Product information

Description

ARCO anti-pollution valve model 191104 features 3/4" female inlet and 3/4" female outlet connections and is designed to prevent backflow and protect potable water systems from contamination. The valve is intended for installation in household and small commercial water lines where cross-connections or pressure changes could allow contaminated water to enter the drinking supply. Its compact design fits standard 3/4" fittings and provides a reliable barrier against reverse flow without altering normal forward flow under typical operating conditions.

Advantages

The valve provides mechanical backflow prevention that reduces the risk of contaminants entering the potable water system. Its 3/4" female-to-female configuration allows direct integration with common domestic plumbing fittings. The device is compact and suitable for inline installation, offering continuous protection with minimal maintenance. Constructed for routine water installations, it operates automatically and does not require electrical power or complex adjustments.

Suitable for

  • Protection of domestic drinking water lines from cross-connections
  • Irrigation systems where return flow could contaminate the supply
  • Small commercial water lines requiring basic backflow prevention
  • Inline installations with standard 3/4" female fittings

Key specifications

  • Connection type: 3/4" female thread on inlet and outlet
  • Function: anti-pollution / backflow prevention valve
  • Application: potable water systems in residential and small commercial installations
  • Installation: inline, between supply and downstream plumbing
  • Operation: automatic mechanical action, no electrical supply required

How to use

Install the valve in the water line using compatible 3/4" female threaded fittings, ensuring correct flow direction according to the valve markings. Secure connections with appropriate sealing materials and tighten to the manufacturer's recommended torque for threaded plumbing joints. After installation, open the supply slowly and check for leaks; verify proper forward flow and the absence of reverse flow during normal operation. Periodically inspect the valve and surrounding fittings for signs of leakage or wear and service or replace as necessary.

Usage recommendations

Use the ARCO anti-pollution valve in systems where basic backflow protection is required. For installations exposed to freezing temperatures, ensure the valve and surrounding piping are protected against freeze damage. Follow local plumbing codes for backflow prevention and consult a qualified plumber for installations that require higher-level backflow devices or certifications.
