Anybody know what I would need to build my own sight tube? for my vacuum hose that is , so I can see what is being vacuumed and extracted out of the carpet. The customers sometimes like seeing the dirty water.
I have used sight tubes from Interlink and rotovac and all they are is some clear tubing with vac cuffs. I wasn't impressed with the flimsy cuff on the last one I got from Interlink. I am thinking of making one and thought I would ask if anyone had done that.
BTW: I dislike the 15 character restriction while posting.
