A gravity fed setup will not work since the timing for a fill is based on having a minimum of 20 psi pressure which a gravity hookup won't supply. It would be troublesome, but you could rig a water holding tank with a small water pump to accomplish this, but that setup has many complications. For instance, the water pump would need to provide adequate pressure and be on when the refrigerator's water valve opens (for approx. 3-4 seconds) to fill the ice maker with water. That means leaving the water pump running all the time (with no flow, which is not good) or somehow building a sensor switch to turn the pump off, then on, but only on to provide pressure for the few seconds each hour that is needed.
7. What Is An Electronic Flow Control (Smart Head)
It is an electronic device that controls the start and stop of an electric pump. The smart head senses when there is a drop in pressure or when water stops flowing when you open and close a tap. If there is no water in the system the smart head also senses this and would not let the pump run dry, thus protecting the motor. For this reason a float switch is not required.
the pump is controlled by the storage tanks pressure switch , if it continues to run well after the pressure tank has refilled with water , either the switches manual override has been activated (lever) or its defective or blocked off with mud
You could have two problems. The first and most likely is that the pressure tank does not have a high enough pre-charge or the diaphragm has a leak. The pressure tank acts like a shock absorber for the well pump and pressure switch. When the water pressure drops the switch turns the well pump on. The pump runs until the pressure switch stops the pump. As the water pressure builds it pushes up on the diaphragm inside the pressure tank. If the pre-charge pressure is too low the system cycles less but the pressure fluctuates more. To fix this, the tank will have a valve on top that looks like a tire air valve. The tank pre-charge should be 30-35 psi. If your pressure switch is working properly, when the pump builds up the pressure about 15-20 psi more, the switch shuts the pump off. The pre-charge above the diaphragm pushes down and forces the water out to the tap.
If the pressure switch is set incorrectly the fluctuation may produce similar results. The pressure switch should be set to deliver adequate pressure and according to the well pumps working limits. Depending on the how far up the water has to be elevated to reach the highest shower head the more pressure is needed. The pressure switch has electrical contacts that could be burned and not releasing to stop the pump correctly. This should be checked by qualified service technician. Electricity and water don't play well together, add in a little carless good intent and you could have worse problems.
Get out the pressure gage and check the pre-charge, add air with a bike pump or a regulated compressor. If water spurts out of the air valve, the diaphragm has a leak. If the pressure is not the problem, call for service. This video has all the info you may need. Components Of Typical Well Water System
If in the past your system can build-up pressure up to 40 psi even if the supply valve is open and water is being used in your house, then your pump impeller maybe already worn out that's why its pumping capacity was reduced.
blocked pick-up screen could cause the pump to overheat, old pump could be simply overheating, mineral build up in pipes could be causing over pressure at the pump creating overheating....
Three things to check 1. There may be getting sediment in the water line to switch. Flush the well tank at the boiler drain to see how much sediment (if any) comes out. Flush well if heavy sediment and call Well company. 2. Make sure the check valve is OK also. 3. If the impeller is bad on the pump it will not build pressure and keep running. 4. The well may be going bad, low volume. Call well company. RJ
SOUNDS LIKE YOU HAVE A LEAK DOWNSTREAM PROBABLY UNDERGROUND. THE PUMP HAS NO REASON TO COME ON EXCEPT TO BUILD THE PRESSURE BACK UP. HOPEFULLY YOU HAVE A GAUGE IN THE DISCHARGE LINE YOU CAN WATCH IT DROP AFTER THE SYSTEM SHUTS OFF. HOPE THIS HELPS, JODY
