Enero Water Leak Detector is installed on the main incoming water line. It should be fitted upstream from where the water system begins to branch off to other appliances and downstream from pressure regulators and water meters. It is also important to mount the valve so that the property owner has ready access to the face of it to be able to access the manual shut-off valve and reset the device as necessary. Additionally, the valve should be fitted into a location on the main line so that it does not interfere with flow to fire suppression and irrigation systems.
