Locate a section of pipe that is near the valve and has at least five inches of straight, continuous, uninterrupted pipe. Installing on a pipe other than the main line will not allow you to see total water usage in your home. Install the Monitor on the main water line, before any branches to other appliances. The Monitor is compatible with 3/4" and 1.0" pipes made of Copper-M, Copper-L, CPVC, or PEX. It is the line that splits into the hot water heater and the cold water for the building. The main water entry line is typically near the water heater. The main water entry line should have a shutoff valve used to stop the water supply to the home.

The main water entry line may be located in a basement, utility closet, garage, or crawlspace based on which type of dwelling it is (a house, townhome or apartment).
