Ritchie Pressure Reducing Valve Package, PR75-3/8, 1/2 in. Valve Series
Ritchie Pressure Reducing Valve Package, PR75-3/8, 1/2 in. Valve Series
Part Number PR7538
Couldn't load pickup availability
Fits into the supply line ahead of a Ritchie waterer and holds the pressure steady before it ever reaches the valve. Built for the 1/2 in. valve series waterers, with the fittings for 3/8 in. hose included so the line can simply be spliced.
Why a third new valve drips like the first two
Ritchie bands its valves by pressure and marks them by color. The green valve is the top band: on the 1/2 in. series it is 13597, good for 60 to 80 PSI. Put any valve behind pressure above its band and it has more force on the seat than it can close against. Ritchie's own words are that a constantly dripping valve is the first indicator of high pressure, and that the valve rubber comes out distorted rather than flat. Fit a new valve into the same line and the same thing happens again.
Read the gauge at the waterer
Ritchie says to test at the unit rather than back at the source, because the two figures are often not the same. Municipal water sits in the high band by their reckoning and shifts through the day as other people draw on it. A well with the tank cut-out set high can land in the same place.
What is in the package

One honest caveat: pressure is not the only reason a valve weeps. Ritchie points at grit and mineral scale on the rubber as the usual culprit on well water, so look the rubber over for buildup before spending on a regulator. If you are unsure, send your model number through our contact form.
