The Shurflo by Pentair King II Premium 4.0 24VDC 4.0GPM 55PSI Fresh Water Pressure Pump 4148-163-E75 is the ideal choice for medium-to-large vessels that require a reliable, high-volume water system. While standard pumps often require an accumulator tank to prevent "pulsing" at the faucet, the Shurflo King II's internal bypass manages the pressure internally. This saves valuable space and simplifies your plumbing.
For the quietest possible operation, use at least 18 inches of flexible high-pressure hose on both the inlet and outlet ports before connecting to rigid plumbing. This prevents the pump's natural vibration from being transmitted through the pipes. Always mount the pump on a solid surface and ensure the included strainer is installed on the inlet side to protect the valves from debris.
