In good conditions, the maximum depth to draw water in a shallow well application is 25′. The use of well points in a shallow well is generally not a good source for potable water. Shallow wells are more exposed to pollution from fertilizer, animal waste and dry wells.
Does a shallow well need a foot valve?
Foot valves are used in shallow well jet pump and deep well jet pump installations. The foot valve is required to be installed at the bottom of the well suction line piping. If you notice that a shallow well no longer has any water, one of the first things to check would be if the foot valve needs to be replaced.

What size pump do I need for a shallow well?
2½” – Jet pumps in shallow well applications (depth less than 25 feet) should be installed using 1¼” suction piping with a foot valve. 4″ – Convertible jet pumps used in deep well applications (depth greater than 25 feet) and deep well submersible pumps.
Which is better foot valve or check valve?
We recommend using only one check valve or foot valve in a pump system. A foot valve should be at the inlet to the suction line of turbine, centrifugal, and jet pumps. The check valve slamming shut from a full open position when the pump is cycling repeatedly is the main cause of check valve failure.
Does a check valve go before or after a pump?
The most common installation is at the pump. A check valve may be installed on the suction side of the pump to maintain the pump’s prime in the event of a pump shutdown. A check valve will be used commonly on the discharge of the pump to prevent backflow from the downstream system, when the pump shuts off.

How much water is in a shallow well?
The typical 6-inch diameter well will hold approximately 1.5 gallons of water per foot of casing. The height of the water above the pump when it is not operating, multiplied by the gallons of water per foot of casing approximates the amount of available storage within the well casing.
Do well points have check valves?
Usually a driven point well does not incorporate a foot valve. Rather, since such wells are by definition always shallow, there will be a check valve at or on the pump.
How far below ground is the water table?
Groundwater may be near the Earth’s surface or as deep as 30,000 feet, according to the U.S. Geological Survey (USGS).

Does a shallow well pump need a pressure tank?
Pumps will work without a pressure tank, as there are automatic pumps fitted with a constant pressure controller so these pumps start and start on demand. We recommend having a pressure tank particularly when you have a shower or a toilet where the pump is rarely operating at 100%.
How far can a 1 hp pump push water?
A 1 HP sump pump has significant vertical and horizontal reach, making it ideal not only for residential homes but also for commercial units. These pumps deliver an average of 19 GPH and can lift water from wells that are 200 feet deep.
Can you use a submersible pump on a shallow well?
Submersible pumps are selected based on the flow and pressure required and can be installed in shallow wells of just a few feet deep or in wells over a thousand feet deep!Apr 19, 2021.
Where do you put a check valve on a shallow well?
The check valve should be installed in the suction side piping as close to the source of water as possible. It should not be installed within 2′ of the pump’s inlet, or anywhere on the discharge side of the pump. A foot valve functions just like a check valve plus has a strainer on it.
What is a globe valve?
A globe valve regulates flow in a pipeline. It is used to control or stop the flow of liquid or gas through a pipe. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
How far should valve be from bottom of well?
To prevent sand and sediment from entering pumping system, foot valve/strainer should be at least 5 ft. (1.5 m) above bottom of well.
