Hi Shannon, Here is tip for the PEX-B rings. Use a pliers on the ring before you crimp it so it doesn't move all over the place on you.

[@robertadriver6931]

I used to work in construction & when Pex first came on the market & plumbers began using it, there were those that claimed the strength of the material would not hold up to climates with extreme temperature fluctuations. My guess is that there might have been some issues when it first came on the market, whether it was manufacturing problems or incorrect installation methods, regardless it seems that this product has definitely become a mainstay in the building industry.

I built myself a nice manifold to control all of my water fixtures independently in case of a leak or whenever I need to replace or repair any without having to cut off the main and disruptions to the rest of the house. I almost spent as much money as the quoted price to replicate what I had beforehand, with the manifold. I learned a lot and don’t regret my decision to do it myself.

I replaced all the copper pipe in my house using Pex B and the pinch type rings. Initially rented a crimp tool from local hardware store for a repair, then went ahead and got the pinch tool for about $30 at the time, maybe 15 years ago. I haven't had any complaints with the flow - not sure what the measurable amount would be. Anyway, the route I went is very easy for DIY. More flexibility, like with the A, would've been great while doing the various renos on the house, but got it done with minimal hassle on my part. Only trouble I had was 1 bad bag of pinch rings, which snapped when tensioning.

[@SteveLouzon]

I question the restriction claim. Every fixture in your house has a water saver restricter in it anyway. Maybe up size going to your outside spigots will help there?

[@harrisb43]

The restrictors at the fixtures have been designed to meet assumptions about the volume of water that would have to pass through that restrictor. There could be a dozen or more connections between your pressure reducing valve and the end fixture, and each of these will very definitely act like a low-value flow restrictor and, in total, cause an exagerated restriction effect at the fixture.

I hooked up a new water softener I guess it's been over 20 years ago now and I grabbed a roll of PEX and they had external compression fittings that I used. Never had one bit of trouble with them but I never see those anymore. I guess my point being that there's no restriction with the type of fittings I used.

[@bdog0720]

A couple of things that where not mentioned was PEX B you will need to recalibrate those crimping tools. The rings are forced closed and the force to do that is also applied to the tool. So the tool is gradually closing less and less when doing large jobs. There is a measuring tool with PEX B. It measures the crimped ring diameter after you crimp it with the tool. It’s called a “go no go” gauge. This gauge will tell you if your crimping tool needs to be recalibrated. PEX A fittings are not to be used with PEX B fittings. PEX A fittings have a barbed connection which grabs the inner wall of the pipe as it shrinks back down to its original diameter. It acts like a fishing hook. PEX B has a ribbed connection that only works with crimped rings.

[@tinysand3517]

thank you, very clear explanation

[@jimmypautz]

This isn't as much of a concern with the stainless cinch clamps.

[@GeoffreyMorrison-xh2eo]

According to someone else here, interchanging methods and fittings is more common now. At least one mfr., concerning Pex B, indicates that their tools don't need calibration. Nonetheless, thank you for your expertise here--your methods may prove better, still: We're getting closer to the truth.

[@bdog0720]

@@GeoffreyMorrison-xh2eo We shouldn’t rely on what “someone else here” says. This is a copy and past from the manufacture of the crimping tool. Go/No-Go Gauge 1. Slide the correct slot on the gauge around the crimped ring. 2. If the ring does not fit into the "Go" slot at all, but fits into the "No-Go" slot, then the crimp is not correct. Remove the incorrectly crimped ring from the PEX pipe, adjust the crimping force on the tool and repeat the crimping process. 3. If the ring slides into the slot and stops in the "Go" range at least at one point, then the crimp is good. The ring will not fit the go range all the way around it. Please check every ring with the Go/No-Go Gauge after crimping to ensure a proper connection. Along with a diagram of the tool: How to adjust the crimp diameter: All Apollo PEX Tools are pre- Adjustment Dial calibrated for 10,000 crimps. After repeated use, the crimp tool may need to be adjusted to produce a proper crimp result. 1. Note the number that the adjustment dial is currently set at. 2. Pop off the C-Clip that is aligned with the adjustment dial with a small tool, such as a flathead screwdriver. 3. Slide the hexagonal adjustment dial head out approximately 1/4". 4. Rotate the back pin until the line on the adjustment dial head points to the next highest number on the tool body. 5. Push the adjustment dial head back into position and return the C-Clip to its original position. We should only pass on information from the manufacture, not opinion. That is the only truth.

