CPVC-Connected Washing Machine Drain Box with Stainless Steel Water Hammer Arrestor

This product is an integrated protective outlet solution specifically designed for CPVC piping systems. It innovatively combines a 316 stainless steel water hammer arrestor with a CPVC solvent welded fitting, creating a triple-protection system that resists corrosion, prevents leaks, and eliminates noise.

The main body is injection-molded from reinforced CPVC material, offering chlorine and high-temperature resistance that perfectly complements the piping system. The built-in 316 stainless steel water hammer arrestor combines a precision pre-charged nitrogen chamber with a polymer diaphragm to instantly dissipate shock waves generated by the rapid start/stop cycles of washing machines. This effectively suppresses over 93% of piping noise and protects fittings and electrical appliances from water hammer damage.

Featuring CPVC solvent-welded joints, it forms a molecular-level fusion seal with CPVC pipes using specialized adhesive, completely eliminating joint leakage risks. The housing integrates hot/cold water valve seats, a large-diameter drain outlet, and electrical wiring ports. All functional units employ leak-proof structural design for long-term safety.

Ideal for corrosive environments like high-chlorine water or coastal areas, and laundry rooms requiring permanent leak-proof connections.
