Definitely start with a backflow preventer valve on all the lines that go to outdoor places (hose bibs, sprinkler systems, the washing machine etc) this should be installed basically before the line exits the house area, so its easy to maintain, and so the backpressure is generally greater keeping the valve closed.

Another thing you could try is to place a pressure tank near your house, so the pressure in the lines stays relatively constant
