RV water lines have changed over the years. Older style RV water lines used to be a hard plastic with a lot of metal elbows and crimp ends. These lines were very susceptible to freezing and would have leaks caused by vibrations from driving on the highway.

Newer generations are starting to use plastic pipes with a more user-friendly style featuring flared fittings. Many of these new RV water lines that are being used are residential style or the new Pex ½-inch tubing. The tubing is perfect for RV water lines for many reasons, including the fact that they come in colors – blue for cold and red for hot.

With pressure your RV will get from connecting to city water fills these tubes allow more flow on the inside of the unit and through all of the RV water lines. Plus, Pex does not have a lot of taste inside the tubing so you will not get a lot of added taste to water.

Pex tubing can expand up to one and one-half of the original size without splitting. This is great should the pipes get cold and freeze during the winter months.

Newer plastic RV water lines are easy to work with. You can easily select the lengths of tubing you need and cut off with the proper tool. The flared system makes it easy to slide pipe in using a compression fitting over it. Your new water lines can also be upgraded with different features, such as elbows, Ts and shut off valves.

With these new Pex tubing you will have the ability to add things to bigger pipes and relocate items throughout your RV’s water system. There are definitely more options available using the newer tubing systems than the older metal and less durable water pipes.
