer to the irrigation mainline needs to be replaced — that work involves plumbing and potentially irrigation system connections that are beyond our scope. Those referrals go back to you.
📤 Same-Day Water Authority Report Filing
The most common failure point in DIY backflow testing is the filing step — testing the device but never submitting the report to the water authority, or submitting it to the wrong authority, or submitting it in the wrong format. South Jersey Backflow files every test report with the applicable water authority the same day we test. We maintain current filing protocols for all New Jersey water authorities: NJ American Water (Raritan, Coastal North, Passaic, North, and Washington systems), Veolia Water NJ, the Passaic Valley Water Commission, Trenton Water Works, the Jersey City MUA, the Cape May County MUA, the Atlantic City MUA, and more than 200 individual municipal water departments and utility authorities throughout all 21 New Jersey counties. Your clients' test reports get filed correctly, on time, every time.
⚠️ Compliance Letter Resolution
When an irrigation client calls because they've received a compliance letter from NJ American Water or their local water authority, your company calls us. We triage the situation, schedule a priority service visit, complete the test and any necessary repair, and file the report — typically resolving the compliance notice within 3 to 5 business days. Your client goes from "panicked about a water shutoff threat" to "compliant and relieved," and your company is the irrigation contractor that made it happen.
Clean, Discreet, Structured Around Your Business
How the Sub-Contractor Relationship Works — Clean, Discreet, and Structured Around Your Business
You Stay the Client's Irrigation Contractor
When South Jersey Backflow arrives at one of your clients’ properties, we present as part of your service team — there for the annual backflow inspection on behalf of your company. We do not distribute South Jersey Backflow marketing materials to your clients. We do not discuss our rates with homeowners or landscape managers. We do not pitch additional services or attempt to establish a direct relationship with your client.
Your client relationship is yours. We are the specialist your company sends. That framing is completely natural — your clients know they have a backflow preventer on their irrigation system, they know it gets tested annually, and a technician arriving for that inspection is entirely routine. When we leave, your client’s confidence in your company is reinforced, not undermined.
Discreet Trade-Rate Billing — Always to Your Company, Never to Your Client
South Jersey Backflow invoices your irrigation company directly at discounted trade rates. Your client receives their bill from you, structured however you choose — incorporated into a seasonal service package, billed as a line item on your spring startup invoice, or handled however your pricing model works. We stay completely out of the pricing conversation with your clients.
Our invoices are itemized by property address and service performed, formatted to work cleanly with standard irrigation contractor billing workflows. What you charge your client for backflow compliance is your business — we bill you our trade rate, you apply your margin, and your client sees a bill from their irrigation contractor.
📋Trade Billing Terms for NJ Irrigation Sub-Contractor Partners
- Net-30: Payment due 30 days from invoice date — available to all irrigation sub-contractor accounts from day one.
- Net-60: Payment due 60 days from invoice date — available for established accounts after 90 days, or upon request for high-volume partners.
- No credit application: No personal guarantee, no formal credit check, no fee to establish terms.
- Trade rates: Discounted below our standard retail pricing — reflecting the volume and scheduling efficiency of a stable sub-contractor relationship.
- Invoicing: Discounted below our standard retail pricing — reflecting the volume and scheduling efficiency of a stable sub-contractor relationship.
Fully Insured and Bonded — Your Business Is Never at Risk
South Jersey Backflow carries its own general liability insurance and is bonded. When our technician is on-site at one of your clients’ properties performing a backflow test or repair, we are covered by our own policy — not yours. If something goes wrong during our service visit, our insurance responds. Your company’s coverage and your contractor’s license are not exposed by work we perform.
We provide a certificate of insurance and bonding documentation before beginning any sub-contractor relationship. This is standard procedure for every irrigation company we work with — we make it easy: request the certificate, confirm the coverage limits work for your business, and we’re set. All South Jersey Backflow technicians hold current, active NJDEP backflow preventer tester certifications, and we provide copies of those credentials on request as well.
The combination of our own insurance, current NJDEP certifications, and the technical competence that comes from 20+ years of backflow-specific practice means that the backflow work we do for your clients does not represent a professional risk for your irrigation company. We take that responsibility seriously, because the sub-contractor relationships we’ve built over two decades with New Jersey trade professionals are the foundation of our business.
