If your pump does not match the depth of your water well, anticipate the pump to cycle on or off or to keep on running unnecessarily, shortening its life and adding to your electricity bills. The depth of your well determines the sort of pump you need, as there are pumps that push water to the surface in deep within the well, or ones that pull water rather. When you realize the ideal sort of pump for, a pressure cylinder or a holding tank adjacent to the pump ensures continual water delivery when needed.
Sizing the Pump
Before you can size the pump to the well, you need to know the well’s depth, its stationary water level — the measurement in the ground to the surface of the water — along with its retrieval rate. After the contractor drilled the well, he noted these details to your well license; the paperwork that he provides you should also have this info on it so that you can choose a pump that matches your well’s depth and output. Each well produces water at different rates, dependent on the underlying strata. Local health and building jurisdictions issue the well licenses and place the minimal standards for well production, which can vary from 1 to 5 gallons per minute or longer.
Shallow Well Pumps
Pumps mounted on the surface draw water from the well using a drawing activity. A pump of the kind only works with wells which are 25 feet deep or less. These types of pumps usually also want a booster or a holding tank to increase the water delivery from the plumbing lines, measured by pounds per square inch. The pump sends the water to the cylinder where it’s stored for use.
Jet pumps come in two choices, shallow well or deep well. Both pump types sit above the ground. The shallow well jet pumps draw water from one line situated in wells no deeper than the usual maximum of 25 feet deep. Deep well jet pumps utilize two lines, one for pulling the water, and you also for forcing the water into the delivery system. Deep well jet pumps can pump water from wells which vary from 25 to 110 feet deep.
Deep Well Pumps
Deep well pumps — measured by horsepower and gallons per minute delivery — install within the well from 25 to 400 feet deep. The pump is submerged deep in the well, well below the static water level, but not at the base of the well. Usually installed with a pressure cylinder beside the pump, the pump does not cycle on until the tank drops below a particular level. The pressure or holding tank sits a couple of feet from the well head. A pressure regulator installed inline after the cylinder controls the water pressure in the lines and the flow to the cylinder. It shuts off the pump when the tank is full. Three-wire pumps utilize a control unit above the ground, making them easier to mend.
