The same one you repaired last week?
Well....
The water pump has a pressure switch on it... It detects when you open a tap or flush the bog and starts the pump...
The pressure switch packed-up the other week and I spent a day changing it.... you have to saw all the pipes off and replace them...
Today, the pump packed-up...
Went to the GIY shop and the bloke said, "you should have changed both together"...
I fecking know that now!
