We sleep one floor above our well pressure tank. Last night my wife
awakens me from sleep to inform me that the well pump keeps coming on.
I spring to life, get down to the basement and start troubleshooting.
This is what I found:
With the valve after the well tank turned off, house gets no water, I
watch the pressure gauge and sure enough it goes down, about 20 psi in
two minutes. Pump kicks in, tank reaches cut off pressure and again
pressure goes down. So I shut off the electric to the pump and go and
Google well pumps and check valves.
I go back and run the pump and watch the gauge, sometimes the pressure
does not drop, the pressure holds!
What we have:
Pump down at about 180 feet, water at about 60 feet down, 1/2
horsepower pump, 220 volts, 82 gal Flotec bladder type well tank,
check valve at well tank, not sure if there is check valve at bottom
of well, well pump at least 10 years old, Home Depot well tank check
valve 7 years old.
My thoughts: check valve sometimes works and some times does not %^),
does that happen? Did I leave out important clues?
Is there a way to know, or can I do some test to determine if I have a
check valve in the bottom of the well? If I do does this mean that one
check valve is bad and one check valve sometimes is bad?
Cheap fix, replace check valve at well tank? Is cheap fix a bad idea
or does it buy me time?
Thank you for any help.
