I thought you posted earlier in the year that you had brought in a system from New Zealand.
Which is ironic as we export to both there and Australia.
Not New Zealand....I got it sent in from Australia.The vac was crap though so i want to replace that,that is why i am asking what size vac is suitable.
The pipe work for sucking the crap out of the gutters is great,it needed a bit of modification,but my mate did this in his spare time.
Dont worry Glyn...Your invention is safe....
