Why did you have to do it in pex rather than copper?

@@integr8er66 cheaper

OMG, PEX tubing in my basement has been exposed to light for ten years… is it sensitive to DEL?

Poor contractor work, or the cheapest price? 😂

🤗🤗🤗

But if the fitting is copper, would it not be best to have a crimp ring having the same thermal expansion coefficient?

@@somaday2595 Good question, but no. The thermal expansion coefficient of PEX is 5x greater than that of copper. So, as the copper fitting expands when heated, the PEX is trying to expand AWAY from it 5x faster. The crimp ring constrains it, so long as the hoop forces stretching it don't reach the copper's yield point. If the crimp ring ever exceeds its elastic limit, it is game over. And that is where stainless beats copper by far. The stainless used in Oetiker clamps is quiet soft by spring steel standards, yet it still has at least a 50% greater yield strength than copper, which allows the "ear" to be formed by cinching. That ear acts as a spring, maintaining near constant hoop tension across a varying range of circumferences, making the stainless clamp kind of impervious to crimper calibration issues that haunt the crimp system. Still, when applied correctly, all of these systems are known to hold beyond the burst strength of the PEX, making arguments about what's best kind of moot.

@@robertlitman2661 Yield strength of the ring material was not in question but rather, the ring compression force on the PE. If the SS expands less than the Cu, the compression force would be stronger with the SS ring. Within a few thermal cycles, the seal with the SS when cold would be a less tight than the Cu ring. The PE will not creep back once it has flowed under compression of the ring.

@@somaday2595 That's why we use PEX and not plain PE. The cross linking is what stops creep and makes the whole system work. That creep is also why PE icemaker lines are a time-bomb, and I have concerns that PERT will turn into a PB fiasco eventually.

Thank you soooo much Mark!!

Niceeee, thanks!!!! 💎💎💎

Yes.... I have fond memories of ratchetting crimpers for RF coaxial cables - Suhner, Mmmmmmm... :-)

That's all I use these days.

You also save time not needing to check with a gauge.

Hahahaha IT WORKED!!!! Thanks Dash!!!!!!!

Yep. In the southwest and we stub out with pex for all fixtures and in 15 years have never had a single problem.

Im new to Pex and about to do something in my utility closet out to the spicket on the front of my house. Why is it an issue to use Pex in a room with a water heater? Its not sunlight?

That's because the home owner doesn't know you piped the place and how to get in touch with you. Copper is king on stubs. @@spacecruisers

But I thought there's a shortage of labor lol. That's what all these companies say

😂😂😂

🤜🤛😎😎😎

Same here. As a home diy’er I didn’t want to invest so much on crimping tools that I’ll seldom use when a single chinch tool will do both 1/2” and 3”4” and can access areas that the crimping tool can’t! Plus I can use a chinch tool with one hand. Cost, access, one handed use...all positives for chinching over crimping.

You can also cut off the cinch clamps with much less chance of damaging the fitting. Most of the time, you can use pliers to pull the ring side away from the locking teeth, and it will pop open. However, I generally don't reuse fittings. It's not worth the risk when they only cost $1-$2 each, even for the brass ones.

Until they fail because of the uneven tension on the rings.

Yeah, it degrades and can eventually leak 👌

Thank you so much Roger, I try hard to make them entertaining and informative at the same time :)

Get rid of the rats!!

Try using conduct that's what recommend for in ground pex that's been chew into by moles or gofhers..pvc pipe for conduct

If you are starting at the water supply and working towards fixtures,avoid going from smaller to bigger. So if you are at the shower and working towards your water supply source,it should only get bigger and bigger pipe diameter as you work towards the main water shut off valve. If not not only can you have issues with water pressure,but you could end up getting noisy pipes when water is running. I seen a house where anytime you used the bathroom sink,the whole house had a loud squealing sound. All because they had a small diameter,large diameter and small again. Hope this helps with what you were asking.

Good advise! 🙏

What about pex a sharkbite

Glad it helped!!

Glad to help L J, thanks!

👍😇👍

Yes indeed!

