ABSTRACT:
A water level monitor and alarm indicates when the drain valve in a toilet flush tank is improperly seated and water is not filling the flush tank as required. The monitor can also be adjusted to indicate when water is overfilling the flush tank. A hollow tube contains a float and fills with water as the tank fills, lifting the float. If water continues filling the tank after a predetermined level is reached, a portion of the float will trip a switch and indicating devices outside the tank will signal the overfill. When the flush tank empties, water is metered from the hollow tube through a variable size opening and gradually lowers the float contained therein, causing the float to descend at a slower rate than the tank water level. If the tank does not begin filling with water at a proper time to intercept the float, the float will continue to descend, and, at a predetermined level, trigger an alarm to signal that the flush tank is not filling.
