Vacuum Hose Size Question

[ShineTimeDetail]

So this may be a dumb question and maybe I just need to go to bed haha but I bought a 16 gallon 6.5 hp vac. It has a 2.5 inch hose and it doesn't seem like much more power than my 5 hp with a 1 7/8 hose. If I use the crevice tool attachment from my 1 7/8 hose on the 2.5 inch hose will I still get the same suction as I would with the 1 7/8 hose?

The crevice tool on the 2.5 is much bigger the 1 7/8 one. Basically my 1 7/8 hose has a crack in it so I can't use it any more. Can I just use the 1 7/8 crevice to to get the same suction as I would with the 1 7/8 hose?

Does that make since? lol

Thanks!:dblthumb2:

Try it and see how it works then report back your findings. Worse that can happen is that your new 2.5" hose will collapse but I highly doubt it. I was at the Salvation Army thrift store the other week just looking around to see what they had and I found a brand new carpet extractor hose setup that has the vacuum hose (1-7/8"), the liquid feed hose with trigger and nozzle and the end suction piece that is dragged across the carpet. I will be trying to locate a cuff that will reduce from 2.5" down to 1-7/8" in size and attach my pump up garden sprayer to the end of the liquid feed hose and hook all of this up to my coin op vac unit in my van.

I probably won't mess around with this until spring but I'd still be interested in your findings. Be adventurous and give it a shot.

Forgot to mention that I paid $2.99 for the extractor setup brand new. You never know what you'll find in one of these thrift stores.

The suction will depend more on the lift (measurement of suction) of the motor design -- not just raw phony hp numbers. Many shop vacs are in the 40 to 60 inches of lift range. A smaller hose can increase velocity at the reduction of cfm but two small of diamater will just starve the motor and flow will drop off.
