Yeah sounds like they used the wrong waterlines. Was that for your outside shower?
Looked like you have it fixed correctly now. Nice job.
Last year I was forced to learn so much about RV's. Cant count on the local CW - plus most of the time I can fix myself on the cheap in 30 minutes or an hour.
Good thing I dont mind getting my hand dirty and I have plenty of tools on board.
