Service Overview
Backflow Testing Backed by 65+ Years of Local Experience
Backflow testing is a state and local requirement designed to protect the public drinking water supply from contamination. When water pressure drops or reverses — due to a water main break, high demand, or system failure — untreated water from irrigation systems, fire suppression lines, or industrial equipment can flow backward into the potable water supply. Florida law requires that backflow prevention assemblies on commercial, residential irrigation, and other high-hazard connections be tested annually by a certified tester. Failing to comply can result in service interruptions, fines, or violations from your local water utility.
Lapin Services is a licensed plumbing contractor (CFC1428594) with certified backflow testers serving Orlando and all of Central Florida. Our technicians are trained to test all types of backflow prevention assemblies — reduced pressure zone (RPZ), double check valve, pressure vacuum breaker, and more — in full accordance with county, municipal, and state requirements. We document every test on the required form, identify any repair needs if a device fails, and submit results to the appropriate authority on your behalf. With 65+ years serving Central Florida and a 4.9★ rating from over 1,000 customers, we make compliance straightforward and stress-free.
Problems We Solve
Common Backflow Testing Problems We Fix
Here are the issues our team commonly finds and resolves during backflow testing calls across Central Florida.
Annual Compliance Deadline Approaching
Florida water utilities require annual backflow preventer testing on commercial properties, multi-family housing, and residential irrigation systems. Missing the deadline can result in notices of violation, service interruption, or fines — a certified test from Lapin keeps you on the right side of your utility and local code.
New Construction or Permit Inspections
Newly installed irrigation systems, fire lines, or commercial plumbing connections often require a certified backflow test before a permit can be closed or a certificate of occupancy issued. Lapin works directly with inspectors to ensure your device is tested, documented, and approved without delaying your project timeline.
Property Sale or Transfer
Buyers, lenders, or their inspectors frequently request proof that backflow prevention assemblies are functional and up to date. A current certified test report from Lapin gives buyers confidence and keeps the transaction moving forward without last-minute compliance surprises.
Notice of Violation or Failed Previous Test
If your backflow preventer failed a previous test or you've received a violation notice from your utility, the clock is ticking. Lapin performs the test, identifies the deficiency, and can repair or replace the failing assembly — getting you back into compliance as quickly as possible.
Commercial Tenant Turnover or Renovation
Changes to plumbing systems during a commercial build-out or tenant change-over often trigger new backflow testing requirements. Lapin works alongside general contractors and property managers to ensure backflow devices are tested at the right point in the project and that all documentation is properly filed.
When to Call
Signs Your Plumbing System Needs Professional Attention
If you notice any of these warning signs, schedule backflow testing before the problem becomes more disruptive or expensive.
You Received a Test Notice from Your Water Utility
Water utilities in Orange, Osceola, Seminole, and surrounding Central Florida counties send annual test notices to property owners with registered backflow prevention assemblies. If you've received a notice, your test window is open — contact Lapin to schedule before the deadline to avoid service interruptions.
Your Property Has an Irrigation System
Residential and commercial irrigation systems connected to potable water lines are required by Florida law to have a backflow preventer, and that device must be tested annually. If your lawn or landscape is on an in-ground irrigation system and you haven't had a test this year, it's time to schedule one.
You Operate a Commercial or Food-Service Facility
Restaurants, car washes, medical offices, laundromats, and other commercial facilities with cross-connection risk require certified backflow testing as a condition of their water service. Compliance protects your business from liability — and from the health risk of contaminated water reaching your customers or staff.
You Notice Discolored, Odorous, or Strange-Tasting Water
Unusual water quality at your tap can be a sign that backflow has already occurred and contaminants have entered your supply line. This is an emergency — stop using the water and call Lapin immediately. We'll inspect your backflow prevention assembly and coordinate with your utility as needed.
Your Backflow Preventer Has Never Been Tested or Is Overdue
If you're unsure when your backflow preventer was last tested — or if you've owned the property for several years without a test on record — it's overdue. Lapin can locate your device, assess its condition, and perform a certified test to bring you current and on record with your utility.

FAQs
Backflow Testing FAQs
How often is backflow testing required in Florida?
Florida requires backflow prevention assemblies to be tested at least once per year by a certified tester. Your local water utility — whether it’s Orange County Utilities, the City of Orlando, OUC, or another provider — will typically send an annual test notice. Missing the deadline can result in a notice of violation or interruption of water service.
What types of backflow preventers does Lapin test?
Our certified technicians test all common backflow prevention assembly types, including reduced pressure zone (RPZ) assemblies, double check valve assemblies (DCVA), pressure vacuum breakers (PVB), spill-resistant pressure vacuum breakers (SVB), and atmospheric vacuum breakers (AVB). If you’re unsure what type of device you have, we can identify it when we arrive on site.
What happens if my backflow preventer fails the test?
If your device fails, it must be repaired or replaced before it can pass re-testing. Lapin can handle the repair or replacement on the spot in many cases, or schedule a follow-up service visit quickly. We document the failure, complete the required repair, re-test the assembly, and submit the passing report to your utility — all under one contractor, with no need to coordinate multiple vendors.
Do I need to be home for the backflow test?
For most irrigation system backflow preventers, the device is located outside and accessible without entry to the home — so you typically don’t need to be present. For commercial properties or devices located inside a mechanical room, access coordination may be required. We’ll confirm the access requirements when you schedule your appointment.
Will Lapin submit the test report to my water utility?
Yes. Submitting the test report to the appropriate water authority is part of our service. We complete the required documentation, file it with your utility on your behalf, and provide you with a copy for your records. You don’t need to handle any paperwork yourself.
Does my residential home need a backflow test?
Residential properties with in-ground irrigation systems connected to the municipal water supply are typically required to have an annual backflow test in Central Florida. Homes on private wells with irrigation are subject to different rules. If you’ve received a test notice from your utility, a test is required. If you’re unsure whether your property is subject to testing requirements, call Lapin and we’ll help you determine your obligations.
How long does a backflow test take?
A standard backflow preventer test typically takes 20 to 45 minutes, depending on the device type, its location, and whether any issues are found during the test. If a repair is needed, additional time will be required. We’ll give you a realistic time estimate when we schedule your appointment.
How do I know where my backflow preventer is located?
On residential properties, backflow preventers for irrigation systems are usually located near the water meter, at the point where the irrigation line branches from the main water supply — often close to the foundation or near the meter box. On commercial properties, devices may be in a mechanical room, utility closet, or near the water service entry. If you can’t locate yours, our technician will find and identify it when they arrive.
