"My 25 year old pump was going out when I called at 4:30 pm. By 5:30 pm Prairie State Water Systems was at my house to inspect my system and verified that my pump was going out. At 8 am the next day, two men arrived. My pump was replaced with higher grade piping, couplers, and new wiring. As my system was 25 years old, I wanted the control box, pressure switch, and pressure tank in the basement replaced. By lunch I had a new system done at a fair price with a very high level of craftsmanship. I highly recommend Prairie State Water Systems."
