It incorporates an air-tight air chamber with a piston with (2) o-rings, which effectively separates a pressurized cushion of air from the water system and prevents the air charge from being lost. Certified by ASSE to the ANSI/ASSE 1010-2004 Standard.

Can be installed at any angle
No access panel required for installing behind sealed wall
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.
