I have been plumbing as little as possible for 40 years.Plumbing is my least favorite job to do,but after 40 years you learn a lot and I know 85% of this already.Your approach to-teaching is amazing and I enjoyed watching the video from start to finish.Thank you sir.

just watched a pex video from a big shot Texas builder, your video is far better in all respects. thank you.

[@anasalamri8320]

I googled pex pipes as it was rarely used here in Saudi Arabia and it's new to me. I'm glad I found this video. Even though I did not need to see all of it but I did, your stream of thought and explanation is perfect. Thanks for taking the time to make this.

[@Chris-xo2rq]

Just had a -18F night here and my copper pipes burst in SEVEN places... one completely in half at a joint. Going to replacing it all with PEX-A

[@nothankyou5524]

Use the correct material and you'll PROBABLY have no issues. Eventually, under proper circumstances, residential products tend to have failure points. Take a look at some of the hospital grade stuff. Anyway, depending on where you are, "heat" is your friend. I'm in the South now. Nobody who asks me about this stuff believes pipes here burst. Until there's or someone they know has a burst pipe. You hope for the best, but you plan for the worst, and hope you never need it. Waste of money? If so, why buy jumper cables? Best wishes & best of luck. You sound like a pro in the making. I instruct on jobsites up and coming Techs. You're miles ahead, already. Trust me.

Boy, I would have been the star of the class had you been my teacher!! Awesome education you just provided. Thank you so much

[@ConstructionEd]

Wow, thanks!

[@SoniaBDorsey]

Thank you for your content. A few yea ago, in Texas, we were slammed with a horrible winter. A property of mine in Louisiana suffered plumbing damages that required the entire home to be replaced. I was taken clearly by surprise when I went to check on it. Weeks would go by before I could address it. Visiting a mom & pop hardware store, one of the workers suggests I consider PEX. I only knew PVC and purple cement/glue. He convinced me that it was worth researching if replacement was needed. I invested in the tools and materials and did the job myself. First time doing this. My dad was too ill to assist at the time, but he beamed when I told him, “Dad, it’s finished, it’s done.” If you are reading this, “You can do this!” Two bathrooms, kitchen, and laundry room….done by yours truly! There’s a tool that takes the manual labor needed out of the squeezing required to get the ring to crimp close. Being in tight spots also makes getting a good grasp on the tool challenging, but it’s very doable.

[@barbvinal]

My plumbing skills have always involved PVC, but they were clumsy at best. Now that I have a rental property completely plumbed in PEX, this video definitely upped my game! Thank you so much!

This is a VERY well put together video!! Mr. Carswell is very easy to understand, and is very explanatory about the different types of pex pipe and fittings. He takes his time to cover the different uses, advantages and how they work. There are also close ups of the different fittings. He talks in a very quiet and slow manner which is easy to follow. I have a tool box of fittings, push connectors and a roll of pex pipe for my own use. After watching this video, my knowledge has been upgraded. Very well done and a lot of information.

[@tomwadsworth5768]

When using the push to connect fittings, especially on copper, make sure to deburr the end. The o-ring seal inside can be damaged causing a leak. I would also recommend extra care on any pipe material. Even a small piece of plastic getting under the o-ring can cause a leak. These are very reliable when carefully installed. They are very well made and even have an inner support tube to help hold alignment.

[@ConstructionEd]

Great additional information - thanks for responding. This fitting is all about that inner O ring!

[@XSR_RUGGER]

They're also susceptible to damage from cold temperatures. We use them when we need to but we don't put them in walls because sometimes they will develop a slow leak after a few months due to damage to the o ring or improper seating. You're also supposed to remove the pipe support on hard pipes like copper and cpvc.

[@deliveryguy7402]

The push to connect fittings are good but usually are used for a quick fix. I will replace them with the correct plumbing type when I have more time.

