About Water Hammer Arrestors
Water hammer arrestor, or “arresters” is a mechanical device designed to protect the plumbing system from the “water hammer effect”, caused by rapid closing of the water valve. This effect creates sudden spike in water pressure, which stresses the piping joints and systems' components and may cause them to fail or malfunction. Simplistic design of the water hammer arrestor incorporates an air chamber with a lubricated piston which acts like a cushion, compensating the sudden water pressure surges.
Sioux Chief water hammer arrestor incorporates a corrosion-resistant preformed copper chamber and a lead-free brass fitting (on select models). These units are well-built, second to none in quality and reliability and have been proven to outlast and outperform conventional air chambers. UPC/IPC listing and ASSE certification, together with a large variety of connections options, allow to install these arrestors both in existing and new construction where quick-closing or quater-turn shut-off valves are used.

Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
