I replaced my old, leaking "WaterMate" regulator with this new, lead-free Valterra -- and it works great !! The Orange plastic grip allows easy, screw-on installation and removal. It comes complete with an internal screen/washer, too. NOTE: The included screen/washer is NOT stainless steel, so it WILL rust through in a couple of months -- I use ONLY stainless-steel screen/washers to avoid bits of rotted screens from clogging the Regulator, the Timer, or the Sprinklers. The lead-free "brass" regulator body is designed primarily for RV hookups -- to keep dangerous LEAD from leaching into your drinking water, but mine is mounted on the garden hose faucet to prevent blow-outs of soaker hoses and drip systems. Another feature of the Valterra shows up in the monthly Water Bill -- it's MUCH lower than before the installation of the Valterra regulator !!
The Valterra Regulator runs at 52-55 psi., tested at the faucet with a Rainbird P-2 Pressure Gauge. I use the Valterra regulator ahead of an Orbit Digital Timer for precise lawn watering and accurate water distribution through GILMOR Gear-Drive Sprinklers, also available at Amazon. My order arrived promptly and in perfect condition. Thanks, Amazon !! UPDATE: 14 June, '14 -- Regulator is still working perfectly -- with no leaks and/or drips -- and the Water Bills are still lower than before the Valterra was installed.