[@oliver-ec9mv]

When using a push to connect PEX fiting inside walls does anybody know if this meets code

[@robertjackson7590]

@@oliver-ec9mv I've looked for that answer as well and the general consensus is don't use them in a wall, only open areas. I've seen it used on air systems in an open environment as well and it works. Like Deliveryguy's above post don't trust it. Something else I saw as a concern is the plastic elbows on Hot water will heat cycle, get brittle and could break if they have any awkward side loads in say 5 years.

[@adelesexton5975]

The biggest mistake people make when switching from copper to PEX is using the same number size such as 1/2" PEX to replace 1/2" copper. 1/2" PEX = 3/8" copper and 3/4" PEX = 1/2" copper. This is due to the thicker wall thickness in PEX. Small internal diameter equals less water flow.

[@mrgarner11]

Good to know. Thank you.

[@jeffriley2502]

The fittings are the bigger reduction do to clamping methods PEX A vs Pex B. Pex A is more true to size because pipe is expanded to go over larger fittings.

[@mrgarner11]

@@jeffriley2502 excellent advice. Thanks. I am a newbie to this kind of plumbing, but it strikes me as odd that you can clamp pex B over top of a plastic fitting and not split the fitting.

[@jeffriley2502]

@@mrgarner11 I personally stick to the brass fittings, cost is more, however I believe it to be better and safer overall installation. I've been researching this for a while and starting a remodeling project. It can be confusing with all the different Pex/Plastic pipe variables out there. Sizing differences make it more complicated.

Ball valves are not throttling valves. They should only be used as an on/off valve. You can use a B/V to throttle for a short period of time, But the teflon seal can wear and when it is time to stop the flow, it may not. A globe valve, a needle valve, a butterfly valve are all better choices.

[@Trahloc]

No mentioning of being careful to not confuse expandable and insert fittings where pex-a is always expandable and pex-b is commonly insert only (zurn being the exception to my knowledge). Expendables are full bore as the pex-a/zurn pipe is expanded so they don't obstruct flow while pex-b inserts restrict flow as they fit inside the pex-b pipe. It's a very important distinction and the reason I believe Pex-A has the reputation for being 'leaky' when it's really this critical piece of missing information.

[@jackt6112]

I did not know that but I decided on B. Plumbers seem to be using A, and there is a video of one vs. the other. In it he says the tool for B is $150 and the one for A is $250. That's WAY off. Try $32 for the B crimper, cutter, 20 1/2" crimps and 10 3/4" crimps. The tool for A is more like $475. The PEX A tubing seems better, and more expensive, and when they connect the two together they, they simply crimp it onto a B fitting. At first I was going to use A tubing with B fittings but decided against that too. While A can recover from a kink, what are the chances of that actually happening after install, and if you use a bend guide support, it won't happen at all. Yes, there is a restriction at every fitting with B, but would the difference even be detectable in userland? Faucets and showers have flow restrictors that limit it anyway so I doubt it. There is even a screen on the washer inlets. About the only place it is unrestricted is the hose bibs and those are usually fed by 3/4" main and 1/2" through the wall and even sprinklers don't kick out that much unless you are using it for underground sprinkling in which case you wouldn't go through the wall 1/2".

[@Trahloc]

@@jackt6112 There are various tools for A and B, if you want to compare the cheapest A it's around 60-80 but it's manual, I'd rather spend the 400-450 you mention on the dewalt battery one. "A tubing with B fittings" - yeah that'd be a waste, the whole point of A is the full flow fittings. The crimp recovery is just handy bonus. As for the restriction being detectable. I personally feel it *has* to be detectable because I grew up in a house with copper full flow fittings and the pressure was fine with multiple bathrooms in use where as my post 2000 build homes have terrible water pressure even though the water hoses which break off early in the water lines for both post 2000 houses are about the same pressure. I can only blame the fittings or multiple houses have had really really bad plumbing designers vs the 1960s.

