There is nothing special about my
Butlers except the Y splitter I thought about in 2008.
Butler now makes a really clean set up for this so you can have the convience of run a live hose reel (with never leaving any hose on the reel) or just take off what you need and plug into the y splitter... Plug off the rest on the reel.
Also we have the larger blower and high heat.
Your vac release is important it is tuned to 15-16 hg and clean waste filters.
Keep the plumbing clean also with occasional descaling.
It's all about keeping it in good basic running shape.
We also run the 2.5 hose and the 2.5 inch hose reel. We carry 100 feet of 2.5 on the reel and carry in a section of 2 inch (or more if needed)
A Saigerized edition could also have a regular 2 inch hose reel and get performance but our 2.5 I feel really can give some more advantage.
