A fixed speed booster pump turns on at full speed when a pressure or flow switch calls for water and off when it stops. They cost less than variable speed pumps and are easy to service, and suit a cabin, a garden line or a house where steady pressure matters less than price. Many pair with a small pressure tank to stop the pump cycling on every tap.
