A protection system for hydraulic systems, mainly for pipes, faucets, valves, boilers, furnaces, etc. which consists of a handling panel, a cut-off valve, a fluid leak detector, at least one pressure sensor, and a water shock absorber, and such a protection system can detects leaks or floods and will shut off the water pressure to the structure, and this protection system can be programmed to reduce the pressure in the system in order to maintain a state of low pressure in order to reduce the toll on valves, faucets, furnaces and pipes, etc as long as the user does not need to use the water or to open such valves, and this protection system will increase the pressure when it is needed, and this increase in pressure can be programmed by the user through the use of the "override" maneuver from any valve or faucet, and it will detect if the pressure needs to be increased to serve the needs of the water heating system if the cut-off valve shuts off the water supply to the structure, thereby preventing damage to the structure, and the protection system will let water flow within the system via the valves in order to prevent water freezing within the structure in very cold temperatures, thereby also preventing damage to the structure.

[ I claim:] [1.] A fluid drip detector which is integrated with a fluid cut-off valve in a sensing device assembly comprising:a valve housing having a first bore in one end and a second bore at the other end, and at the end of the second bore is disposed a seat;a valve membrane means in selective co

[ I claim:] [1.] A fluid drip detector which is integrated with a fluid cut-off valve in a sensing device assembly comprising:a valve housing having a first bore in one end and a second bore at the other end, and at the end of the second bore is disposed a seat;a valve membrane means in selective contact with said seat and allowing a variable close location relative to said seat, the valve membrane means surface being exposed to fluid pressure such that when fluid pressure drops at the second bores the fluid pressure at the first end urges the membrane means to move from the seat in a detectable membrane movement that signifies a fluid drip status or fluid movement condition, such membrane means movement also allowing fluid flow from the first end to the second end; anda housing cover situated on said membrane/valve in order to define three chambers, a first chamber at the first bore, a second chamber at the second bore and a third chamber at with selective fluid communication to each or both of said bores, whereby whenever said membrane is positioned away from said seat there is an open flow of fluid between the first and second bores thus defining a fluid flow condition for this first position, and if said membrane/valve means is positioned to engage said seat, this alternate position of said membrane/valve means is defined to yield a no flow fluid condition; andan electrical switching means integrated to said valve/membrane means, whereby said membrane movement changes the electrical status of said electrical switch.
