Modern RVs, made in the last 10 to 15 years, are plumbed using PEX tubing, sometime called PEX pipe, for the fresh water system. In fact, most new homes and commercial buildings use it too. It is so much cheaper than metal pipe and because it is flexible it is easier and less expensive to install as well.

What size PEX tubing is used in RVs?

In RVs, manufacturers typically use translucent non-colored PEX for all plumbing runs. Further, two sizes are used, 3/8-inch and ½-inch. These are the standard size because the outside diameter of the tubing is about 1/8-inch greater than the called-for size. Also, PEX is inexpensive.
