Humm,I guess I should check on screwing the ends together,but the problem with that is that I use quick disconnect on everything on the water panel. Both grey and black water rinsers have back flush valves,so I can just switch the hose end from one to the other.
What really ticks me off is spending the extra little bit of money for a no kink hose and have it kink up as you're uncoiling it for the first use.
One of my other pet peeves are the campgrounds that have pressure relief valves/back flush preventers on the spigots that blow water all over your feet when you're not expecting it.
