Pex diameter

[Frankie Z]

I want to purchase pex tubing in case I develop a leak while camping.
I have a 2650S sunseeker. What size diameter pex do I need and what tools and fittings are recommended to have in case of leaks.

Thanks

Likely 1/2 inch.

Shark bite type.



for those all you need is this.

The Sharkbites are a bit pricey but they sure work nice, easy to install, especially if you have to do a repair in some tight, hard to reach, body contorting spot as is often the case with RV plumbing. In a lot of the spaces you will be hard pressed to get in there with a pex ring crimping tool, so the Sharkbites are awesome. Easy to find in most major hardware stores.

I also carry several sharkbite assorted fittings and half dozen 3 ft lengths of pex for emergencies. All the lines in our Lexi that I've been able to access are 1/2 inch, so I imagine your rig is the same.
Assortment of O rings, roll of teflon tape, some rubber O-type rings for fresh water hose are also good to carry
Also, get a small tubing cutter, one of the small type thats easy to get into small areas. Invalueable little tool, and necessary to get a clean edge end when working with pex.
