What to do if my Water Ace RTS5 1/2 HP Water Pump won't shut off?

If your Water Ace Water Pump delivers water but won't shut off, several issues could be the cause. The impeller neck might be worn and needs replacement, or the pressure switch could be defective and require replacement. Try repositioning the O-ring seal. Also, the tank precharge pressure might be too high; adjust it to be 1–2 pounds less than the switch turn-on setting. It's also worth monitoring the water level during operation.
