A leak in the supply pipe.
A drop in brake fluid pressure (caused by, say a leak or crack)
A leak probably wouldn't cause a "sudden" drop in pressure. It sounds more like the system has more users than it can supply and pressure drops when someone else turns on their shower or flushes their toilet.

vacum leak !!!!!!!!!!!!!!!!!!!
The purpose of a leak detection pump pressure switch is to immediately alter the system to pressure drop. These are most commonly associated with seal or valve failure.
Leak in the hydraulic system pressure drop is caused. Pressure drop measured by a manometer. There is oil leaking hydraulic oil, along with signs of connections.
The point pressure leak test is a method used to check for leaks in a specific location of a system or device. It involves pressurizing the area and monitoring for any drop in pressure over time, which can indicate a leak. This test helps identify and locate the source of leaks quickly and effectively.
With no air in the system anywhere, there would be nothing to hold pressure, so the slightest leak would cause the system to go to zero.
Some causes for a sudden water pressure drop: 1) A big leak on the main supply line. 2) one or more faucets or shower heads opened on the same water line. 3) A utility water pump failure.
Oil pressure as measured by the guage on the dash is usually a measure of the pressure put out by the oil pump and not an indication of a leak or low engine oil level. If you have a leak your best indication of that will be puddles on the ground, on the underside of the engine or a milkiness looking color in the oil (as seen on the dipstick) or in the engine coolant.
You would have a leak in the coolant system somewhere and you need to have the system pressure checked.............
