Water pump is not doing automatic
You have a Water pump that is not doing automatically off/on, even though all the water flow points are closed. How the problem to be solved? There are many things to be understood for your convenience.

How the Water pump Works.
One of the water pump function is, it switches on automatically if one or more draw-off points are on and flowing water (e.g. taps, washbasins, toilets, washing machines, Dishwasher etc...)
And It switches off when all water flow points are closed.
The pressure kit/switch is controlling the automatic activation & deactivation of the water pump. The pressure switch/Kit depend on the type of Water Pump, this can be a pressure switch, a Press control, or an 'active' system. These systems only measure the pressure in the pipes between which the pump has been placed. When one or more draw-off points are on, the pressure will go down in the pressure gage, and the pump will run.
However, what do you need to do if the booster pump continues running / operating when all draw-off points are closed?
Causes and related solutions
1. Air leaks into the system.
2. No non-return valve or foot valve attached to the suction side or broken and leaking.
If your Pump is continues running, then there must be an air leak in the water pump or somewhere in the water flow unites or pipes. The water pump unable to build up full pressure, and therefore cannot reach its deactivation pressure level.
Or the non-return valve or foot valve attached to the suction side or broken, The Water is not standing in the suction side pipe and the water pump is unable to build the pressure to activate the pressure switches or kit. As result the water pump is continues running.
Solution: check all the water using points /pipe and fix them. Check non-return valve or foot valve and fix it.
