All kinds of things can cause loss of pressure. We need real facts to figure out why- Please resubmit with more information about your water supply.
Insufficient water pressure or incorrect pipe sizing
This could be due to a number of problems. 1. The pressure control valve which has a filter may be blocked. 2. The water pipes you have may have a blockage or be corroded. 3. The council where you live may have turned the pressure down in the road.
The simplest answer would be that the screen in the spout is clogged.
You have to undo the aerator at the end of the faucet and clean the screen or plastic water saver out. It will be plugged with sand or sediment.
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.
The water will boil when the fluid gets hot. Steam in the fluid will causes a loss of hydraulic pressure.
That depend where the pressure is dropping. Possibly a plugged valve under the sing where pressure loss is seen, or possibly a leak under the floor, especially if piped with Poly-B.
drink out of the toilet.......
Sounds like a bad/failed water pressure regulator.
Plasmolysis is the process where water leaves the plant cell due to osmotic loss. This leads to the shrinking of the cell membrane away from the cell wall. Turgor pressure, on the other hand, is the pressure exerted by the cell wall against the vacuole and cytoplasm. Plasmolysis occurs when there is a loss of turgor pressure in a plant cell.
Pressure loss in a venturi is typically caused by friction between the fluid flow and the venturi walls, as well as disruption and mixing of the fluid stream. This pressure loss is necessary for the venturi to create a pressure differential, which allows for measurement or control of fluid flow rate.
Bulliform cells lose their turgidity during excessive water loss, which can be caused by factors such as high temperatures, strong winds, or drought conditions. This loss of turgor pressure causes the leaves to wilt and curl, helping to reduce water loss through transpiration.

Defective bladder / low pressure inside the tank
it causes a decrease in atmosperic pressure A+
Someone is stealing your water.
