Thank you for commenting on this. Finally, a KZbin RV tech talking about this. The flexible hose connected with PEX connectors and cinch ring will eventually leak. Every camper that I have owned has developed leaks in these connections. I always must redo the plumbing. As you mentioned, no plumber would do this in a house because it will leak, and it’s against the code. I think many RV owners are unaware of this significant problem. I still cant believe why this is not all over youtube.

However, the one issue I found in my first year of ownership was exactly what you are pointing out. In my back bay where the water pump, water heater, and water filter are situated, I found 5 joints where the vinyl hoses were pex clamped onto pex fittings, were leaking. I used a mixture of barb fittings and heavy duty worm gear hose clamps to resolve the issues. The dealership just wanted to reclamp with pex clamps. I told them I would take care of it myself.

Wonderful video - thank you! My 2022 Riverside Retro RV was all vinyl on pex clamps and I have fixed at least 12 leaks so far. I hired a plumber to do the first one and then he showed me how to do the rest. I used pex to barbed adaptors using a short length of pex using a pex clamper, and then clamped the vinyl hose properly with a screw-tightening steel ring on the barbed portion. None of them have leaked again but there are still a few places that haven't started and I suspect there will be more leaks from these. I do use a pressure regulator but actually the water pump seems to have pretty high pressure and when I'm not hooked to city water I don't know how to prevent this pressure other than turning off the water pump all the time. The dealer did one repair only - the shower water hoses because the leak required the fridge to be moved to fix. But even then they said they could not repair with barbed connections because they only get reimbursed by Riverside to restore it to the condition to which it was built. To prevent this from happening again I installed cutoffs on these two hoses (hot and cold) from the pump area to the shower so that I can make sure there is no pressure in these shower hoses except when I actually need to shower, and then turn them off again right away after showering. A bit of a pain but better than having to have the fridge removed again for another leak.

Jacob, OK how to safely test the entire water system for a leak in an RV? I made a combo winterizing connection / leak down test fitting. It attaches to city inlet then regulated compressed air. Pressurize the RV, 40 PSI or so, close the valve in the tool that locks the air in the rig and a built in gage on the tool monitors system pressure. By using regulated air and monitoring pressure loss you are not using more water and possible further wet areas. Its a similar test to new construction rough in plumbing system air testing. Tool layout, air fitting to ball valve to pipe T one leg gets the gage other gets male hose connection to RV. Gary 2007 Airstream Classic 30' Slide Out

Since I’m still under warranty with my fifth wheel I’d love to have this corrected under the warranty. However if I bring this to the manufacturer and tell them the plumbing was incorrectly installed I already know that their response will be “it’s installed however production wants to install it” like I’ve heard before when I tried calling them out on installing only part of the roller mechanism on my mirrored closet doors and not the whole mechanism. I’ll most likely have to foot the bill to fix the plumbing which I am not able to do at this point in my life. Praying that nothing else leaks.

Uponor PEX is unlike any other PEX competitor. The connector allow full port fittings by a proprietary tool manufactured by Milwaukee tools that expands the pex which has a memory that then shrinks/compresses the fitting, eliminating the crimp rings in place of a 2nd pex ring that guarantees a secure fit.. We use only Uponor on all of our jobs. It can freeze and then thaw, expanding by 10%. Though Uponor is slightly more expensive, the speed and security it supplies more than offsets the cost.

They put flexible hose at the pump as a sound deadening measure. When the pump hammers if rigid pex is connected it can vibrate on 'something' but the flexible hose doesn't have this issue.

We own a 2019 Newmar motorhome (almost 4 years now) and it is plumbed throughout with PEX tubing. The worse thing I can say about it is that all the tubing is the same color - white. There are a few spots (i.e., toilets) which don't have the PEX tubing, but that is because there is a valve connected to the PEX tubing, and then the flex tubing from this valve going into the toilet area - thus, no pressure issue. And that is the only area where I haven't seen PEX tubing. I can see a lot of PEX tubing, in the basement, under the counters, etc. I think there are other quality manufacturers out there, but I only have experience with Newmar.

My GD TT uses the flexible tubing all over in places it is passing through walls & cabinets wherever the lines aren't a straight run. It is also an annoyance because these rough holes punch through walls & cabinets causing the lines to rub on these jagged openings which cause all of the strange noises one hears when they flush the toilet or flip on a faucet. The flexible water hoses are at maximum static pressure before a faucet is turned on, then as the water flows the hose will slide fore or aft slightly as the running water pressure is less than static pressure. I have tried trimming the openings to these cabinets or walls to make the holes more uniform, then wrapping the flexible tubing with a microfiber towel to limit the jerking the tubing does as it slides unevenly. When I first heard these noises, I thought I had a plumbing leak as the rhythm of the ticking of the line rubbing on the rough hole opening sounded just like water dripping ... A sound one never likes to hear while sitting on the toilet! After about 45 minutes of investigation I came to the conclusion it wasn't leaking in this case, but was a poor execution of a terrible slap together job of my Imagine's plumbing. Although we dreamed of our future toy hauler, due to all of these build quality issues that can't easily be fixed, we are seriously considering having small park models at each end of where we work for the summer in CO (District manager for USFS consessionaire) & play for the winter as a snowbird down south. The rub is that we like to play for a month spring & fall between seasons & was horrified at the cost of Class B's that cost $200K which are Junk in 5-10 years like many autos can be. Having slight mobility issues as semi-retired Boomers, we thought maybe a very small Class C was the right answer, still made from junk, but half the cost of an overpriced Class B. But you pointed out the plumbing issue still exists, so we can run, but not hide from this problem. The Minnie Winnie 22M has a Power Gear small bedroom slide, not the worst at least, but still the problem with the plumbing. This is at best a 3 season coach anyway, but most of the plumbing is ducted away in chase ways not easily found. I see the RVIA certification requires flexible plumbing on the water pump, presumably to limit vibration travel by hard plumbing. However companies like Brinkley purchase premade high quality flexible tubing & connectors where needed. Winnebago & Thor need to listen up!!! Thanks for the education, now more research is needed on my part. Davey & Sheila Knapp

