Abstract: A water-pressure alarm device can include an inlet that receives water. It can also include a tube in fluid communication with the inlet that reacts based on the pressure of the water within the tube, a link mechanically coupled to the tube, and a movement mechanically coupled to the link. A conductive needle can be mechanically coupled to the movement, such that a reaction by the tube causes the link, movement, and needle to move accordingly. A first electrode is associated with the needle and a second electrode is mounted in a location that acts as a stop for the needle. The first and second electrodes are connected to an alarm that operates when the needle contacts the second electrode. The location of the second electrode can be chosen to correspond to a particular pressure level that would warrant an alarm, such as 100 psi.
