The tank and pressure monitor can be set up in any configuration imaginable. 

It may be installed to monitor some or all of the following:

Pressure of the water line feeding the tank (if not needed do not install the pressure switch)

Overflow of the tank (float valve not working properly)

Low tank level (float valve not opening or no water being delivered to the tank)

In a standard application a low pressure switch is installed in the water line that feeds the tank. To install the pressure switch drill a hole in the pipe (drill bit and 1/8" pipe tap is included) and tap threads into the pipe. Screw on low pressure switch (DO NOT BOTTOM OUT THE FITTING, only screw in 7/8 of the way). Use provided super glue on threads (this is used instead of pipe thread compound and will work on all types of pipe).
