Because backflow devices are critical to maintaining clean, safe water supplies, California State Water Districts, County Health Boards and Local Municipalities regulations mandate that only licensed and certified backflow technicians and plumbers who have the expertise, training, have the legal authority to perform repairs or replacements in compliance with regulations and with the necessary quality control to protect the public water system.
Failing to comply with the regulations may result in fines or suspension of water service. It is important for Cypress homeowners and businesses to stay up-to-date with local regulations and to ensure that their backflow devices are tested annually by a certified tester.
The City of Cypress, in collaboration with the Orange County Health Care Agency (OCHCA), enforces a Cross-Connection Control and Backflow Prevention Program to protect its potable water supply from contamination due to backflow incidents.
This program complies with the California Code of Regulations, Title 17, and mandates the installation and maintenance of approved backflow prevention assemblies (BPAs) at service connections where potential hazards are identified.
Cypress property owners are responsible for ensuring that backflow prevention devices are installed properly and meet local and state regulations. Backflow prevention devices must be installed following Plumbing and Building Code as well as California's State Building Standards.
Cypress property owners must also hire a certified backflow tester to perform annual tests on their devices. All backflow prevention devices must be tested annually by a certified backflow prevention tester to ensure that they are working correctly. Only individuals with a valid Certified Backflow Prevention Device Tester (C.B.P.D.T.) certification can conduct these tests.
Aslo, backflow test results must be submitted to the City of Cypress Public Works Department. If the test results are not submitted on time, a penalty fee may be charged, and water service may be temporarily suspended.
Backflow device maintenance is also an important element of Cypress property owner's responsibilities. Homeowners and businesses are required to keep backflow prevention devices in good working order. If a backflow device fails the test, it must be repaired or replaced immediately.

- Backflow Prevention: To prevent the reverse flow of water that could introduce pollutants or contaminants into the public water system.
- Cross-Connection Control: To eliminate or safeguard against connections between potable and non-potable water systems, ensuring the safety of drinking water.
Cypress requires the installation of approved backflow prevention devices at locations where there is a potential risk of contamination. These devices must be installed at or near the property line or immediately outside the building being served, before the first branch line leading off of the service line.
Cypress's water system is managed by the City's Public Works Department, which enforces backflow prevention measures in accordance with:
- Cypress Municipal Code: Outlines the requirements for building regulations, including backflow prevention.
- Title 17, California Code of Regulations: Defines cross-connection control program responsibilities for public water systems.
Cypress's regulations require the installation of approved backflow prevention assemblies (BPAs) to protect the water supply. Backflow prevention assemblies are required in various scenarios, including:
- Cypress Property Irrigation Systems: To prevent contaminants from entering the potable water supply through irrigation lines.

Property owners are responsible for installing backflow prevention assemblies as required by the city's regulations or or OCHCA. Installations must adhere to the city's standards, including specific device types and installation procedures.
Failure to install the required backflow prevention assemblies in compliance with Cypress regulations and requirements may result in the discontinuation of water service until compliance is achieved.
