How To Change A Shallow Well Pump

Before you start the installation procedure, make sure y'all take everything yous need to complete information technology, bearing in mind that, while some types of pumps come with the correct piping included, with other models, yous'll need to purchase this separately.

To install a shallow well pump, y'all'll need the following components:

Jet pump
Pressure level Tank
Pump to tank fittings
Pipe clamps
Suction piping (normally 1¼")
Thread tape or piping cement for sealing the joints
Human foot or check valve

You may also need some blazon of filter and these basic tools:

Wire cutters
Wire strippers
Piping wrench

Before installing your pump, check the water in your well is clean, every bit any dirt or droppings could block the human foot valve. Also, make sure you plow off the power supply earlier proceeding.

How To Install A Shallow-Well Jet Pump

#1. Attach the foot valve making sure the spring-loaded poppet component is operating smoothly. Install the check valve vertically with the arrow pointing upwards and no deeper than 25 feet from the pump inlet. The foot valve should be suspended around 4 anxiety from the bottom of the well to preclude sediment from being drawn into the system.

#2. Using either a winch or good quondam muscle ability, lower the foot valve and attached piping into the well, joining additional pipes until you reach the desired depth. Make sure your joins are watertight, using thread tape to seal if necessary.

#3. Connect the suction piping – a make clean 1¼" pipe – to the pump. If you're installing the shallow h2o pump some distance from the well itself, utilise a 1 ½" pipe instead. Seal the threads at the suction opening and tighten securely but without over-tightening, every bit this could suspension the plumbing fixtures.

#4. Connect the outlet pipage as you did the suction pipe.

#5. Install the pump in its pump housing, making sure it is adequately ventilated and protected. Ideally, the pump should be bolted to a solid foundation, like concrete, and as close to the well equally possible to reduce friction in the suction pipe.

#6. To prime most types of jet well pumps, yous must get-go unscrew the priming cap, then make full the pump bedchamber and suction pipage with water from a hose or saucepan. If the type of pump you're using doesn't take a priming cap, utilize the h2o outlet socket instead. Once the pump chamber is full, attach the piping to the water outlet socket.

#7. Connect the pump to your pressure tank past installing the correct piping connections, not-return valve, pressure gauge, and pressure level relief valve.

#viii. Connect outlet feed from pressure tank and pump to the household supply, including a shut-off valve so that y'all tin turn the water off to the house for maintenance without losing pressure in your tank or pump system.

#ix. Consummate your pump installation past connecting the pump motor to your chosen ability supply, ensuring the voltage is the same.

#10. In one case running, bank check the system for leaks, ensuring all your pipe joints are watertight. If you detect whatsoever leakages, turn the system off and tighten the leaky connections, or patch them using pipe cement or glue.

Common Pump Types

The almost common type of pump for a shallow well is a jet pump used both in a drilled well and to access groundwater in a drive well.

Rather than existence housed within the well itself, a water jet pump is mounted above information technology, usually under some kind of pump firm or cover.

Centrifugal pumps are also sometimes used for shallow wells, although they're non every bit constructive as the jet models when it comes to suctioning water upward.

A shallow water pump uses water to create suction, driving it through a narrow pipage, creating a fractional vacuum that sucks up additional h2o from the well and discharges it into the plumbing system.

Virtually water jet pumps work together with a pressure tank. This combination reduces the pressure level on the pump organisation and lengthens the operational lifespan of the pump motor.

A tankless pump volition cycle much more than oft, coming on every time you plow on a tap. The problem with this arrangement is that a slight drip will make your pump kick in around eight,000 times a solar day, which will probably mean yous'll need a replacement within a year or ii.

How To Avoid Mutual Shallow Well Installation Problems

How Deep Is Your Well?

Knowing the depth of your well is disquisitional when it comes to choosing the right type of pump. Submersed pumps are more commonly used in deep wells of more than 25 anxiety deep, whereas jet and centrifugal pumps are more than suitable for shallow wells.

The depth of your well will as well tell yous how much pipage you need, bearing in mind that the driblet pipe of a jet well pump should hang a few feet above the bottom of the well.

What Horsepower Do I Need?

Depending on how much water you need on average per hour will dictate whether a 1/ii or 3/4 horsepower motor is required. A pump with a horsepower rating of 3/4 HP pump will produce around 950 gallons per hour (GPH), whereas one with a horsepower average of ane/ii volition only generate around 390 GPH.

Does a Shallow Well Pump Need a Bank check Valve?

While non every pump requires a cheque valve, nigh jet and centrifugal pumps are not cocky-priming and therefore demand a bank check valve to go on h2o in the pipes.

Practice You lot Have To Prime a Shallow Well Pump?

Yep, even self-priming models demand to be primed before you use them, although deep, well, submersible pumps don't. Priming removes air from the suction line and pump, which will otherwise prevent water catamenia into the pump, causing it to break down.

Conclusion

Although we've chosen to focus on installing a shallow well jet pump, centrifugal pumps are also suitable for shallow wells, if not quite as powerful. Submersible pumps are recommended for deeper wells of 25 feet deep or more than.

Regardless of the type or model of pump you opt for, it will come up with a detailed pump installation guide which will give you lot footstep-by-step instructions on how to install that specific type of pump.

While it's not a complicated process, it'southward vital that all the plumbing and electric work meets national and local regulations. If you accept whatever concerns, consult a pump professional to assist with the installation.

Ensuring the initial installation is washed correctly will extend your system's service life and save you the expense and inconvenience of expensive repairs.
