Why it matters
This 1/3 HP Green Expert pump uses a water sensor and a non-return valve to drain down to about 1/25 in. In automatic mode it stops 15 seconds after the sensor goes dry.
Green Expert rates it at up to 2,000 GPH at zero lift and 22.5 GPM at 10 ft. It switches between automatic and manual, and weighs about 8.8 lb.
