Title: This is a LOW FLOW regulator don't use for whole house
Product review: There is no manufacturer specification from Sharkbite or the regulator valve company CASH ACME. While the valve is 3/4" pipe size, it can NOT be used as a whole house (main) regulator. It restricts the flow and makes a chatter (vibration) if you run a lawn sprinkler or use other high water flow. I had to remove and install a Watts U5B.
Would you say this review depicts the product in a flattering or unflattering light?
