Installing an RPZD to Protect the Drinking Water Supply
Silver Drains & Plumbing recently installed a Reduced Pressure Zone Device (RPZD) in accordance with the relevant compliance requirements to protect the property's drinking water supply.
The new device helps prevent contaminated water from flowing back into the public water network, providing an essential safeguard where there is an increased risk of backflow.
What Is Backflow?
Backflow occurs when water flows in the opposite direction to normal.
Instead of clean drinking water travelling from the mains supply into a property, a sudden change in water pressure can cause water from the property's plumbing system to be drawn backwards towards the public water supply.
If that water has come into contact with chemicals, irrigation systems, industrial equipment or other contaminants, it has the potential to affect the quality of the drinking water network.
Backflow prevention devices are installed to eliminate that risk.
Why Is an RPZD Required?
An RPZD is one of the highest levels of backflow protection available and is typically required where a property presents a high hazard to the public water supply.
These devices are commonly installed on:
-
Commercial properties
-
Medical facilities
-
Industrial buildings
-
Irrigation systems
-
Fire protection systems
-
Some specialised residential plumbing systems
The exact requirements depend on the property's plumbing installation and the local water authority's regulations.
Installation Is Only Part of the Process
Correct installation is essential, but ongoing maintenance is equally important.
RPZD devices are precision mechanical valves that contain internal components designed to operate under specific pressure conditions. Over time, normal wear can affect their performance, which is why they must be tested at regular intervals by an accredited backflow plumber.
Routine testing confirms the device continues to protect both the property and the wider community's drinking water supply.
