Plumbing question
I was wondering if anyone can answer this. What is the size of the pipe keystone uses in the Rv? And will shark bites work on them? I have been told it is all PHX pipe but plumbing I really suck at.
All thoughts welcomed

Typically 1/2" and the newer "push" Sharkbite fittings are the cat's meow over older sharkbite fittings requiring special rings and tools. Either are better than previous options IMO. Just put a cutoff on the water line to the toilet...took all of 15 minutes.

Yes, 1/2" PEX. Sharkbites work great, but are expensive. I bought the tool and crimp rings; not sure it is worth the trouble.

I had a small shed/cabin to install some plumbing into and purchased this tool to crimp the rings, so didn't buy it exclusively for working on the trailer.

The cost is cheap enough that after purchasing several sharkbite fittings, the crimper becomes less expensive so you can use the crimps and the fittings. I found that Lowes carries the full line of fittings for the 1/2" PEX along with the rings.

I agree with Bob Rohrman - buying the crimping tool and rings (stainless steel was my option) pays for itself pretty quickly. Shark Bite push on fittings seem to have their fans and detractors, reliability-wise. Rather than worry about a push-on fitting coming unstuck while away from the rig was my main motivation for going with crimp-on rings. I have removed a few due to re-design (mistakes), and that was quite the exercise. No more fear of them coming off: I am an official convert to PEX with crimp rings.

Hey Leftie, I have a pex leak at a T fitting at the house ( crimp type ) can I remove old ring and replace crimp without cutting the old crimped part off of Pex? Or can I just try to make the crimp tighter. Ring has been on for about 7 years.

When I have tried to just fix one part of a two or three part plumbing connection, I could not convince myself that I could fix one "leg" without damaging something else. So...., I would cut out the three-way, add PEX extensions, and get a new "T" fitting, and crimp it into the extended PEX lines. My experience cutting the stainless steel rings off was probably a reflection of my newness to PEX world. Perhaps cutting off copper crimp rings may be less destructive, but I have not tried that side of the PEX usage.
Overall, my advice is to err on the side of caution: cut out the bad parts, measure carefully, and insert new fittings and new PEX line as required. Chasing leaks in a rig or sticks-and-bricks is usually not fun, so if you can minimize the weak points, go with new parts.

Thanks so much for the quick response. I'm going to order the tool from Amazon. I'm going to change all fittings that I disturb. 👍🏻👍🏻✌🏻️
