My deep well pump (100 feet) does not activate automatically. Instead, I have to pour 2-3 gallons of water to activate it. The pressure is about 30. After a while, it will stop altogether and I have to call the plumber who says the foot valve and/or the rubber gasket is/are broken. He and his crew would pull out the length of the pipes replace the broken parts and the pump will do well. After a while, it will lose pressure and I have to go back to pouring water until it stops working. This cycle has happened 3x in the past 4 years and I am tired of paying the plumber and buying parts for replacement. Right now I am again pouring water to activate it. Sooner or later it will stop. What do you suggest??
Hmmm. Pour water to activate it sounds like a Jet pump. Replace it with a submersible pump (Two-wire is more reliable than 3-wire in the modern era, I think - not to mention the wire costs less and on the comparable models I was comparing could also be one size smaller.)
Jet pumps are a holdover from a bygone era when electric motors were much less reliable, and are both troublesome and shockingly inefficient (power in compared to water out) .vs. a deep well submersible pump.
