When PEX goes horribly wrong

[@elBusDriverKC]

First time I did pex work, if a cut wasn't perfect or a crimp wasn't perfect I redid it. It did cost me extra time and money, but helped with peace of mind. I called my plumber friend out to check my work. I was told my pex work was high quality plumber style work. No leaks from the beginning to now which is about 5 years later. That's definitely when I fell in love with pex but also learned to respect the pex. It has it's limitations for sure.

[@gebronthomasson6960]

The clamp is a better method vs. the crimp..in my experience..now granted the two jobs I’ve been involved in are only less than two years in service BUT as of yet no leaks..and i know there is no doubt that we indeed did not make perfect cuts and clamps

RESPEX THE PEX

[@IppiopaidFEEDBACK]

This was excellent an tutorial and review of shotty work!
Most of the plumbers that I have worked with as it assistant never do the work as the manufacture specifies. Everybody always wants to cut corners and they say the magical words “that should be fine” which always annoys me because I feel there’s too many variables with the word “should”.
The only thing that annoys the hell out of me is that PEX is so much faster than soldering and yet people still can’t take the little time to do it right. All of the new construction materials and tools make the job so much faster, which allows for greater productivity but doesn’t always lead to better craftsmanship. I think that’s just a flaw in human nature trying to get things done as soon as possible and not taking pride in workmanship.

[@MyFortressConstruction]

So I oversee a gamut of trades and I have to consistently remind them of manufacturer specs., building codes, aesthetic details, as well as common sense approaches to installation. Contractors need to step away from the mass production model of business and get more hands-on with their subs if we are going to see a change in work quality.

[@jerrymalinowski9736]

So true. Ironically, often they (the city) require you to use licensed workers which cost a lot more , that come with attitude, and often you get very poor results. I’ve concluded, if you want something done right you got to do it yourself. At times, I didn’t want to break my head learning a task so I contracted it out to licensed workers only to have to get poor results then having to learn it myself anyways and then fix the poor job. They just don’t care most of the times. Don’t want to generalize, but sticking to my policy has worked the best for me

[@reggiekenner1527]

I spent 5 days in the attic of my rental house a couple years ago replacing galvanized hot water lines from the 70s. A friend, who had been a plumber, told me about PEX. I used only brass fittings and the pinch-type clamps. I've been up there since to check for any leaks and found none. I should note that I live in Southern California so freezing weather is not a problem.
I was unaware of the requirements concerning distance from the nubs but I cut straight and pressed the PEX all the way to the nub before clamping. Fingers crossed.
As my pal told me (I was 70 when I did that work), "Attics are a young man's game"

Great video. As a general contractor (or even a homeowner) you don't need to be an expert in every trade, but ultimately you are the one who has to identify poor workmanship and get it rectified. It takes gumption to challenge a proud tradesman who has practiced for 20 years, but believe me, there are guys who have been doing it wrong for 20 years. I came across one sub who knew all the best practices fluently and guaranteed that he abided by them. 6 months later, when all the tile of two bathrooms was torn out, it was plainly obvious that he outright lied about taking the protective measures against water intrusion.

[@MyFortressConstruction]

Yes, it's unfortunate but I find that I have to know the technical aspects of every trade.

Both PEX A & B are challenging to use in a remodel. with corners and tight spaces to crimp in. I need those plastic fittings with the stops. I used to use tape on both sides of the crimp ring to insure my ring didn't slip while crimping.

[@MyFortressConstruction]

👍 You can also take the rings and tap them on a hard surface to make them slighlty oval and then they won't slide around on the pipe. Both systems have their pros and cons, but I will continue to stick with copper soldering and PEX-B because the only real issue is that they are difficult to install.

There's nothing wrong with Pex B / crimps. You just need to know and care about what you're doing. I used it 10 years ago for the first time (not as a plumber) and my cuts and crimps were cleaner that whatever this guy tried to do. A crimp remover goes a long way too. You can cut out a section of pipe without having to cut out entire fittings. Granted, they work a lot better on brass fittings than plastic which is why you should use brass.

You can see that the crimping rings are no longer "rings" they are flared out and flattened. I have never seen such shoddy work and I'm not even a plumber.

[@staberdearth3130]

Great video for understanding how to properly install PEX B crimping. I note that there are drill plates over the drain lines but no drill plates over the PEX B lines. I opted for the PEX A system with expander fittings for my own home as I find the system somewhat superior and the added cost minimal for such a small installation in my case. To my mind, the method has less of a chance of making a bad connection.

