My outside shower never did work very well and produced a dribble at best. I started looking into why, I replaced the rubber hose with a stainless steel flexible hose and found out the rubber hose at the facuet end did not have a rubber washer and was leaking into the trailer (only minor). I also found out their is a small hole at the end of the sprayer where the hose attaches which is so small that it limits the amount of water into the sprayer. I enlarged the hole and put a washer on the facuet end a viloa, a good flow to the outside shower.
