I have just gotten to warmer area and dewinterized. Everything seemed to be working well and then my wife and I both took showers. We both conserved water by using the on and off switch on the spray. ...
Had same problem on our 2014. Dealer fixed it same way you did. I think they pulled the hall panel out half way and tightened the fittings. Had it there for a leveler problem so no extra aggravation.
