## Long description

Honeywell RV284-3/4A is an anti-contamination check valve with a 3/4" internal thread designed to prevent backflow in potable water systems. The valve fits inline on supply pipes and allows flow in one direction while blocking reverse flow to protect drinking water from contamination. Its compact body and female threaded connection make it suitable for installation in domestic and light commercial plumbing systems where reliable backflow prevention is required.
Advantages
The check valve provides a straightforward mechanical solution to stop reverse flow without the need for an external power source. Its internal 3/4" threaded connection enables direct coupling to common plumbing fittings and reduces the need for additional adapters. The compact design simplifies placement in confined pipe runs and helps maintain system integrity by reducing the risk of contamination due to backflow.
Suitable for
Domestic potable water supply lines
Light commercial plumbing installations
Inline protection against backflow and cross-contamination
Replacement of existing inline check valves with female threaded connections
Key specifications
Connection type: 3/4" internal (female) thread
Function: anti-contamination / one-way check valve
Installation: inline on supply pipe
Application: potable water systems
Design: compact body for restricted spaces
How to use
Shut off the water supply before installing the valve. Thread the valve into a compatible 3/4" male threaded fitting or adapter, ensuring the flow direction marked on the body aligns with the intended supply flow. Tighten using appropriate tools without over-torquing to avoid damaging threads or the valve body. After installation, slowly reopen the supply and check for leaks; ensure the valve allows forward flow and prevents reverse flow during system operation.
Usage recommendations
Install the valve in an accessible location for periodic inspection. Use thread sealant or tape compatible with potable water systems on male threads to ensure a watertight joint. Do not expose the valve to freezing conditions when filled with water; drain or insulate exposed pipework. For systems with high particulate content, consider upstream filtration to avoid premature valve wear or blockage.
