RV Water Lines and Pex Fittings! Eric talks about what RV Water Lines and Pex Type Fittings you should keep as spares in your RV. Pex is a broad term covering the RV Fresh Water System. A water leak can happen at anytime and being prepared to fix it whether the RV is in your driveway or you are on a vacation is critical to being a Hero. Any water leak is bad and should be repaired as soon as possible to avoid any potential water damage and or ruin a vacation. We have compiled a list of the most common water fittings and water lines that are found in an RV or that fail regularly. Here is the Fitting Check List that I recommend: This list has been updated since the podcast was published and can be viewed by using the link below it.

This is Eric Stark with Radio Arizona RV. Today's show is episode number 57 and it is going to be about water lines and fittings and what you should keep in your RV toolbox. And so this episode is based on the amount of customers I have. They come into my store or call and have questions about water lines and what fittings they need, what fitting's are going work. And quite often there's some confusion thinking that the RV Parts guy just knows what an RV has, what fitting goes to the toilet, what fitting goes to a faucet. And in a lot of cases those fittings are narrowed down to one or two. But the question of what size line that the RV has comes up, a faucet takes a 1/2 pipe thread fitting a female pipe thread fitting. Same with an RV toilet, but the waterline going to it might be 3/8 or it might be 1/2.
