I have an airflex 400lx, it won't work every time I switch it on it trips the electric.
If I buy a new pump can I install it myself or should I contact a sparky.?

Fairly easy job replacing the pump if you have a basic level of mechanical experience. Take images of everything before removing any components for future reference.
Are you sure its the pump causing the electrics to 'trip' and why?
