I ran across a big accumulator for an RO system in a thrift store cheap and connected it into our water system. It stores about a gallon of water so the pump doesn't need cycle nearly as often. I was lucky to buy a variable speed pump from a tailgater at Quartzsite years ago and love it! Instead of running full tilt or not, it slows down gradually before stopping as the accumulator tank fills. I have to listen closely to hear our pump run. The variable speed pumps are more that twice as much as the standard pumps (unless you find a tailgater selling new ones).
