Ao smith 1 horse house water pump. water pump only fills tank half way to 3 /4 . pump does not stop running.. water pump leaking a little water out of water valve spiot
Hi, W/D here.
The tank has to have an air cushion in it for the water to be delivered as water is not compressible. Ideally, the water is expelled from the tank without air leaving the tank, and then the pump starting to refill the tank. The air in the tank is supplied either by an air bladder installed in the tank, or by an air injection system where a little air is injected into the tank every time the pump runs and shuts off.
A little leak at the pump is not a big deal, but should be capped off or the faucet repaired/replaced at your earliest convenience. Ideally, the water level in the tank should be closer to 80%; so if you have an air injection system, you might let a little air out of the tank (if you have a top valve), and this might cure your cycling problem. With the tank level as is, you are probably getting some air in your lines into the house. If you have an air bladder in the tank, the required pressure of the bladder, with no water in the tank should be on a sticker located at the schrader valve on the top of the tank (A schrader valve is similar to the air inlet valve on a bicycle tire). The ones I am familiar with are set around 28-29 psi. If you have an air injection system, it may need to be replaced. If the costs are close, I would elect to go with a bladder tank, as I've found that they eliminate many of the problems associated with the air injection type.
Fix or cap the faucet so you have no leaks showing at the pump or tank. Catch the pump running, and wait for it to shut off. When it does, close the discharge valve to the house and wait. You may need to trip the breaker for the pump. Watch the pressure gauge. If the pressure falls, the problem is with the well, and you may need to pull the inside well supply line from the casing and make repairs at the foot. My experience has been that it is better to replace the leathers, jet valve and foot valve all at once than to hope they hold if I repaired only one part.
If the gauge holds after 10 minutes, open the valve. If the pressure falls, the problem is on the house side of the valve.
Resolve any issues on the well before checking further, as that's where most well problems originate.
Adjust your tank level and pressure. If the pump continues to cycle, you may need to replace your pressure switch.
