Pumping from a Lake: Well Usage, Pump Sizing, and Pipe Selection

Three questions: 1) Is frequent well use beneficial? 2) What pump for 75 ft rise + 600 ft run from a lake? 3) What supply line size for 1/2" hose, considering pressure and volume?

Well Usage

"Somewhat true. If your well is in good condition and in good water, you won't 'hurt' it by using it. If a well sits for long periods with no use, the screen can get a bit plugged. That depends on water quality."

Lake Pump Requirements

• Pressure: Need 75+ PSI at pump (32 PSI lost just lifting 75 ft).
• Pump type: 2 or 3-stage, 1.5–2 HP.
• Pipe size: 1" minimum, but 1.25" or larger recommended for 600 ft run to minimize friction loss.

Pump Selection Advice

Matt emphasizes buying a pump with local support: "Each area of the US have different pump manufacturers which are predominant. You don't want a pump which is hard to find or difficult to get parts or service. If you have neighbors with sprinkler systems, ask what kind of pump they have."
