(1 day after installing new white sediment filter)
After being out-of-town for a month, the well pump protection circuit kept tripping due to high load. After testing, the well pump resistance is normal, but the running pump's amperage varies 7--20A (after bypassing protection circuit).
Also, the sediment filter now quickly fills with dirt, and quickly turns brown (see image).
Pump contractor says 15 y.o. pump is failing mechanically, $4,000 for new pump/install (~700 feet, constant-speed pump). Says silt is likely because low pressure stirred up sediment in tank/line.
However, wouldn't new dirt/silt indicate well lining failure, and that the pump may be fine but is now using more power to pump up the silt?
I wouldn't want to pay $4K and then have to re-install a new pump after getting the well lining fixed ($10K+!!). How should I proceed to get this diagnosed and fixed efficiently/correctly?
