## Summary description

ARCO model 191203 is a mushroom-type check valve with anti-scale design, featuring 1/2" female BSP connections on both ends.

Suitable for residential and light commercial water systems and heating circuits where compact non-return protection is required.

## Long description

The ARCO 191203 mushroom anti-scale check valve is a compact non-return valve designed for installation in water and heating systems. It features female 1/2" BSP connections on both ends and a mushroom (disc) internal closing element that allows one-way flow while helping to reduce scale buildup. The valve is intended for residential and light commercial applications where a small, reliable check valve is required to prevent backflow and protect piping and equipment.
Advantages
The mushroom-style internal element provides reliable sealing under typical system pressures while its anti-scale design reduces the rate of mineral accumulation on the closing surface. Its compact form factor and identical female BSP connections on both ends simplify inline replacements and installation in confined spaces. The valve construction supports standard plumbing connections and offers consistent one-way flow control with minimal maintenance.
Suitable for
 Domestic cold and hot water installations
 Heating circuits and radiators
 Compact pump discharge lines requiring backflow prevention
 Light commercial water systems and service loops

 Function: one-way non-return valve with anti-scale features

How to use
Install the check valve in the pipe run with the flow direction matching the arrow indicated on the valve body. Use compatible 1/2" female BSP fittings or adapters to connect to the existing piping. Ensure threaded joints are sealed according to standard plumbing practice and that the valve is accessible for inspection. The valve operates automatically; no external power or manual actuation is required. Periodic inspection is recommended in hard water conditions to verify the internal sealing surface remains clear of excessive deposits.
Usage recommendations
For reliable operation, install the valve in locations protected from freezing and where the flow is within the system's normal pressure and temperature ranges. In areas with hard water, consider routine inspection intervals to check for scale; if heavy deposits occur, follow local guidelines for safe descaling or replace the valve to maintain one-way performance.
