## Long description

FERRO anti-backflow valve EA 1" ZZA03 is a mechanical backflow prevention valve designed for potable water systems. Intended for installation on 1-inch pipelines, the valve maintains unidirectional flow to protect the water supply from contamination caused by reverse flow. The device is suitable for residential and light commercial plumbing installations where a compact, reliable anti-backflow solution is required.

Domestic potable water supply lines

Key specifications
Connection size: 1 inch (suitable for standard 1" pipes)
Function: mechanical non-return / anti-backflow operation
Intended medium: potable (drinking) water
Typical installation: inline on horizontal or vertical sections of pipe where indicated by plumbing codes
Compact form factor designed for residential and light commercial use
How to use
Install the valve in the pipeline in the correct orientation so that the marked flow direction matches the supply flow. Follow local plumbing regulations and use compatible fittings and sealing materials for a leak-free connection. After installation, test the line by opening the supply and verifying that flow passes only in the forward direction and that no reverse flow occurs when downstream pressure conditions change. Periodically inspect for leaks or excessive wear and service or replace the valve if its mechanical components become compromised.
Usage recommendations
Use the FERRO anti-backflow valve on potable water lines only and ensure it is accessible for inspection and maintenance. Avoid exposure to freezing conditions and do not use with aggressive chemicals or non-potable fluids. When used in systems with pumps or frequent pressure fluctuations, schedule regular inspections to confirm continued functionality.
