I run 35’ of 2.5 off the custom waste tank lid.
I then have a 100’ section of 2”...
I then have a 30’ piece of 2”, that I refer to as ‘shorty’.
All my hose cuffs are standard, I put them on the hose, first using Teflon pipe tape, then use electrical tape to secure them....
The ‘links’ between the cuffs are 2” stainless steel.
Air leaks are your enemy....
I also over spin my 47 blower, standard is 2850, I run it at 3450...
Even at 200’, I use earplugs everyday....
I let you guess why...
On really big jobs, I’ve got 250’ of 2.5, then run 2” the rest of the way....
On commercial jobs that require speed, I will run 2.5 all the way, except the last 30’ (shorty)..
Is 2.5 a PITA?
Of course it is, but the results are worth it to me.
BTW, 1.5 whip hoses are for home vacuums or for riding in a horse drawn carriage.....
