So I've peruved for answers to this question, not sure whats going but anyway here we go. So we have a 99 Starcraft starmaster and we love it, I've updated the floors, painted the cabinets, added new hardware and refinished the countertops with countertop paint and it looks great. Anyway long story short, ours has the shower/toilet combo and for whatever reason, after firing up the hot water heater we get hot water from the sink but not the shower...I followed the pex lines that come from the shower and couldn't find a shut off anywhere. we get cold water just no hot. I've never tried using the water pump and water tank as we always have hookups where we usually camp, but it doesn't seem to make sense that it wouldn't work when connected to city water...unless there is a shut off directly at the hot water heater.... but if I remember correctly it branchess with a T off of the sink (not positive it's closed and stored right now), so what gives? do I need a new faucet? it seems like the hot handle turns just fine and I think the valve is oppening when it turns....am I missing something? Help! We're hoping to get her out and cleaned up for the first trip of the season and I want to work on a better solution to drainage, but can't work on that until I figure this out. Thanks Guys!
