FAQs
What is backflow and why is regular testing essential for Mulberry commercial properties?
Backflow is the unwanted reversal of water flow that can allow contaminants—fertilizers, chemicals, or bacteria—to enter the public drinking-water system. Commercial buildings in Mulberry typically have complex plumbing with cross-connections to lawn sprinklers, boilers, fire-suppression lines, or manufacturing processes, all of which increase the risk. Regular testing verifies that the backflow prevention assembly is functioning correctly and keeps your employees, customers, and the wider community safe.
How often does Florida and Polk County require my business to have its backflow preventer tested?
State plumbing code and Polk County Utilities regulations require most commercial backflow prevention devices to be tested annually. Some high-hazard sites such as restaurants, medical facilities, and industrial plants may be required to test more frequently or after any repair or relocation of the assembly. Our team tracks your testing schedule and provides reminders so you remain in full compliance.
What is included in your commercial backflow testing service?
Our certified tester arrives on-site with calibrated gauges, shuts off the water for only a few minutes, records differential pressure readings, and inspects each check valve, relief valve, and shut-off valve. We clean and lubricate the device if minor debris is found, complete the Polk County test report, affix a dated certification tag to the assembly, and email you digital copies for your records—usually in less than an hour per device.
What happens if my backflow device fails the test?
If the assembly does not meet performance standards, we immediately inform you, explain the problem, and provide a written repair or replacement estimate. In most cases we can perform same-day repairs by rebuilding internal parts kits stocked on our service trucks. After repairs, we retest the unit at no extra charge and file the passing report with the county so you avoid fines or service shut-offs.
Are your technicians qualified to test all types and sizes of backflow preventers?
Yes. Our plumbers hold current State of Florida Backflow Prevention Assembly Tester (BPAT) certifications and carry Polk County registration. We test and repair double-check, reduced-pressure principle, pressure vacuum breaker, and spill-resistant vacuum breaker assemblies from ¾-inch irrigation units up to 10-inch fire-line devices. We stay updated on manufacturer specifications and keep OEM parts in stock to minimize downtime.
Will backflow testing disrupt my business operations, and how do I schedule an appointment?
Testing usually requires a brief water shut-off of 5–15 minutes per device. We can perform the work before or after business hours, during shift changes, or on weekends to minimize impact on production and customer service. Simply call our Mulberry office, use the online scheduler, or email your preferred date and time. We provide confirmation within one business day and send a technician equipped with all necessary tools and paperwork.