[@MyFortressConstruction]

Yes, you do have to have steady hands and better coordination with Pex-B. You also have to think ahead, because you can get yourself into a situation where the tool can't reach. The flow rate also makes you up-size on the trunk and not share too many fixtures from 1/2", however it is stronger than Pex-A and I trust the copper ring more than the elastic collars on Pex-A. I don't think either one is inherently different though, and life span should be the same, but I've found 30 year old crimps under old mobile homes that have survived many freezes and thaws and they're still going strong. Can't say the same for Uponor because it's such a young system. Course it comes down to personal preference, biases and ol' plumber tales since neither system has been around for a century.

[@staberdearth3130]

[@solarsynapse]

What did you find out with your question? I don't think the B will shrink back.

[@dansr6333]

You can crimp A pex . But do not expand B pex to go on expansion fittings. You would be counting on the expansion rings only to go back to size not B pex. If you expand just right it can work but definitely not recommended. A pex is special with its memory to go back to size.

[@twbrkfd1733]

The problem with this particular shower valve is the installer INCORRECTLY DOWNSIZED the pipes by going to 1/2 inch PEX and this is NOT a valve DESIGNED for PEX. A valve designed for PEX will have PEX connections AND will have restrictors to limit the flow to the tub taking into account the smaller ID of the PEX. The flow rate of 1/2 inch PEX is NOT the same as 1/2 inch NPT nor 1/2 inch copper. A simple 1/2 inch steel or brass nipple from the shower valve to a 1/2 NPT drop ear elbow would have fixed it.

We've had big issues with the brass fittings around our area because of the corrosion issue. leaks within 5 years from the brass fitting swelling from corrosion and in some cases actually breaking the rings.

It sucks that you can pressure test the system and have not leaked at that time, and that is why I like copper

If an installer puts half the attention and care into a pex joint that they put into a properly done solder joint there really shouldnt be an issue.
Ive worked on a big remodel job. A house plumbed with copper that held pressure for a while(hours or a day maybe) and seemed fine initially. A line burst when noone was around for hours and caused a good bit of damage to subfloors etc. Turns out a 1/2" fitting got prepped and fluxed but not sweated. Was a tight enough fit and sat long enough with flux on it before getting pressurized that it held pressure (probably 50 psi+) for hours with possibly a tiny drip. It wasnt one of my joints, I believe i wasnt soldering yet with that company.

[@MyFortressConstruction]

If I said they were less error prone, that would be a mistake. Expansion fittings for Pex-A are much more user friendly to install, which is why plumbers prefer it. What I mean in the video is that Uponor fittings are more likely to leak than Crimp rings if they were both installed correctly. Pex-B has a higher burst rating than Pex-A and if there is movement on the line, or if it is exposed to heat or cold, Pex-A is more likely to develop a leak over time.

[@DevilTravels]

@@MyFortressConstruction Pex-A should only use crimps and Pex-B can use either Uponor expansion rings or crimps? Is that the difference noted?

[@MyFortressConstruction]

@@DevilTravels PEX-A is a much more flexible pex tubing that uses expansion fittings like Uponor. You can't use crimp fittings on pex A. PEX-B is what you will find in big box stores and it's less flexible and utilizes SS cinch, SS crimp or copper crimp rings. Pex-A is easier to install if you have a battery powered expansion tool, PEX-B is easier for the homeowner because it only requires a $50 manual crimper. Pex-B is better in my opinion for it's durability and strength.

[@DevilTravels]

@@MyFortressConstruction Thanks for this information. It seems to support other information I am getting.
It looks like PEX-B and crimping is the direction I will go for my cabin plumbing.
I just need to make sure the crimp is directly over the 2 nubs on the brass connectors.

[@elbuggo]

@@MyFortressConstruction - you can use crimp fittings on Uponor PEX-A piping. Any tubing labeled SDR-9 can be crimped. Uponor is the only tubing that can be expanded, but its also SDR-9.

[@davidperry4013]

I prefer copper over PEX. It’s expensive but worth it. If you screw up, just resolder it no fittings to throw away. Also, you will find out that you made a mistake right away once you do a leak check instead of later down the road and paying up to tens of thousands of dollars for water damage. Also, copper is anti microbial.

[@gaewing]

I had that problem 10 years ago. The note from kohler did not have information on the packaging. Had to tear out porcelain tile as the job was completed. Removed the pex between the control shower valve and the fill spout for the tub.

Yes, a little knowledge really helps to prevent costly problems.

Fantastic video. Thank you 🙏

[@tylerwells207]

Great video, thanks for posting! I did have a question, though. Years past, I used a crimping tool that came with two different “go” and “no go” gauges. As long as the ring fit into the “go” range, one was good, at least I thought. I’ve been reading about over-crimping and cannot find any info as to what the cons may be. I figure the tighter the fitting is, the better, right? The Apollo crimp tool I recently bought comes with the same gauge tool you touched on. Are the lines between “go” and “no go” supposed to line up in the middle of the ring once crimped? And again, if the ring goes all the way in, what’s the harm? I’ve crimped a few couplings that spin once the ring is on, having passed the gauge test, but it worries me. From other comments, it appears that’s normal. The Apollo tool comes with a pressure gauge from 0-3. Any suggestions on where to set it for 1/2” pex rings? At 0, it seemed to fit perfectly based on your video, but again, if the fitting can twist, it makes me nervous it may pop off. Sorry for rambling - any help is appreciated!

