Why do I hear water running?
Because water is running! If water should not be running, it means you have a leak. Start by checking the obvious sources, dripping faucet, running toilet, looking for water on ceiling, floors and walls. If you have a water powered back-up sump pump, it may be running because of a problem with your primary pump. If you still can’t find the source of the running water is may be leaking in a wall or underground.
