      Water detectors from Grainger detect water leaks before they cause costly property damage or let mold grow. Simple water leaks from water heaters, sink drains, broken washing machine hoses (the number one cause of residential water damage), clogged air conditioner drain tubes and leaky or broken pipes are immediately detected, resulting in quick corrective measures. Water detectors dramatically lower damage, clean-up time and money.