[@jackt6112]

@@Trahloc Actually I was comparing it to the Milwaukee but it seems the DeWalt is priced similarly. From what I've seen on KZbin and online, unlike PEX B, doing PEX A with a manual tool is considered operator cruelty. On the flow restrictions, I have nothing to compare it to. Galvanized 1/2" is .622", copper is .527", while 1/2" PEX is 0.485". The dimensions were arrived to to duplicate tested to have the same average flow over time in a plumbing system as galvanized of the same size so there is no difference for design purposes between galvanized, copper, or PEX. However, we know, PEX A doesn't have the diameter restriction at the fittings so that begs the question, which PEX established the ID? My guess would be PEX A since A comes before B, and none of the others have restrictions at the fittings. Both PEXs are the same ID so PEX A should flow better to some extent, so that would mean that there is no valid design standard for PEX B. PEX B is an easier install and has the better track record for not developing leaks over time. However, PEX A is approved, so it cannot be that bad. Black Polyethylene Tubing as used in underground sprinkling tubing and gas lines has a .600" ID so it does compensate for barb fittings. I'll have to research to see if there is a de facto adjustment for PEX B that can be used to ensure a PEX B system has similar performance to the others.

[@ConstructionEd]

Great conversation going on - really great to see. We just purchased the Milwaukee PEX A expander and will be doing a video about PEX A in the coming weeks. My two cents on the flow restriction of B - it is a real thing. I redid my house from copper to PEX B using a distribution manifold and a clean run for each line. I noticed a measurable flow reduction. I will measure it as part of our next video - or an additional mini lesson as part of the series.

[@jackt6112]

