River City Backflow Specialist is your one call solution when it comes to anything backflow related. We diagnose, troubleshoot, repair, replace, test and certify a full-range of backflow prevention assemblies.

When most people hear about backflow or see backflow assemblies, they usually have no clue what it is, how it works, or how it can affect your public or personal drinking water supply.  River City Backflow Specialist wants to change that by bringing awareness to the community through education & shining a light on the hidden dangers and hazards of cross-connections and backflow conditions.

We also perform cross-connection control site survey’s to determine the degree of hazards you may have and designate the type of backflow prevention measures to take or the type of backflow assemblies needed to keep your personal water system safe from all undesirable backflow conditions.

Because water is such an essential resource & one of our most poorly managed resources, it is important to be aware of backflow, cross-connection hazards and potential dangers that can effect your health. Through these preventative awareness measures, we can successfully protect our water supply safely and effectively.

Important Notice:

Please do not let anyone tell you your backflow prevention assembly needs to be replaced (unless taken out by a vehicle, destroyed by freeze or fire). There are times that the epoxy coating inside the larger assemblies fail and allow for our hard water to destroy the metal bodies these assemblies are made of, or the manufacturer of the assembly made it so that some crucial part were not replaceable, like some of the older Febco models. Most backflow prevention assemblies though are designed to be repaired. The cost of the repair kits are minimal compared to the cost of replacing the entire assembly. I see all too often that a plumber or backflow technician talks the customer into spending hundreds more than needed.

Please call us first to come out to troubleshoot and diagnose your backflow prevention assembly. If anyone can save your backflow prevention assembly and your money, I can.


R18-4-215.Backflow Prevention

  1. A public water system shall protect its system from contamination caused by backflow through unprotected cross-connections by requiring the installation and periodic testing of backflow-prevention assemblies. Required backflow-prevention assemblies shall be installed as close as practicable to the service connection.
  2. A public water system shall ensure that a backflow-prevention assembly is installed whenever any of the following occur:
  3. A substance harmful to human health is handled in a manner that could permit its entry into the public water system. These substances include chemicals, chemical or biological process waters, water from public water supplies that has deteriorated in sanitary quality, and water that has entered a fire sprinkler system. A Class 1 or Class 2 fire sprinkler system is exempt from the requirements of this Section;
  4. A source of water supply exists on the user’s premises that is not accepted as an additional source by the public water system or is not approved by the Department;
  5. An unprotected cross-connection exists or a cross-connection problem has previously occurred within a user’s premises; or
  6. There is a significant possibility that a cross-connection problem will occur and entry to the premises is restricted to the extent that cross-connection inspections cannot be made with sufficient frequency or on sufficiently short notice to ensure that unprotected cross-connections do not exist.
  7. Unless a cross-connection problem is specifically identified, or as otherwise provided in this Section, the requirements of this Section shall not apply to single-family residences used solely for residential purposes.
  8. A backflow-prevention assembly required by this Section shall comply with the following:
  9. If equipped with test cocks, it shall have been issued a certificate of approval by:
  10. The University of Southern California Foundation for Cross-Connection Control and Hydraulic Research (USC-FCCCHR), or
  11. A third-party certifying entity that is unrelated to the product’s manufacturer or vendor, and is approved by the Department.
  12. If not equipped with test cocks, it shall be approved by a third-party certifying entity that is unrelated to the product’s manufacturer or vendor and is approved by the Department.
  13. The minimum level of backflow protection that is provided to protect a public water system shall be the level recommended in Section 7.2 of the Manual of Cross-Connection Control, Ninth Edition, USC-FCCCHR, KAP-200 University Park MC-2531, Los Angeles, CA, 90089-2531, December 1993, (and no future editions or amendments), incorporated by reference and on file with the Department. The types of backflow prevention that may be required, listed in decreasing order according to the level of protection they provide, include: an air-gap separation (AG), a reduced pressure principle backflow prevention (RP) assembly, a pressure vacuum breaker (PVB) assembly, and a double check valve (DC) assembly. Nothing contained in this Section shall prevent a public water system from requiring the use of a higher level of protection than the level required by this subsection.
  14. A public water system may make installation of a required backflow-prevention assembly a condition of service. A user’s failure to comply with this requirement shall be sufficient cause for the public water system to terminate water service.
  15. Specific installation requirements for backflow prevention include the following:
  16. Any backflow prevention required by this Section shall be installed in accordance with the manufacturer’s specifications.
  17. For an AG installation, all piping between the user’s connection and the receiving tank shall be entirely visible unless otherwise approved in writing by the public water system.
  18. An RP assembly shall not be installed in a meter box, pit, or vault unless adequate drainage is provided.
  19. A PVB assembly may be installed for use on a landscape water irrigation system if the irrigation system conforms to all of the criteria listed below. An RP assembly is required whenever any of the criteria are not met.
  20. The water use beyond the assembly is for irrigation purposes only;
  21. The PVB is installed in accordance with the manufacturer’s specifications;
  22. The irrigation system is designed and constructed to be incapable of inducing backpressure; and
  23. The injection of chemical pesticides and fertilizers, chemigation, is not used or provided in the irrigation system.
  24. Each backflow-prevention assembly required by this Section shall be tested at least annually, or more frequently if directed by the public water system or the Department.

The following provisions shall apply to the testing of backflow-prevention assemblies:
  25. Testing shall be in accordance with procedures described in Section 9 of the Manual of Cross-Connection Control. The public water system shall notify the water user when testing of backflow-prevention assemblies is needed. The notice shall specify the date by which the testing must be completed and the results forwarded to the public water system.
  26. Testing shall be performed by a person who is currently certified as a “general” tester by the California-Nevada Section of the American Water Works Association (CA-NV Section, AWWA), the Arizona State Environmental Technical Training (ASETT) Center, or other certifying authority approved by the Department.
  27. When a backflow-prevention assembly is tested and found to be defective, it shall be repaired or replaced in accordance with the provisions of this Section.
  28. A public water system shall maintain records of backflow-prevention assembly installations and tests performed on backflow-prevention assemblies in its service area. Records shall be retained by the public water system for at least three years and shall be made available for review by the Department upon request. These records shall include an inventory of backflow-prevention assemblies required by this Section and, for each assembly, all of the following information:
  29. Assembly identification number and description,
  30. Location,
  31. Date of tests,
  32. Description of repairs and recommendations for repairs made by the tester, and
  33. The tester’s name and certificate number.
