Alot depends on the care given during the service life, and the amount of damaging debris that was "forgotten" by a dutiful prevac. Not to mention the number of times it gets stepped on and run over.
Marty, care to explain what that means? Particularly to the fellow who started the thread? Nothing personal, but you took the time to insert your lofty comment; why not offer up some of those 20 years of experience as well?
i just replaced the blower & hoses with our in plant extractor the 2" hose literally disintegrating kinda brittle we run a verity of solvents through the system so I'm not surprised was it's about 9 years old
I used high quality hose and replaced every 4 years. Partly this was for appearance to the client as well as the effectiveness of the hose.
It was not about to fall apart when I changed it, but it made sense that the hoses would gradually deteriorate. I wanted to keep things running top notch. So I had a schedule to replace hose just as I did for replacing filters, changing oil and other maintenance items.
i guess that is why i was looking for input and i got it what kind of hose do uall suggest buyin does anyone know what the hose is called i am tryin too find it in supplier catalogs like mc master-carr