This will make makes a sense out of the experiences of both Trahloc and TEACH Construction Community Education, as well as saved me from downgrading my current 72-year-old galvanized system to a new lower performing new system. There is a Williams Heating and Plumbing KZbin video "How to Size Your Water Lines (PEX & Copper)" that shows how to size using the 2018 Uniform Plumbing Code where he used with the 75% method. He says in the video though that it is for galvanized also, which indicated to me that it might be based on the Schedule 40 standard, so I decided to check. I didn't find that, but I did find "2021 Uniform Plumbing Code" "Appendix A Recommended Rules for Sizing the Water Supply System" shows its roots are based on Schedule 40. There is a lot of useful information in it based on water pressure, length, and even disambiguates between threaded and non-threaded fitting adjustments (E.G. a 90 degree fitting is the same as adding 2' to the pipe etc.) that are not included in the video. It also gives the average flow rates of many components such as kitchen sink, showers, etc. According to the video, there are no differences that need to be considered between galvanized, copper, CPVC, and PEX. Moreover the recommendation adjustment for PEX B fittings is if you are close to the limit on the calculated size required and there are quite a few fittings, then upsize it. This might work for plumbers. However, I see problems with what was presented in the video as well as the Uniform Plumbing Code if your expectation is match the performance of another technology. Steel and CPVC are Schedule 40. Copper and PEX are not, and their inside diameters are substantially smaller. PEX is not even mentioned in the "2021 Uniform Plumbing Code" "Appendix A Recommended Rules for Sizing the Water Supply System", so one cannot say that the reference cited in the video supports the method demonstrated. One would need to find the PEX-specific information to adjust the otherwise useful method shown. Looking at other references, flow rates have a lot less to do with surface roughness than diameter. My guess is the reason they use 100' as a basis is because at 50' it is hardly worth mentioning. So let's look at some numbers. Pipe IDs. - Galvanized 1/2" ID is .622" (Schedule 40 spec. was speced oversize for steel pipes to compensate for average flow restrictions of fittings) - CPVC 1/2" ID is .622" (Schedule 40) - Copper M 1/2" ID is 0.569" - PEX 1/2" ID is .485" - PEX 5/8" ID is .584" - Schedule 40 3/4" is .824 - 3/4" Copper M is 00.811 - PEX 3/4" ID is .681" - Schedule 40 1" ID is 1.049 - Copper M 1" is 1.055 - PEX 1" ID is 0.875" Flow rates from a Supply Resources (The min is based on 2' per second and the max on 4' per second.) - 1/2" Schedule 40 calculated max 3.841 - 1/2" Copper min 1.6 max 3.2 - 1/2" PEX min 1.2 max 2.3 - 5/8" PEX min 1.7 max 3.3 - 3/4" Copper min 3.2 max 6.5 - 3/4" PEX min 2.3 max 4.6 - 1" PEX min 3.8 max 7.5 What this indicates is if you want 1/2" copper performance, you need to go with 5/8" PEX. If you have galvanized or CPVC, it is Schedule 40 which is altogether different again. So let's do a rough estimation of what it would be for 1/2" galvanized and CPVC. - 1/2" PEX has an area of 0.18475 with a flow rate of 2.3 gpm - Copper has an area of 0.2543 with a flow rate of 3.2 gpm. - The area difference is .0.06955 with a flow rate difference of .9 gpm - If we divide 0.06955 by 9, it will yields 0.007727777777778 per .1 gpm - Schedule 40 1/2" based on it's .622" diameter has an area of 0.30386 - The difference in area between Schedule 40 and copper is 0.04956 - If we divide that by 0.007727777777778 we get 6.413227893601541 tenths of a gallon more than copper. - From this rough calculation, Schedule 40 1/2" flows 3.2(copper) + .641(for dia dif) = 3.841 gpm for 1/2" Schedule 40, but is actually a little more than that because the circumference doesn't increase linearly with the area. So we will now enter that into the table above. PS: You might want to check my math. I found an error in an inside diameter, corrected it, and recalculated, so you may find something out of sync. This is all very useful but what about the difference between PEX A and PEX B? That information was a little more difficult to find, but I did. "PEX manufacturers state that PEX uses about 30 percent fewer fittings than CPVC in a typical installation, but that doesn’t come close to offsetting the higher pressure drops that occur with PEX pipes and fittings. Compared to a PEX system with 30% fewer fittings, CPVC (which is Schedule 40, achieves a 74-83% reduction in equivalent length caused by fittings. The reality is that even PEX expansion fittings, which are sometimes referred to as "full-flow", restrict flow rates. In fact, the difference in the internal diameter between a CPVC fitting (schedule 40) and an expansion PEX fitting is greater (27%) than the difference between an expansion PEX fitting and a PEX plastic body crimped fitting (22%)." Thus, this states there is a cost for PEX A due to its diameter plus another 22% for PEX B plastic barb fittings. The difference in flow comes out about what we calculated based on diameter. However, this used 8 feet per second rather than 4 feet per second, which increases the difference, but highlights the cost PEX A is significant and PEX B adds a lot to that. Analysis: - To barely maintain 1/2" copper performance one would have to go to 5/8" PEX and it would still be well under 1/2" schedule 40. 3/4 copper or Schedule 40 would have to be replaced by 1" PEX, and that is before the penalties of PEX B fittings.. - Schedule 40 is over engineered for the average flow restrictions from fittings. Copper and PEX use a Fisherman's Scale to measure size which explains the lower performance people are seeing with PEX. - Using the Uniform Plumbing Code book for sizing your system won't save you because its based on Schedule 40 standard. The plumber in the video used 75% of max. capacity for design which won't even save you because simply copper to PEX puts you at 71%, 60% of the Schedule 40 used for the calculation, and that's before any PEX B fitting penalties. - Reading online I learned that PEX B almost never leaks while manual tools used for PEX-A very often end up leaking and you need to spend $400 to $500 to get a reliable installation. - Before this, I hadn't even considered CPVC since I don't see it getting much attention like copper or PEX nor did I expect to gain respect for galvanized, even though I would use galvanized today. *I found it interesting that copper M in 1" is very slightly larger than Schedule 40 1" which was quite the opposite with the smaller sizes. I'll answer this question before it gets asked. Question: Have you seen inside of your 72 year old galvanized pipes? Answer: Yes, and they are wide open. A lot of water flows through them which keeps them clear. I have no pressure problems and was simply concerned with their age. I have worked on a house where they didn't use the downstairs bathroom and there was only an 1/8" hole remaining in a pipe and another that looked like stalactites on the inside of a cave. However, those line seen very little activity.

