CAUSE
Timer's Manual Switch
Programming Tabs
Bypass Valve has failed
Incorrect Sensor Valve Installation
Water temperature from water
heater/boiler
O-Ring failure inside the pump
SOLUTION
Timer Manual Switch is set to "ON" which will cause it to run 24/7
Adjust the Programming tabs for the desired run times
Make sure there are not too many Programming Tabs pushed
towards the "ON" position This will cause the pump to run more
often To best address this reduce the number of Programming
Tabs in the On position Modulating the Pump On and Off may
help (ie 30 minutes before the first shower until 15 minutes after
last shower)
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
90°F (32°C) ± 4°
7 If the water temperature is more than 100°F, replace the valve
(See page 4)
If the water is not hot enough it will not shut off the By-Pass to the
cold water line Increase the temperature in your hot water tank/
boiler
The connections use a standard ¾" hose gasket and should be
periodically replaced We also recommend using new flex lines as
gaskets are usually supplied with them Keep in mind there may
be a need for Dielectric unions when using dissimilar metals as this
can lead to premature corrosion if not properly installed
