Why does my Watts Water Pump have long wait times for hot water?

  There could be several reasons for long wait times. It could be due to the pump not having power, so check the power supply and timer settings. If there was a power outage, you may need to manually reset the timer. Also, ensure the pump's directional flow is correct and that the water supply angle stops are on and correctly connected to the sensor valve. If you have a long water piping network, consider installing a second sensor valve near or parallel to the first one.

  If you're experiencing long wait times for hot water, there are a few timer-related issues to check. First, ensure the timer ring is set to the current time of day. Also, confirm that the manual switch is not set to the "OFF" position. Make sure there are not too many programming tabs pushed towards the center of the timer ring, as this indicates the timer is turned off. Finally, the timer operates on a 24-hour clock, so verify that it's set for the correct 12-hour period, either AM or PM.
