My water HOLDING TANK for my WELL was overflowing. I thought I had a bad FLOAT. They replaced it UNDER WARRENTY. It still was overflowing. They replaced a CONTACT in PUMP SAVER box. It still overflowed. After 2 hrs they determined it was bad wire from holding tank TO pump saver box. They only charged me a TRIP CHARGE $140 for the whole appt, since they don't pull 150 feet of wire. I need an electrician. They let me keep the new parts!!! They were SO nice too! I will use them again.
