Likewise, does a shallow well need a check valve?
Because shallow-well jet pumps use water to draw water, they generally need to be primed–filled with water–before they'll work. To keep water in the pump and plumbing system from flowing back down into the well, a 1-way check valve is installed in the feed line to the pump.
Beside above, why do you need a strainer for a foot valve? Most foot valves usually come fitted with an inlet strainer. This strainer filters the incoming water, thereby preventing debris in the well water from entering into the pipe and clogging the valve, jamming it in the open position. Pumping water from a lower level to a higher level requires a lot of energy.
Correspondingly, what happens when a foot valve goes bad?
A leaky foot-valve or check valve allows water to drain slowly down the well piping and flow back into the well. It can drastically increase your electric bill and occurs when no water is being drawn from the system. Unfortunately, a leaky foot-valve or check-valve is not the only cause of intermittent cycling.
Do I need a check valve and a foot 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. If an additional check valve is required, it should be placed after the pressure tank to allow the pump and discharge pipe to remain pressurized.
