Mini-Max Laundry with Arrestors

MM-500PLB - MM-500MLB

Precision Plumbing Products has designed a plastic/metal Laundry box assembly that makes your application simple and cost effective.

Solenoid operated laundry equipment can create destructive water hammer due to quick closing valves on the fill cycle. Water hammer can damage or even break your hose connections as well as destroy the solenoid valve.

To avoid this common household problem hook your washing machine hose connectors to the quarter turn ball valve in our laundry box assembly with water hammer arrestors and rest easy.
