......shallow well water-pump problems with pressure switches that turn on at 30-psi and turn off at 50-psi...you gotta be a water-pump detective to diagnose the correct issue...which can be very challenging...a neighbor once took about three days trying to find the problem and actually dug up the buried 1 1/4" diam poly-vinyl-butyl black tubing that snaked down into the lake, thinking that it had froze up and cracked somehow over the winter months.....which was not the case....only to find out that a chipmunk had been using the inside of the black poly-vinyl-butyl 125' x 1 1/4"diam long tube as a storage place for acorns....and that had plugged it up.....how's about that! .....
....prices for water-pumps and accessories can vary by quite a bit from store to store.....I know that an almost easy-to-install, tether on-off switch, for a septic waste-water pump cost about 20-dollars at a local big box store, while a similar item went for almost 50-dollars at a nearby local hardware store, so it can pay to shop it around ... or just go directly to Lowe's ... which has a very liberal, 3-month return policy, except when that older thin woman with the white hair is at the returns counter ....
