I tightened the allen bolts and it did make a difference. The wife concedes it's quieter but still audible from 100 feet. The box still is making noise from vibration, I'm waiting for the hardware store to get in some rubber washers to use against the telephone/light pole the Vertex enclosure is bolted to the pole. While the enclosure is off I'll check and tighten all the bolts where the pump is attached. Any suggestions where to check next?
