Garratt from The Pool Boys came out to add an in-line chlorine dispenser and check the hot tub which was turning on and off randomly. He was very professional and courteous. He had the dispenser installed in less than 30 minutes and found out what was wrong with the Hot tub in less than 15 minutes. He got the part quickly and came back the next day to install. All is working great and at a reasonable cost. Very pleased!
