Right . I took a closer look yesterday and I have to rectify something. Vac 1 it's working fine and vac 2 seem to blow rather than suck. I've swapped the wires between them and made no difference.Where I've disconnected the hose the vac 2 it's blowing air which I'm not sure if it's normal ,and it's going under the machine.I would appreciate any more info as I haven't got a clue at the moment . I have a spare vac just in case something is wrong with vac 2.Thanks
