SOLUTION
1. Long wait times for hot water?
Troubleshooting Pump related issues
Pump does not have power
Check the power supply to the pump as well as the timer settings.
If there was a power outage, the timer does not reset and will require you to manually
reset the timer.
Pump direction flow
Check to ensure the pumps directional flow is correct.
Water supply angle stops
Verify the water supply angle stops are on and connected correctly to the Sensor valve.
Long Water Piping Network
Install a second Sensor Valve near or parallel the first one. (See Page 4)
2. Long wait times for hot water?
Troubleshooting Timer related issues
Timer Settings
Check to make sure the Timer Ring is set to the current time of day.
Manual Switch Setting Make sure the
Manual Switch is not set to the "OFF" position
Programming Tabs
Make sure there are not too many Programming Tabs pushed towards the center of
the timer ring. This will indicated the timer is turned off.
AM/PM Settings
The timer is on a 24-Hour clock. Make sure the Timer is set for the correct 12 hour
period "AM/PM"
3. Long wait times for hot water?
Troubleshooting Bypass related issues
Hot water does not reach a temperature above
96°F (36°C)
Check the insulation on your hot water supply for damage.
If insulation is undamaged and sufficient, increasing the temperature of your heater/
boiler may be required.
Not enough time may have passed for the
system to stabilize
This depends on a few different factors.
1. Piping Network Size
2. Hot water Tank
3. Water Usage
You can set your Hot Water Recirculating Pump to start 15 to 30 minutes earlier to
compensate if necessary. The length of time will depend on the length of time you
are having to wait.
Bypass Valve has failed
Follow these instructions to test the operation of your By-Pass Valve.
1. Verify that the pump is operational.
2. Check the Timer Switch and settings.
3. Go to the sink where the Sensor Valve is installed. Close the cold water
supply Angle Stop.
4. Open the cold water faucet.
5. Wait for the water to slow down to a drip or no flow.
This will take approximately 1 minute.
6. If water does not slow to a drip or completely off, carefully check the
temperature of the water. The temperature should be around around
90°F (32°C) ± 4°
7. If the water temperature is more than 100°F, replace the valve.
No water flow
Verify the Sensor Valve is installed correctly. (See Page 4) The sensor valve can
be installed vertically or horizontally, however, it must be installed facing the
correct direction.
Hot water on one end of the hose but not
the other
Verify that the sensor valve is installed at the faucet with the greatest piping distance
from the hot water heater. Uninstall the sensor valve and reinstall at the sink that is
taking longer than normal. If this does not resolve the issue, you may also have a
branched line in your home which will require a second valve to be installed on the
other end of the home.
Uninsulated piping or long runs of piping on
concrete foundation.
You may require adding an additional valve or installing valves in parallel to increase
the flow rate and reduce temperature drop. (See Page 4)
