If you can't use gravity you have to use a pump of some sort.
There are a number of problems that might cause a well not to produce water. There could be some kind of electrical problem and the pump might not be powered up. Or the motor for the pump may have failed. The pump may have lost its prime and cannot pump water (depending on the type of pump), and the water table might have become lower and the pump is now above it and dry. Think about how the pump worked before, and how it works now, and then compare the two "observations" to see if there are any differences. Does the pump sound like it comes on? Open a tap and, while listening at the tap, have someone turn on the pump. Troubleshoot this and return with a more specific question if you can.
There are many ways to drive the fuel pump. Some are electrically driven, some are mechanically driven.
Some causes for a sudden water pressure drop: 1) A big leak on the main supply line. 2) one or more faucets or shower heads opened on the same water line. 3) A utility water pump failure.
The site should have enough capacity to hold water for desired number of years. It should also have some source of water inlet.
Yes, some rare times the fins can come off the inside of the pump.
They should have a water bottle available at all times.
some times, if you just bought them you should show them were their water and food is.
It depends on your experience and a car you have. Some cars have water pump very easy replaceable. Other cars (most of them) have water pump behind the timing belt. It should take you from 2 hours up 6-7 hours.
On some engines, the water pump is mounted inside the timing belt cover, and is driven by the timing belt. Changing the water pump requires removing the timing belt cover and the timing belt. If your car is 10 years old, there is a good chance that the water pump will go out in the near future. Changing the pump while the timing belt is being changed is a wise strategy, in some cases.
On some vehicles the water pump is driven by the timing belt.
That is the weep hole for the water pump. It means the seals are bad in the pump, and it has to be replaced. Most water pumps do have a weep hole on the pump itself. If it leaks from there it usually means that the water pump seal is going bad and soon you will need to replace the waterpump. At least that has been my experience. :-( Some water pumps do have holes either on top or bottom of it. If coolant starts coming out of the hole then it's time to replace the pump.
Some times the impeller blades get bent into the housing causing noise
In some Nissan Pickups of that year, the fan clutch is actually integrated with the water pump as an assembly. Therefore, the fan clutch cannot be separated from the water pump. There are six bolts holding the water pump to the engine block; remove those bolts and the water pump/fan clutch assembly should come out as a unit.

Some people like to and some people only do it if there is a stain out of the seep hole on the pump.
I changed a Water Pump first by draining the Coolant and there are some bolts that need to be loosened to take the Water Pump off. Make sure you a Gasket on the New Water Pump and use sealant to prevent Coolant leakage.
