Stuart Turner hot water pump in the apartment

Are you responsible for the pump maintenance, or is the apartment owner? I would report it to the building manager, or maintenance man as there may be a penalty for NOT reporting such issues.

I am owner occupier.
The problem has been compounded by my ham fisted attempt to fix the pump whereby I blew the circuit breaker!!
I won't give up my day job...

I know nothing about this device, but you have read the instructions referenced above haven't you?

I have a Standard (positive) twin pump and it keeps running on.
If this pump has just been installed, close both isolating valves on the outlet side of the pump (or the service valves integral to the flexible hoses, if fitted) and see if the pump stops. If it does, then this indicates there must be a tap or outlet being pumped that is open to atmosphere. Check the system and find where the pump is pumping the water to. If the pump does not stop when closing the valves, check to see if the reed switch on either end have become dislodged. Alternatively unclip each reed switch, one at a time from the brass outlet and see if this stops the pump, indicating the float is stuck up inside and needs removal and cleaning or replacement.