Have you tried using a pressure washer? kzfaq.info/get/bejne/Y7OBgdB73NjbfI0.html

We would always up size the pex in certain homes. Instead of 3/4" trunks like we would do in copper, we would do a 1" trunk, with 3/4" fixture branches. But now, I run uponor for the reasons you mentioned. I prefer the uponor now. I got mechanical Apollo Expansion tool at Menards for about the same price

WTF?! There's a 90 bracket shortage too?

@@nomansarker5556 yeah, according to the uponor company, their factory that makes them had a covid outbreak. Causing the shortage.

First off, thank you so much. I prefer crimping in general, never had any experience with the SS cinch rings as you mentioned, but a lot of people love them so I guess it's all up to you. As for plastic of brass, I don't have a preference, as long as the brass fittings are DRZ (dezinc resistant) you are good to go!

I had to redo some plumbing for my bathroom renos and planned on reusing the brass fittings. They had patches of corrosion on them, inside and out. Still trying to figure how the corrosion spots started on the outside of them when the water isn’t supposed to be there. Not some of them, all of them. My house is only 20 years old. I opted for the stainless cinch rings and plastic fittings. The cinch rings are easier to install, you can see them while you’re cinching them to make sure they’re in the right place and straight and the cinching tool needs far less room to use.

Prices may have changed but for the small fittings there wasn't much of a difference (bought online), although I used brass because the area had a chance to freeze. For bigger fittings like manifolds it can be a much bigger. For matching old pipe to new, first making certain one has all the needed fittings. Attach and tighten those first before attaching PEX since PEX isn't suppose to like twisting action once crimped.

🤗

My pleasure!!!

It'll most likely damage the pipe 🙏

It will never be over crimped unless you adjusted your crimper wrong to begin with. The jaws only loosen with time and lose tension

Glad it helped!!!

got a question hopefully you can answer. Leaking flapper. Replaced (tried 2 different ones). Still leaks. I adjusted the chain setting to just about everything possible from fairly tight to really loose. From what I can tell the flush handle pulls the flapper sideways sometimes (not always). When it goes sideways it doesn't fully re-seat, and then I get "ghost flushes" once in a while. This is the first time I've had this problem - replaced flappers several times previously.

Might need to Macgyver something.

@@WJHandyDad My old flapper had a mini-weight above it.

When properly calibrated go fits and no go doesn't. That's pretty much where the naming convention came from. The goal is to have go fit and no go not, anything else fails the test and requires calibration.

@@CraigSanders04 thanks!

Well done!!!

I don't think it's any more expensive than any other pex. Maybe the tool, but you can get an Apollo Expansion tool for 1/2" and 3/4" for under $150. I believe a power tool is under $300.

@@ericlewandowskivlogs Good point. I was only considering the Milwaukee 1/2" to 1" power expander I used for HVAC. The only thing I didn't like about working with PEX was that 1" and bigger roles of PEX can be a real pain to straight, especially in the winter .

Thanks for watching!!!

🤗🤗🤗

Yeyyyyy!!!!

You bet, thanks José!!

Yep

Are you talking about shark bite fittings? If so, one day you’re probably going to wish you hadn’t done that. They’re known to leak after a while. Sometimes after a few months, sometimes a few years down the road. Check out Roger Wakefield’s channel. He’s talked about it a lot and even did some tests to the point of failure. It doesn’t take much pressure to pop off a shark bite whereas the crimp fittings don’t come apart.

🤗🤗🤗

Glad it was helpful!!!

100%

Indeed! I've watched other videos which enumerated the pros & cons of PEX, but none of them mentioned anything about UV resistance. I wonder if the manufacturers can do something to make it UV resistant.

🙏🙏🙏

🙏🙏🙏

i enjoy sweating but the investment in pex tools is far less than the cost of time and material when using copper.

One day you’ll need to pull some plumbing lines to replace old corroded pipes in a second story bathroom. I have an upcoming project where PEX is the obvious choice due to constraints on where I’ll be able to pen up the walls.

I agree. However, I have the power tool for Uponor. Some people insist. It is FAST. Cheating, somehow. Huh?

@@stephenholland6328 There is always soft copper piping.