[@jasonk4685]

This was a huge help. I’m looking at installing a recirculation line and I was having trouble deciphering the differences. This made it super clear!

[@bdog0720]

Recirculating pumps do have a considerable drawback. There are fine solids in the water coming into your home. The pump is always circulating your hot water. So with that it’s wearing down the inner walls of any type of pipe you have weather it’s PEX, copper, pvc, etc. Non circulating hot water only goes one way and only when you open the hot water handle at the faucet or shower. So it’s not wearing down your pipes as much as a recirculating pump. Use a whole home water softener and purifier to clean the water coming into your home. This helps but there is nothing that will prevent inner pipe erosion. Ask your plumber for best application in your area and look it up online just to make sure. Good luck.

[@thenexthobby]

Zurn tubing can be used with either cold expansion or with crimps. Conforming to ASTM F1960 is what allows this type B tube to be expanded, since the expansion method is what F1960 describes. A vs B only describes how the tube is extruded, not the connection method.

I re-plumbed my house with Pex-A. Spend the money and buy the Milwaukee expansion tool, the manual one is too much of a hassle. One disadvantage to Pex A, your fittings can't much closer than about 3". The problem... when you put the expansion tool in the pipe on the second fitting, if too close to the first, it will jam and freeze inside the first fitting. I found out the hard way.

[@lucash1980]

That 3" minimum between fittings in Pex-A can be a big problem in some tight spots.

[@JasonECI]

Your explanation is always the best to the point material!!! I've used crimp rings and cinch rings for pex A for my whole house pipes update and worked fine for the last 11 years, but I assume the fittings were for pex A pipes because they look a lot different from the pex B fitting you show in the video. When I did that, a plumber told me that crimp ring is much more reliable than cinch ring, I used both, while they worked the same under 80 PSI with no problem, the cinch tool is a lot more friendly especially in tight areas.

there is a video that shows that REGULAR Pex A and Pex B transitions can be made with common Pex A and Pex B fittings... though the manufacturer would not warranty that installation. Meaning, if you already have Pex B in your house, and you want to replace some of that line with Pex A, you can use regular transition fittings but would void any warranty. There are official transition fittings but those are extremely pricey.

Just curious if you noticed any pressure difference if you used 1/2" . I thought if you decreased the diameter you increased the pressure. Your thoughts please.

[@ravenstarver1360]

@@dirkhagar2399 In a home system the pressure stays the same, in a linear flow system decreasing the diameter might increase pressure, like in running water through a dam. At home with all the taps turned off, the 1/2" pipes are at the same psi as the 1" pipes The larger the pipe the more flow it can handle without a noticeable drop in pressure, beyond that flow the psi will drop and flow will drop. More restriction just can't replace the water as fast to keep up. There are good videos on required diameter of plumbing for a given number of fixtures running off of the line.

Great learning video. I want to use Pex for replacement plumbing in my RV. Type B seems easy, but I thinking of going with type A. I like the line flexibility and less joint restriction.

Just to clear up, some things. Reducing flow causes pressure to rise at the end of the reduction, not entirely a bad thing especially at the end of the lines. Second is that you dont want too much pressure in your plumbing, its recommended to install a pressure regulator on your water heater to below 50 psi.

any comments on expandable PEX B that is now available please

[@HouseImprovements]

I have not used it but I'm sure it is fine.

[@michaelrogers4285]

Thank you Shannon

[@chippydog2]

How can you tell the difference between Pex A and Pex B ? Can you tell by the writing on the tubing?

[@HouseImprovements]

Mainly the fittings but most will say Pex A or Pex b on the pipe.