[@MyFortressConstruction]

I have never had to calibrate a crimp tool, but you are correct in the assumption that if the ring fits in the "go" section of the gauge after crimping, then it is good. So you can spin a fitting after crimping if you have to, but I prefer not to unless there's no way to avoid it. If the line spins freely, with no initial tightness, then I would think the ring isn't crimped how it should be. As for over crimping, I've never heard of that since jaws limit themselves for the most part, but I suppose there could be a set out there like yours that aren't machined to limit themselves. If in doubt, I would call the manufacturer.

[@truthbetold1855]

[@MyFortressConstruction]

@@krehbein It's faster to install, when you know how to do it, and I have only had one leak from a bad fitting in all of my time of using it, and that leak was evident immediately after pressurizing. It is a more durable pipe and it's easier to work on for homeowners. It's cheaper and parts are more easily sourced. You do have to think ahead about which crimps need to be made first, but that's not rocket science.

My Fortress Construction Good to know. Im have a pex a Dewalt expander, and enjoy working with it. But if I need parts can only get them at a local plumbing supply shop or online. Sometimes using Home Depot would be easier.

My Fortress Construction More durable than PexA? That’s absolutely not true. Uponor is more durable by a large, large margin. PexA is superior in basically every way it matters.

We had a neighbor who built their dream home in our neighborhood. They bought an existing home on .7 acres of land. They demolished the existing home and built a huge house on the lot. For some reason, their dream home didn't live up to their expectations. They sold the home for 2.7M after living there for a year. My takeaway is, incompetent subcontractors can work on homes in all price ranges. Our home is an original in our subdivision (less expensive) and I have had to fix a lot of shoddy work. The last thing I fixed is a leak from the bathtub overflow/cleanout. The iron tub did not meet with the PVC overflow pipe. There was about a 1/4" gap between the gasket and the tub that allowed water to flow down the back of the tub onto the ceiling below and cause stains. This little problem had me consider how issues can be magnified when larger, more expensive homes are built by incompetent and/or unethical contractors. What a nightmare if improperly installed PEX leaks behind walls and above ceilings. Leaks under a slab seem to me to be the ultimate nightmare. I wouldn't build a home on a slab. If you are having a home built, you really need to examine the workmanship.

[@readmore3634]

In the early 90's our shop switched to Uponor (expandable) Pex systems. We all met with a Uponor representative so he could demonstrate how to properly install it. We all received a certification and never looked back. I plumbed a 7 bathroom mansion in La Canada Flintridge Ca. back in 2008. 4 tankless water heaters and miles of Pex. Had only one leak where a wood shaving got into a joint somehow....took 5 mins to repair. Never heard from anyone since.
I walked another water front mansion in Laguna Beach Ca. during it's framing stage and almost ready for drywall. ALL the metal crimp rings had what looked like a layer of rust. Yikes! (Salt water is harsh on just about everything)

[@elnicadrums]

looks like they cut the pex with their teeth.. 🤣🤣... you should get a refund on...🤣🤣👋.. when I install the shower valves I do all the connections with copper..

[@arcadion448]

8:45 - I think it's more likely that whoever installed the Uponor didn't turn their tool 1/4 inch all around when making the expansion. Pex Crimps and Clamps get weak over time as crimping or clamping is forcing the pipe against its natural state. Uponor pipes naturally want to be its original size and you have to force it to expand to put the fitting in. However, if you don't push the pipe all the way in or don't expand it correctly (1/4 turn all around when expanding), that's when you get your leaks.

[@solarsynapse]

The A also does not restrict the water flow, is more flexible and higher pressure at the cost of being 4 times more toxic than B!

[@arcadion448]

@@solarsynapse, you got any proof that Pex-A is 4x more toxic than Pex-B?

[@solarsynapse]

@@arcadion448 Do a search and you will find several studies about PEX toxins. The more flexible A leaches more than the less flexible B. It becomes worse with hot water. I think many of the chemicals were in the water itself. Keep in mind that PEX has less data since it has not been around as long as other types of pipe. It still passes "safety" standards except maybe in California. Some of that is due to the lead in the brass fittings.
Chlorine is toxic to all lifeforms, is highly corrosive to metal and causes plastic to become brittle, yet it is used widely in water treatment. Copper is a nutritional supplement, plastic is not. Of course it is bad if lead solder was used instead of silver!
I would say use PEX B, don't drink any water for 30 days after installation, and don't drink any water from the hot side. Also, if a faucet has not been used for over a week, run the water to flush the line before drinking. Filtering is always good. As always, to each their own.

