A swivile between the hose wnd ball valve. Basically your hoses don’t twist up as much so your not fighting them… Ill take a pict tomorrow and see if I can upload it… You need a good swivel and ball valve if you want them to last. Mine also have a quick disconnect so after every use I take the whole unit off as one piece and spray it down with a little oil. I actually have a 2nd one as a spare… I have enough spare parts to start another company…hahahhahah
