I have a V3000 for about 2 years now. I have great success with it.
I used 6 inch S&D pipe with pvc reducers to 4 inch S&D thin wall pipe. This thin wall pipe accept my flexible 4 inch hose but with a very snug fit. I try to get as close as possible to the machine with 6 inch pipe.
I made hangers with metal strapping thrown away at the lumberyards used for bindings. Some hangers are made with plastic hanging straps with the perforated holes in the plumbing department.
You will like this machine.
