3: What is well development?
A process that ensures that the well’s sand filter has been improved so the well produces clean, sand-free water
4: What is the most effective way to stay updated on your pump’s condition?
Manual inspection

5: What could be the consequences of using an undersized pump in a well?
The pump will give too high pressure
You can find the answer here >
5: What could be the consequences of using an undersized pump in a well?
The risk of cavitation is very high
You can find the answer here >
5: What could be the consequences of using an undersized pump in a well?
The pump may not be able to deliver the required capacity
6: Why is it a good idea to make a well where the groundwater level is as high as possible?
The shorter the distance is to the water the less expensive it is to make the borehole and subsequently to pump the water to the surface
6: Why is it a good idea to make a well where the groundwater level is as high as possible?
The shorter the distance is from the surface to the ground water, the better the water quality is

6: Why is it a good idea to make a well where the groundwater level is as high as possible?
A higher level means lower water temperatures and better motor cooling

7: What can be done to the well if sand continues to enter a well after the well development has been carried out?
The well driller can try to run the pump at its maximum capacity in short periods of time over a couple of days
7: What can be done to the well if sand continues to enter a well after the well development has been carried out?
The well driller can replace the casing with a new one with smaller slots
