I'd appreciate some help diagnosing our water problem. About three days ago my wife drained and tried to refill the hot tub. The hose started to spurt air mixed with the intermittent water. I shut off the presure pump at the square gray control box as it was running continuously and waited a few hours. I then opened the hot and cold water facets thoughout the house and turned the pump back on before closing the faucets in an effort to purge the air from the pipes so that the pressure switch would get above 40 psi and stay on. Meanwhile I looked at the guage at the bottom of the bladder (well-xtol) tank which stays at just under 40PSI and seems to have the submersible pump shutting on and off ok. Today, (two days later than the hot tub episode), I can get the pump in the basement to stay on with the pressure hovering around 45-50 psi but the water facets continue to spurt air without actually purging (even after several minutes) and when all faucets are closed the air continues to keep the pressure around 45-50 psi. Finally, the water shows sign of sediment and a light brownish color. I can't tell much from opening the well. It is a cement frame about four foot square and when I remove the metal cover it just shows a pit about three feet deep with a single pipe coming from the house and headed vertically underground. Do you think it is a well running dry issue or the early signs of a submersible pump going bad ? We haven't had an unusually dry summer, in fact we had two or three days of steady rain less than a week ago. Furthermore, this is the first time in the seven years we've lived in the house that we've had any of these symptomsIncluding filling the hot tub numerous times) Your thoughts would be greatly appreciated.