So truth the rv had prior leaks and roof patched and there is inside paneling that needs replaced but it’s really solid. So hoping I can do some of the replacements myself ~ water lines is a definite as bathroom shower and toilet / sink are fine - kitchen sink fine. Etc ~ I’m going to get another shops opinion as well.

I have a 2010 Rockwood mini light and the trailer is plumbed correctly except for 2 fittings at the water pump. They have never leaked and I'm going to fix them soon.

Just stumbled on this video, I liked and subscribed. Great topic, 2021 vanleigh Vilano, msrp 109k, 70 percent of the plumbing was with the flexible junk, I spent 2 half days replacing with pex, no more leaks. Good point on parks with higher pressure than others, that’s when it leaked the most. Not a fan of pressure regulators, I like a good strong water pressure, especially for the shower.
@undercoverrvtech Жыл бұрын
Another consequence of high pressure on your system is water pump check valve failure. I see this problem a lot. Symptoms include fresh water tank filling and overflowing while connected to city water, or the pump running but not building any pressure. I've have many clients panic because they could not winterize before an impending cold snap due to this problem. You could install a valve to cut off the pump from high back pressure to prevent this. RV's are not equipped with a valve like this because it is expected that you use a regulator.

Thank you for this video!! As @rdance3 mentioned - would you consider doing a video on fixing this issue - swapping it out. Our 2022 Storyteller Overland Stealth mode has had several leaking problems - we just thought from rough roads and vibration. We recently took it out in freezing temps (supposed to be 4 season) and in the particular box where the plumbing connections are, it froze - though the rest of the van and water tanks were fine. That caused the lines to swell and ALL the clamps to loosen. My husband has had a heck of a time replacing the clamps with the kind that you use a screwdriver to tighten. Unfortunately many of them are still leaking and we are wondering if there is damage to the hoses or what. Trying to figure out the best path forward and how much we need to replace down there. lines? clamps? connectors? A video helping with how to correct the problem would be much appreciated.

Would a standard metal screw tight plumbing clamp be the best choice? I would appreciate your wisdom. Thanks, Wayne

What you described would create more leaky joints. I only reccomend using flexible tubing if it is a pre-made assembly like I was showing in the video. So unfortunately a proper repair requires removing all the flex tubing that was cut to length and attached to PEX fittings and replacing with PEX, or installing a PEX to 1/2mnpt adapter so that a pre-made flex hose assembly can be attached.

Good info! I'm glad you mentioned the pressure issue. We are on our fourth RV, currently a 2017 Class A and have always used a water pressure regulator which I set at 40-42psi. I use an adjustable regulator with a built in gauge as I believe the ones you show are simply restrictors not regulators. Being on several social media camping related sites I've come to the conclusion that a heckuva lot of leaks are self induced. I don't understand the obsession with high water pressure, what does it prove?
@rossbagley9015 Жыл бұрын
They're pressure regulators. I tested this using one of the adjustable regulators and its gauge. My house has 100psi water. I set the adjustable regulator to 80psi and then put it downstream of several non-adjustable regulators. I had one from camco and a few other no-name ones I bought off amazon. They all regulated the water pressure well below 80psi. Some were 50psi, some 40-ish, one 35. But all regulated the pressure, not just flow rate.

I have had at least 10 fitting leaks on my 2022 RV.. The issue is, the pex itself. Draw a short line with a sharpie on the pex pipe by the fitting at the connection to a faucet. Then hand tighten the nut on the fitting. You will see the line/pipe rotating with the fitting nut. This is because the seal sticks to the pex, turning it with the nut. PEX tubing does not like being rotated, so it will unwind the pipe and also loosen the fitting you just tightened. The solution is to hold the pipe with one hand, then tighten the nut with the other. This keeps the pex pipe from twisting with the fitting nut.

I understand you shouldn't use pex within 18" of a water heater. My water heater has a Tiara ROC Water Heater by-Pass hose Assembly where both bypass valves screw directly onto the tank and have integrated pex-style male connections for the blue & red lines. However, Winnebago has inserted about 18" of flex tubing between the pex and the bypass assembly. Should I remove the flex and connect the pex directly to the bypass assembly? Or maintain the 18" separation between the tank and the pex?

I would only use PEX A if using PEX A fittings. It would be a great way to plumb an RV, but I don't recommend installing PEX A on a PEX B fitting. A PTC fitting like SharkBite can work on both if installed correctly, I don't recommend them as I've had the o-ring inside get damaged during install and create leaks. If installed correctly they are fine but are more difficult to install than PEX B tubing, fittings and cinch clamps in my opinion. @@tkilg7169
