According to a recent YouTube video, manufacturers are selling new RVs with improper plumbing, causing major issues for owners.
Sadly, it isn’t just bargain-basement companies utilizing this technique. Big-name brands are also guilty.
Join us as we discuss the RV industry’s plumbing crisis and what you can do to protect your rig from damage.
Let’s dive in!
New RVs Plagued with Improper Plumbing
In a recent YouTube post, Jacob from Rigor RV Repair illuminated an insidious problem in the RV industry. Many manufacturers are outfitting rigs with flexible vinyl tubing instead of PEX plumbing, also known as cross-linked polyethylene.
Unfortunately, when used along with standard pinch clamps, the combination can cause significant issues and lead to costly repairs. In fact, these incompatible fixtures are almost guaranteed to leak eventually.
Jacob stated that many RV brands are implementing these improper plumbing systems. Although he didn’t call any out by name, he claimed that the problem isn’t limited to low-budget manufacturers. Plenty of high-end names are equally culpable.
This might sound like an issue you’d only encounter in a retrofitted camper, but folks are discovering the setup in brand-new rigs fresh off the lot.
Jacob is a certified RV technician as well as a licensed general contractor, so we trust his opinions on these types of functional problems.
Problems Caused By Faulty Plumbing
Flexible vinyl tubing is prone to swelling, especially when handling high water pressure. When used in conjunction with improper fittings, plumbing leaks are inevitable.
While some leaks are immediately apparent, those that aren’t pose a severe risk to your rig. Water accumulating in hidden spaces can encourage mold and mildew growth, quickly becoming a health hazard. In other cases, leaky pipes can result in swelling wood fixtures and damage to rust-prone metals. Eventually, you may encounter structural issues with your RV’s frame, floors, and walls.
Sadly, no dehumidifier can counteract ongoing leaks in your camper. You need to address the source of the problem to avoid catastrophe.
Why Do Manufacturers Install Bad Plumbing in RVs?
It’s probably no surprise that money is the primary motivator for this improper plumbing technique found in many RVs. Builders can install inexpensive braided tubing and PEX clamps, which will work for the early days in your camper. However, significant complications can begin to appear within months or years.
So, why do they take the risk? In Jacob’s words, “It’s cheap, convenient, and they can.”
Unlike brick-and-mortar construction, RV manufacturers don’t have to meet specified code requirements for plumbing to pass inspection. In turn, many builders incorporate this inferior option into their systems to avoid the added work of measuring, cutting, and piecing together the proper PEX tubing.

What Can RV Owners Do about Improper Plumbing?
Since RV manufacturers aren’t technically breaking any laws or industry standards by outfitting their rigs with bad plumbing, you won’t be able to sue for damages or seek compensation from the builders. But you can do a few things to combat the problem.
#1 Properly Winterize Your RV
Campers who discover improper plumbing in their RV don’t have to throw in the towel just yet. While leaks might feel inevitable, you can take certain steps to protect your rig.
Thoroughly winterizing your camper is one of the best ways to avoid leaks. This process includes draining all your holding tanks and ensuring no water remains in your pipes. Then, add antifreeze as needed.
Proper winterization will keep your lines from swelling, which can help you prevent costly damage.

#2 Install a Water Pressure Regulator
Another way to reduce the chances of a leak is to install a water pressure regulator. After all, increased water pressure is one of the leading causes of swelling and leaks in these incompatible setups.
That being said, one of these devices is a wise investment for any RV owner, even if your camper doesn’t include improper plumbing.
A water pressure regulator will protect your rig from excessive pressure commonly found at RV parks and campgrounds. It’ll safeguard your camper from damage and improve the lifespan of your pipes, appliances, and accessories, such as water purifiers.
#3 Don’t Buy RVs with Bad Plumbing
If you’re in the market for a new RV, it’s essential to thoroughly inspect the rig for the warning signs of improper plumbing. Look under sinks, behind toilets, and anywhere else you might find water lines to see what type of pipes you see.
Flexible vinyl or braided tubing is a red flag, especially if it makes up a large portion of the system. Of course, it’s often necessary for areas requiring movement or in spaces where pipes must curve around walls or fixtures, but pairing them with the correct fittings is paramount.
When you spot this material, inspect the clamps to determine whether or not the manufacturer used the appropriate type. Flex-tube fittings should have barbs and O-rings that provide a snug fit, while those for PEX tubing only have ridges. However, it may be impossible to see these details unless you take apart the system, so learning to recognize these items will work in your favor.
Remember, purchasing an RV with bad plumbing tells the manufacturer you’re happy with an inferior product. For better or worse, the best way to encourage change is with your wallet, at least in this situation.

Remember, a water pressure regulator and proper winterization can go a long way toward protecting your rig from costly damage!