Very much explanation you add the skills to many

[@walterhynson2898]

ok you are a great teacher but my question is if this new stuff (pex) is so easy and so much cheaper than why do the plumers have to charge so much to install(new home ) or repair or install something.??

[@ConstructionEd]

When you hire a plumber you are paying for the skills, expertise, all their tools, licensing, insurance, code compliance, and warranty. In my personal opinion, Skilled Trades should charge more than they do now and if we as homeowner's want to save money - we do the work ourselves. Good trade work is not cheap.

[@therookie5714]

@@ConstructionEd I agree, plumbers and skilled tradesmen should be paid more

Been doing my own plumbing for years. Lots of tools, pipe, joints/connections, glues/solder for galvanized, copper, pvc, etc. Recently a pipe and valve started leaking in my recently deceased mother's house. Unbenounced to me the house had been replumbed with PEX a few years ago but I can't repair it as I don't have and can't afford to buy the special pipe, valve, fittings and tools needed to make the repair and nothing I have works with PEX. Trying now to contact a plumber that has the proper tools, parts and knowledge to make the repair without it costing me a large part of my SSI monthly income.

[@ConstructionEd]

Plumbing and plumbing tools can be very expensive

[@jimdudder7450]

@@ConstructionEd > Think it would have been less expensive if I had bought the tools and parts and attempted the repair myself. Wont go into the whole thing but felt kind of violated when presented with a bill for $500+ (almost half my monthly income) from a plumber I was told was good, reliable and "inexpensive". He was here for about an hour and replaced a section of pipe, a flow control valve and tested the system.

[@FORTRAN4ever]

Very instructional. I have PEX plumbing that has sprung pinhole leaks for no reason that I can gather. All on the hot water line. Three are on a short line between the water connection and wall. Another happened on the hot water supply behind the bathtub in the main bathroom. I cut a large rectangular hole at that spot in the bedroom adjoining the bathroom. In addition, I had to install a new cutoff valve to replace a broken one in the cabinet below the kitchen sink. Very cramped space so I used a PEX coupler with a threaded end in the supply line and its threaded mate one the new cutoff valve. That way all I have t I do if the new valve fails in the future, all I have to do is screw off the valve at the connection with the supply line where cutting off the valve and installing a new one is much easier. In all cases, I made the repairs myself using pinch clamps. I got also got a Ryobi (operated with a rechargable battery) clamp crimper as well as a manual on. Also got both a ring removal tool and crimp clamp removal tool for both existing ring clamps and newly installed pinch clamps, respectively. I haven some extra tools and supplies. Considering the money saved on calling a plumber for every leak, the tools paid for themselves. One feature I like about pinch crimps is that they are easy to remove with the removal tool.

[@ConstructionEd]

Great work and I hope our video helped.

[@tinman1955]

Springing leaks for no apparent reason does not inspire confidence in PEX. Think you got some defective pipe? Had it been installed for a long time? What brand?

[@michaelcurley989]

I see this way too often in water restoration, pex sucks

[@tomwadsworth5768]

@@michaelcurley989 I have seen some really low quality fittings. The effective orifice is reduced causing pressure drops. I do like the push-ins. No crimper needed and great in tight spaces.

Great video! Copper is time tested to last at least 50 yesrs. Pex piping systems haven't been in use long enough to say how long they will last. They sure are easier to install for DIY .

[@s-w]

Rodents can also eat through the pex as well. If you can afford it, copper is better for sure.

[@ConstructionEd]

that can be an issue.

[@ConstructionEd]

Copper still has its place. And many think that PEX is just crap and should not be used.

I am glad you are not afraid of the plastic fittings - but if you can use the metal ones that is the direction I would personally go. We show the plastic versions as an option in this video because our main reason for producing these lesson videos are for our school partners. We add these videos to our Community Education channel about a year after they are used for our school/training program partners.

This was a lot of information, but well presented and has made a few things clearer ..

[@ConstructionEd]

Glad it helped. Based on how you spelled labour I am assuming you are not from the US - Make sure that your local code allows PEX - it is not permitted everywhere.
