The pump is 5 years old I done the bucket test on it were i disconnected the load side pipes and let it run into bucket and it runs perfect no cutting out !!!?????
I have a Stuart turner pump in the garage which supplies the entire house hot and cold water . I have had pump serviced by a engineer as it was messing about , when you turned a tap on anywhere in the house it took maybe 3sec for the pump to kick in the once started it would run for maybe 3sec...
