Old Style Plumbing

I recently did some plumbing work and found a few options. The stuff at the big box stores like Home depot and Lowes is different than the connections in most RVs. The Flair it fittings are probably what would be there and are still in many new rigs too. You can find those online at the lowest prices. Then some dealers may have some too but I found the local stores were charging double what online sellers had them for. The big box stores have different kinds and sizes without the same type of connections. They also have the shark bite style under that name at one of them and something else at the other. I think Lowes has another name. They are pretty easy to use but I don't know about long term. They are kind of a pain to get back off in tight corners. I did a couple wrong and had to undo them and it was tough when you don't have much room to pull on each section.
