For the first time I'm having issues with an older pump. Currently the
pump is short cycling.. Here are the specs.

1/3 hp pump down about 180 feet (Pump is original at 30 years old)
Well recharge rate it about 1gpm
WellxTrol 20gal tank
Pressure Switch is set to 44-64psi

The pump kicks on at 44psi, runs for a 1 second, then turns off for
45-60 seconds
It takes 15-20 to bring the tank up to 64psi, running 1 sec on 45 off
the entire time.

I checked the tank pressure when it was empty and it was at 25psi.. I
charged to 38 and refilled -- still short cycled, I charged to 42psi
(manufacturers recomendation of 2psi below cutin) and it still short
cycled.

I don;t think the well is dry as the short cycling was observed last
evening and this morning (12 hours of recharge on the well).

Any thoughts??


And the winner is!!!

Pump is shot, Tank is shot.

After 30 years of scale, sediment, and hard livin' the arteries of the
tank got clogged. There are three areas of concern to the tank
reducer 1 inch from tank to 3/4 for house, the 90 degree turn at the
bottom of the tank, and the dispurser just inside the pressure tank
(deflects the water so it doesn't blast into the bottom of the air
bladder). These had reduced down to about 1/4 inch due to scale. When
the pump turned on, there was suffecient resistance that caused the
pump to stop. After the reset it attempted again.. Each time there was
enough water getting through to raise the PSI a pound or so.
Eventually after 30 min or so the tank would come to full pressure.

After shortcycling so much over 36 hours, the pump finally kicked the
bucket. The controller would still call for water every minute or so,
but it took 8 hours of trying to get the tank filled.

When we pulled the pump the inlet screen was 75% plugged. After 32.5
years it was time to send it to the big well in the sky...

Thanks for all your input!
