What Is Backflow Prevention and Why Does It Matter?
Backflow prevention protects Mesa’s drinking water supply from contamination by stopping water from flowing backward into the potable water system. When backflow occurs, contaminated water from irrigation systems, chemical tanks, or other sources can reverse direction and enter the clean water you drink, cook with, and bathe in.
Backflow happens in two ways. Back-siphonage occurs when negative pressure in the water main pulls contaminated water backward, similar to drinking through a straw. Backpressure happens when higher pressure on your property forces water backward into the public water supply, common with boiler systems, fire suppression systems, and elevated irrigation lines.
A backflow preventer is a specialized valve assembly that allows water to flow in only one direction. When installed at cross-connection points where contaminated water could enter your potable water, these devices create a physical barrier that prevents reverse flow. Mesa city code requires backflow prevention devices on properties with sprinkler systems, commercial kitchens, fire systems, and other high-risk cross-connections.
Annual testing by certified backflow testers ensures your device functions properly. We test shut-off valves, check valves, and relief valves to verify complete protection. Our licensed testers file certification paperwork with the City of Mesa Water Resources Department, keeping your property compliant.
Types of Backflow Prevention Devices We Install and Service
Not all backflow preventers are the same. Mesa requires specific device types based on your property’s cross-connections and hazard level. Our certified testers recommend and install the correct backflow assembly for your situation.
RPZ Valve (Reduced Pressure Zone)
The RPZ valve provides maximum protection for high-hazard applications like commercial kitchens, fire sprinkler systems, and chemical injection systems. This backflow device features two independent check valves with a relief valve between them that dumps water if backflow is detected, making it Mesa’s most reliable protection.
Double Check Valve Assembly
Double check valves use two spring-loaded check valves in series to prevent backflow in medium-hazard situations like residential irrigation systems and commercial buildings. This backflow preventer costs less than RPZ assemblies and works well where contamination risk is lower, but the Mesa code still requires protection.
Pressure Vacuum Breaker (PVB)
PVB devices protect against back-siphonage in residential sprinkler systems and lawn irrigation. The device opens a relief valve when pressure drops, allowing air in to break the siphon. Mesa commonly requires PVBs for home irrigation systems, and they must install above all downstream piping.
Atmospheric Vacuum Breaker (AVB)
The simplest backflow preventer, AVB devices protect individual fixtures like irrigation hose bibs and outdoor faucets from back-siphonage. These non-testable devices cost less but only work on fixtures without continuous pressure. Mesa properties often use AVBs on secondary outdoor water connections for basic protection.

3
Install Device to Code Specifications
Our licensed plumbers install your backflow preventer at the correct height, distance from walls, and accessibility for annual testing. We ensure proper drainage, clearances, and protection from freezing per Mesa installation standards.
4
Test and Submit Certification
After installation, we perform comprehensive testing of all check valves, relief valves, and test cocks. We file your certification with the City of Mesa Water Resources Department and provide you with documentation for your records.
Whether it’s a midnight pipe burst or a complete plumbing system installation, our certified team is ready to help.
Why Backflow Prevention Matters in Mesa?
Backflow prevention isn’t optional; it’s essential for protecting public health, meeting Mesa city code, and avoiding serious legal and financial consequences. Here’s why every property owner needs to take backflow seriously.
- Protects your family’s health from dangerous contamination like pesticides, fertilizers, bacteria, and chemicals that can enter your drinking water through backflow.
- Required by Mesa city ordinance for properties with irrigation systems, fire sprinklers, commercial kitchens, and other cross-connections to the public water supply.
- Annual testing is mandatory for most backflow devices in Mesa, and failing to test on time results in fines, water shut-offs, and compliance violations.
- Prevents citywide water contamination that could affect your entire neighborhood when your property’s backflow pushes pollutants into Mesa’s water main.
- Protects you from liability if contaminated water from your property harms neighbors or violates public health codes; fines can reach thousands of dollars.
- Maintains property value and insurability since non-compliant properties face difficulties during sales, refinancing, and commercial property insurance renewals when backflow certification lapses.

Yes, if you have an irrigation system, fire sprinkler, commercial kitchen, or other cross-connections. Mesa city ordinance requires backflow prevention devices on properties where contaminated water could enter the public water supply. Operating without one violates health codes and risks fines.
No. Mesa requires testing by certified backflow testers who hold state certification. DIY testing isn't accepted for city compliance. Our licensed testers have the proper equipment, training, and credentials to perform valid tests and file official certifications with the city.
RPZ valves provide maximum protection for high-hazard situations like commercial kitchens and chemical systems. Double check valves work for medium-hazard applications like residential irrigation. RPZ assemblies cost more but offer superior protection through their relief valve design that actively dumps contaminated water.