Free Field Intelligence
The Annual Touchpoint That Keeps Your Clients' Irrigation Work Coming Back to You
The Annual Touchpoint That Keeps Your Clients' Irrigation Work Coming Back to You
Every annual backflow test is an on-site visit to your client’s property. Standing at the meter pit, our technician can see the mainline shutoff, the age of the device, the condition of the enclosure, and often the overall system. What they observe — and report back to you — is free field intelligence on your client’s system. An irrigation company with 300 annual test clients gets 300 annual on-site visits generating service referrals they’d otherwise have to create proactively.
1
We Spot It
Our technician notes a device needing replacement, a cracked enclosure, or an issue with the system connection.
2
We Report It
We include the observation in our service report to your company.
3
We Point to You
We tell the client that their irrigation contractor will follow up about the item — we do not quote the work or attempt to address it ourselves.
4
You Do the Work
You contact the client with the referral. You schedule the service. You do the work. You bill the client.
The irrigation contractor who sub-contracts their annual backflow testing doesn’t just offload a compliance burden — they create a systematic annual touchpoint at every client’s property that generates service referrals back to their own company. An irrigation company with 300 annual backflow test clients has 300 annual on-site visits generating field intelligence and service opportunities they would otherwise have had to create proactively.
What We Test
Irrigation-Specific Backflow Compliance in New Jersey — What We Know, What We Test, Who We File With
🔹 Pressure Vacuum Breakers (PVB)
The standard backflow device on the vast majority of New Jersey residential and commercial in-ground irrigation systems. Required under N.J.A.C. 7:14B for standard irrigation cross-connections where contamination risk is elevated pressure applications. Installed at or above grade at the irrigation system's point of connection. The single most common device type in an irrigation contractor's client base.
🔸 Reduced Pressure Zone (RPZ) Assemblies
Required when irrigation systems include chemical injection — fertilizer injection, pesticide injection, or other fertigation connections. RPZ assemblies provide the highest level of backflow protection and are required under N.J.A.C. 7:14B's high-hazard cross-connection classification for any connection where chemical contamination is possible. If any of your clients have fertigation systems, every one of those systems has an RPZ requirement. See when an RPZ is required in NJ for the full regulatory breakdown.
🔹Atmospheric Vacuum Breakers (AVB)
Used in specific low-hazard irrigation applications, primarily on individual zone valves in non-pressure situations. Less common than PVBs but still present in older system designs throughout New Jersey.
🔸 Double Check Valve Assemblies (DCDA)
Present on some commercial irrigation systems, particularly in municipalities or water authorities with specific cross-connection control requirements for non-residential irrigation connections.

Common Questions
Frequently Asked Questions From New Jersey Irrigation Companies
Will you market irrigation services to my clients directly?
No — never. We are not an irrigation company. We do not install systems, service heads, adjust controllers, or perform any irrigation work. When we are on-site at one of your clients' properties, we complete the annual backflow test and nothing else. We do not hand out South Jersey Backflow marketing materials, we do not suggest irrigation services to your clients, and we do not attempt to establish any direct service relationship. The irrigation relationship belongs to you.
What happens when a device fails and needs to be replaced?
If a pressure vacuum breaker or RPZ assembly is beyond cost-effective repair, we document the finding in our written test report and send the referral directly to you — device type, size, location, address, client contact, and urgency. We tell the client that their irrigation contractor handles device replacement. We do not offer to source or install the replacement device ourselves. That job is yours.
Can you coordinate with our spring startup schedule?
Yes — this is one of the most practical benefits of the sub-contractor arrangement. We can schedule annual backflow testing visits to align with your spring startup visits, arriving at properties the same day as or immediately following your startup crews. This eliminates a second scheduling conversation with the client and allows your company to present spring startup and annual backflow compliance as a single cohesive seasonal service. Contact us to discuss how to structure scheduling coordination for your spring season.
How do the Net-30 and Net-60 terms work for new accounts?
All new irrigation sub-contractor accounts start on Net-30 billing — payment due 30 days from invoice date. After 90 days of account history in good standing, any account can request Net-60 terms and we extend them without additional qualification requirements. For larger irrigation companies enrolling significant client bases from the start, Net-60 terms can often be arranged immediately — contact us to discuss. No credit application, no personal guarantee, no fee.
