We have sand point well with a Craftsman Shallow Well Jet Pump 1/2 HP, 40/60 Pressure. We bought the house almost 30 years ago and have replaced the pump and the tank sometime in the past but it has been at least 10 years. We have recently experienced a dramatic loss in water pressure. For example when the toilet is flushed we have no or very little water running from a faucet for a period of time. I watched the pressure gauge and it was at 36 psi for 4 minutes before increasing above 40 psi, then less than 1 minute for it to move from 40 to 70 PSI before the pump shuts off.
The pump kicks on every time we use any water. It seems as if the water flow is greatly reduced. It can take 20 minutes to fill the tub for our clothes washer and the shower will have a decent flow for about a minute then there is only a very weak flow from the showerhead.
Any suggestions? What other inforamation would be helpful? Thanks!
