I've always used one so I wouldn't know the difference. I do know that since I went to a 1 inch supply hose it seems to allow my tank to fill faster! Even a couple of my guys noticed the same thing!
Thanks! Those are 18" cox reels on the stackable kit they make.We use 1.5 on the hydrant and 3/4 on supply hose. I might increase up to 1 inch. with an 8 gpm & 5.5 running we can run the tank dry fast.
I like the reel set-up on the back of your trailer. Is that something you fabricated yourself? I could use more room and considering something similar.
