Okay, so now the shower works. Don't know why, just turned it on and it started to flow (slowly at first.) Still no water at the kitchen faucet, however. The owner's manual shows no valve (I winterized and closed no such valve) for a cross-over, and no water is pouring/leaking out. A crimp in the line is doubtful because it is concealed under the floor. I'm in the middle of Zion/Bryce Canyon, UT, lucky to buy gasoline. No service centers. Anybody else out there with some ideas? It would be nice to do the dishes at the kitchen sink.
