Pros & Cons of Different Water Well Equipment
Submersible Pump
- More gallons per minute and pressure
- More efficient with electric power
- No priming pump is already in the water
- More reliable
- Not well suited in a shallow well
- Could pump more water than the well produces
- Does not withstand abrasion from sand
- Will over heat in a run dry condition
Jet Pump
- Prefect for shallow wells
- Efficient in power and delivery in shallow wells
- Shallow wells are usually 25’ or less
- Not efficient over 25’ using the deep well jet
- Does not produce much water and uses more electricity because it requires a bigger motor to pull the water up.
- Jet pump requires priming if the pressure goes down or runs out of water
- Not very reliable
Bladder or diaphragm type pressure tanks
- Continuous pressure
- Uses all the water every cycle
- Annual maintenance
- If the tank fails and fills with water it becomes trapped and makes the tank impossible to drain and very heavy to remove
Air to Water Galvanized Pressure Tank
- Cheaper in price for initial purchase
- Works well with iron removal system
- Becomes water logged any time the air charge is not sufficient
- Not what would be recommended
Constant Pressure System
- Constant pressure
- Fits in a small space no huge pressure tank required
- Uses a 3 phase motor with single phase power which allows variable speed so the pump only produces what is being called for
- Best performer for irrigation or fire sprinklers
- Pump runs even to draw a glass of water
- New technology
