Backflow Prevention Rondebosch | RPZ & Check Valve Installation

About Backflow Prevention in Rondebosch

Backflow prevention protects your drinking water from contamination caused by reverse flow in your plumbing system. When pressure drops in the municipal supply, water can flow backwards from irrigation systems, pools, boilers, or other non-potable sources into your clean water lines. This is a serious health hazard, and South African regulations require backflow prevention devices on all cross-connections.

Abacas Solution installs, tests, and maintains backflow prevention devices throughout Rondebosch. We work with all device types: reduced pressure zone (RPZ) assemblies for high-hazard applications, double check valves for medium-risk connections, and atmospheric vacuum breakers for irrigation and hose bibs. The type of device required depends on the level of hazard and the application, and we ensure the correct device is installed for your specific situation.

Properties with irrigation systems connected to the municipal supply, swimming pools with autofill connections, commercial kitchens, and any property with chemical dosing systems all require appropriate backflow prevention. We also perform annual testing and certification of RPZ devices, which is mandatory for commercial installations. Our installations comply with SANS 10252 and local municipal regulations, and we provide compliance documentation for your records.

This is one of several specialist services we offer under water systems & pressure in Rondebosch. As part of our Rondebosch plumbing team, we bring over 25 years of hands-on experience to every job.

Frequently Asked Questions

Does my irrigation system in Rondebosch need a backflow preventer?

Yes. Any irrigation system connected to the municipal water supply must have backflow prevention. Fertilisers, pesticides, and soil bacteria in irrigation lines can contaminate your drinking water if backflow occurs during a pressure drop. We install the appropriate device based on whether you use chemical injection (requires RPZ) or just standard watering (may only need a vacuum breaker).

What is an RPZ valve and why is it more expensive?

An RPZ (Reduced Pressure Zone) assembly is the highest level of backflow protection. It contains two check valves and a relief valve that dumps water if either check valve fails, guaranteeing contaminated water never reaches the clean supply. It is required for high-hazard connections like chemical dosing, commercial kitchens, and certain pool connections. The cost reflects the precision engineering and annual testing requirement.

How often does a backflow prevention device need testing in Rondebosch?

RPZ assemblies require annual testing and certification by a qualified tester. Double check valves should be tested every 1-2 years. Vacuum breakers should be visually inspected annually. We provide testing services and can set up an annual maintenance schedule for your Rondebosch property. We issue test certificates for your records.
