We had a PRV (Wilkins NR3XL) installed a while back to help with high supply pressure (90 to 100 psi at night). It always seemed like the flow from some of the faucets would drop off rather dramatically shortly after the water was turned on. Last weekend I finally got around to putting a gauge on an outside faucet that is about 5 feet of pipe beyond the PRV. The gauge showed around 60 psi as the setpoint. But, as soon as I turned on a sink faucet, it dropped down to 40 to 45 psi. Is this typical for a PRV? The flow curves for this model on the Wilkins website would suggest it should be more like 5 psi (??).
