Ok so I live in central Texas. I have a 900 foot well, pump is sitting at 600 feet, if I remember the report correctly. I have a pump saver in front of the pump control box. The well pumps into a 1000 gallon cistern, then there is a boost pump that pressurizes for the house. 9 months out of the year everything works fine, but when the ambient temperature reaches high 90's and into 100's, the thermal overload on the control box resets before the float switch in the cistern opens (after 5-10 minutes). I can only relate this to the ambient temperature, because in the mornings and evenings I can reset the overload and the thing will run for 30 minutes straight while it fills up the cistern and shut off like it's supposed to. But only when it's hot outside does the thermal overload trip; and I also do not have any trouble throughout the rest of the year. I guess my question is a) is this normal b) can I do anything to change it and c) am I hurting anything by just resetting the overload when it trips. This happened last year and I just kind of brushed off the problem as not a big deal, but this is year 2 of this.
