Plumbing issue in '13 330RL
We recently purchased this trailer from a friend. When he bought new, he had a water leak issue that seemed to self correct. (no water on floor).
When we were going through and cleaning up interior, wife discovered water on the floor. We deduced that there was an issue with the lines going to the shower faucet. The tee in the storage area was different than the rest of the plumbing as was the tubes going up to the faucet. Long story short, found that the cold water supply had a screw through it!! Looking for a recommendation of what type of tubing to use. The pex that is in the rest of the trailer is too stiff to use for the shower valve lines.
