what is the flow rate (gpm) with the flow regulator removed?
The flow rate is set by federal law.
You go messing around with that regulator and you can find yourself deported so fast your head will spin!
Does this deal come with the hose and mount?
Yep:
Angle-Adjustable Overhead Bracket allows for hands-free use
Solid Brass Metal Fittings & Hose Nuts will not leak, crack or strip
Heavy-duty Stainless Steel Hose with extra-thick pressure-reinforced inner tubing for more durability
I love it, no tools required, not even a wrench, just hand tighten everything
