Just pulling out the trailer it's a 2010 jayco Jay series I had to replace this whole setup last year after finally getting the shower up and running. However I noticed last year there was still a leak in it we only use it a couple of times but we're getting ready to head down to Lake Powell and there won't be showers available where we're going to be. It'd be nice to have something to rinse off with. However that hole which I'm sure is related to like a back pressure or something like that is constantly leaking any ideas on why that would be and what I may need to be able to do to resolve that?
are you in a climate where it freezes? gotta winterize them properly either blow it out with low pressure or run some non toxic antifreeze through it. had this problem once when it got really cold even my toilet valve broke. now I make sure to winterize everything.