[@chippydog2]

@@HouseImprovements I thought so too I know it’s Sioux chief but nothing on A or B

[@lorenzocriscuolo7869]

Hi Shannon, if you’re suggesting oversizing pex B to (from 1/2” to 3/4”) , won’t you still have to reduce to 3/8” at the stop valves? Stop valves are normally 1/2-3/8, unless there are 3/4-3/8, which I have not seen. Thanks.

[@lorenzocriscuolo7869]

Termination at the fixtures I meant,obviously (under kitchen sink,vanity,toilet,etc).

[@ST-0311]

@@lorenzocriscuolo7869 You are correct. One would have to reduce to 1/2-in where the pipe terminates before attaching to the supply valve. However, you won't have the multiple restriction points in your main line if you run 3/4-in. The only restriction comes at the supply valve, which reducing to 3/8-in is going to cause regardless of size of your lines. Actuality, with 1/2-in fittings constricting to roughly the equivalent of 3/8-in you're basically reducing to directly from 3/4-in to 3/8-in.

[@HouseImprovements]

Yes you are correct.

[@HouseImprovements]

MagiusUSA has the answer for you.

[@billsmith9249]

those sizes are common here in the USA.

[@nivekgad]

If using pex B with shark bite fittings, would that be as restrictive for water pressure as your fittings?

[@HouseImprovements]

that would be less restrictive than the standard PexB fitting I showed here.

Hi, I don't have the expansion tool but i have Pex A. Can I use the ring and crimping tool on Pex A? Thanks

[@HouseImprovements]

No, you can not

[@mark.r8900]

Thank you for your reply. So even if I use a pex B fitting into a pex A pipe and crimping it with a cooper ring it's no good?

[@jmcrypto1555]

What if I can't identify my pex? Should I take a piece into a supplyhouse to identify for me? If I suspect pex, a pex A fitting would not slide into the pipe, right?

[@HouseImprovements]

If you can see existing fittings and how they are fastened that should tell you easy enough but other wise Pex A fitting should not slide into either Pex A or Pex B without expanding the pipe A Pex B fitting will slide into either pipe .

[@jmcrypto1555]

Thanks! Took a peak in attic and couldn't see much but did see Zurn pex marking. This means it's expansion rated right?

[@KrazyKajun602]

Which is better to use underground for longevity?

[@HouseImprovements]

either one is fine really. If you use PexB make sure to use clamps made for underground use.

[@haiderhannan8038]

Why not have a compression joint with a olive ring, like we have in England?

[@davidson2004fatboy]

GREAT JOB !!! IF MONEY WAS NOT an ISSUE. WHAT WOULD YOU USE IN YOUR HOME ? THANKS

PexA

@@HouseImprovements obviously your not in a cold climate! They say Pex A is crack or burst prone. I guess normal climate conditions you could use what you want My climate sometimes reaches-40 f and I’m using hydronic floor heat under my basement slab .

[@watchitrunning]

Just one thing to add. If you want to undo PEX A connection don't use knife to cut the pipe off the fitting. You can leave a scratch on it that is prone to leaks. Use construction fan instead. Wait until you pipe turn clear and use pliers to get the pipe off the fitting.

[@ohger1]

Cut off the expansion ring and then **score** the PEX A pipe (not cutting through it). The heat gun will then allow slipping the pipe off the fitting without damaging the fitting.

[@chippydog2]

@@watchitrunning construction fan ? I don’t follow!

[@consumersgasman8376]

fitting restriction not an issue, only fixture where size is an issue is the shower, you could pipe a house with 3/8 pex and not see any difference in flow, first pex on the market was type A , it required a very expensive expansion tool for installation with the shrink rings.

[@spartaeus]

Everything I've read on the internet says you can use cinch rings for type A pex. You didn't mention that.

[@HouseImprovements]

I suppose maybe you could but you can not get the fittings inside the pipe without expanding the pipe first so what not just install the proper expansion rings?

[@spartaeus]

@@HouseImprovements Type A pex has the same inside diameter as type B pex. Type A pex slips right over the brass type B fittings. No expander tool needed. And the brass fittings and cinch rings are very inexpensive.

[@micahjones7188]

Consider The zurn Or Sioux chief power pex b. I am converting to cold expansion pex b for plumbing business.
