Product Identity

The Jay R. Smith Mfg. Co 520-T-B is a water hammer arrestor designed for light commercial plumbing systems. It uses a copper body with threaded connections to absorb pressure surges in 3/4 inch piping. The unit is factory set at 60 psi and rated for a maximum pressure of 350 psi.

Suitability

This arrestor suits installers who need a code-compliant device for copper piping in commercial bathware applications. It operates across a temperature range of 33 to 250 degrees Fahrenheit. Buyers requiring a different pipe diameter or a sweat connection type should look at other models. The product is not intended for residential-only installations that specify alternative standards.

Ensure the 8 11/16 inch overall height and 1 25/64 inch diameter fit within the available cavity space. Check local codes for ASSE 1010 acceptance and lead plumbing law compliance.
