Practical applications

Its 3.5 GPM flow and pressure-switch operation may be useful where demand starts and stops at a tap. Adjustable pressure helps match certain appliances when correctly configured.

What matters when comparing models

Flow and pressure figures normally describe different operating points. Work from the required delivery head, pipe length, resistance and duty cycle instead of choosing by the largest advertised number.

Check before ordering

Verify inlet filtration, duty cycle, lift, hose size and the pressure tolerated by attached plumbing. The stated flow assumes particular test conditions and falls as resistance increases.

Use and upkeep

Mount with vibration isolation, protect against dry running as instructed and flush the pump with clean water after use. Check fittings for leaks.