[@arcadion448]

@@solarsynapse Pex was first used (although not for home plumbing) since the 60s, that's plenty of time to gather data. Furthermore, if a simple Google search can't yield any credible sources along with you not being able to provide one simple link - I call BS on your claim.

[@jeremyhess7977]

Great tutorial...This demonstrates one of the major problems with PEX-B.
PEX-A doesn't have this issue and is easier to repair.
The other issues with PEX-B are that you can't heal a pinched piece of tubing (it lacks memory), and you have line loss through the fittings which can potentially restrict total volume vs. PEX-A fittings being full sized since you expand the tubing and fitting collars over the fitting the I.D. on the fittings and PEX-A tubing is the same).
Also, if you get a tiny leak with PEX-A, you can usually kill the water, drain it, and go over the fitting with a torch or heat gun, then let it air cool to get it to "remember" it's original size and make a positive seal on the fitting....can't do that with PEX-B. You have to chop it out if it leaks.
Yeah... I just hate PEX-B. I'll admit it. LOL

[@nvrdwn3140]

The most important rule for ped b is always go up 1/4 in size than code says. Code states its size based off the id of copper pipe. It takes 3/4 pex b to have the same id as 1/2 copper because of the fittings for pex. I use pex a and typically only need two or three fittings which helps flow.

[@MyFortressConstruction]

I do size up, but you don't need to size up with everything. Most valves and fittings in a house restrict the flow of water to smaller than what 1/2" pex-B will be able to provide. It's only an issue when you are providing enough volume to a high flow faucet like a tub filler, or multiple fixtures are feeding off the same line. While it's not a perfect formula, due to fittings, length of pipe and psi coming into the house, my rule of thumb is 1/2" pex can provide a maximum of 5 gpm and 3/4 pex can provide 10 gpm. That's if the run isn't more than 30' or so from the main trunk/manifold. The longer the run, the more the psi drops at those flow rates. If I am putting in a tub filler then I am bringing over two 3/4" lines (hot and cold) and connecting to a TMV which will have 3/4" npt connections anyways and I don't have any issues since most fillers are between 8-14 gpm. Hot and cold 1/2" pex lines going to a shower valve with one shower head is totally fine too since it only requires 2.5 gpm. Where I see people complaining is when a 1/2" trunk line is servicing an entire bathroom. At least use 3/4" to each branch...

[@wallacegrommet9343]

Pex is relatively simple, but not exactly easy. It demands perfect cuts and crimps every time, and getting the crimper into some locations is a puzzle, particularly on renovations.

[@SuperVeeZee]

@@wallacegrommet9343 Uponor is definitely DIY-er capable, much more so than any crimp style I've seen. I'd go so far as to call it easy, especially if you're already the kind of person that's mechanically inclined. Cut the pipe square-ish using a cheap cutter, and it does not need to be perfect, put the ring on the pipe until it stops, expand the pipe until the tool bottoms out, and quickly insert the fitting until it bottoms out. Done. Apply heat as necessary in cold conditions. Any more, two power tools would make anybody capable of running any kind of water line used in residential and light commercial applications. An expansion tool, and a press tool.
I work for a wholesaler, and I've turned several DIY homeowners, that want to do as much of it themselves as possible, into quasi-plumbers. Buy the M12 expansion tool kit, do the work, then sell the tool kit off afterwards. You lose $100 on the tool kit in the secondary market, but saved a bundle on rental fees.

You are 100% correct. I'm a retired master plumber that ran my own repair business for 45 years. Biggest problem with the work force is lack of proper training and no sense of pride in their workmanship. The person who did this work probably sees nothing wrong with this shoddy work. I truly think that's something you can't teach. A person either has it or they don't. If they don't, they do not or can not see anything wrong with crooked pipe installation, hose bibbs not flush with the brick (sticking out 3" from the brick), leaving dirt and grease handprints on a tub or sink you just worked on, and literally too many scenarios to list or imagine. A guy with pride in his work can look at workmanship and immediately know if it up to proffessional standards. The other guy can't, and to be honest , probably doesn't care. They are the plague of the plumbing industry.

I prefer automotive styles stainless Oetiker cinch clamps, ASTM F2098, easy to remove in case of a screw up, can cut the pipe and re-use fitting. Seems more idiot proof than crimping copper rings, cheaper and smaller tool, requires less force and can crimp in tight spaces.

[@bnasty267]

Totally agree. The tool also pretty much prevents you from putting it too close to the base of the fitting, because it gets in the way. These Oetiker clamps have been used for decades in automotive and carbonated drinks. The crimp rings are probably fine, but they look a little too much like Poly-B fittings for my liking.
