I am going to take the motor in on monday to try and find what the problem is
the problem origonaly when it sounded a little rough

, I must admit i dint take a great deal of notice at first, when your hearing it all the time you dont seem to notice it much.
However i thought it strange that i kept tripping custysfuse iwhilst i was working, pumping ok then suddenly would trip. I put it down to sensitive trip :

after about an hour suddenly no pressure and a smell of burning from pump, although the motor was tmaking a noise and trying to work, too late damadge already done i guess.
