Hello everyone. Been a while since I posted but was curious what you all think about the various Pex fittings and tools. Is there anything to stay away from that wont last for years and years?
I need to do a small re plumb of a few appliances but haven't had to deal with Pex directly myself so don't have the tools yet. --74.130.xxx.xxx

Stay away from shark bite fittings. They are good for a quick, temporary repair - but not durable for a long time. I've had two full houses of this stuff installed by pros, and no worries.
I recommend (recently used) the brass crimp rings. It is surprisingly easy to do, if you get the tools.
The Upnoor brand with the flared fitting is the "best" but also most expensive. I think the crimp rings are perfectly fine and much more affordable & easy.
Have fun! : ) --68.229.xxx.xxx

I am a California Licensed Plumbing Contractor and shy away from Pex and other "plastic" type piping. Why? Because before Pex there was Polyvinyl Chloride and others that either oxidized, failed and leaked -- or were found to be highly toxic to humans.. Not to say that PEX doesn't work or do it's job. But to open up a wall and simply put is PEX never made sense. Rats and other critters could take one bite and then you've got problems. A nail though the drywall could easily kill any Pex product. I use copper and I'm sticking with it. Done right, copper can last 60 years. --47.155.xx.xxx

Uponor is supposed to be the best as far as PEX is concerned. It uses a very pricey expansion tool as it uses expansion rings.
If you are using PEX just for a few appliances then I think you would be okay to use the crimp ring type, just be sure to buy the cut off tool in case you mess up and need to cut the ring off and save a fitting. You can do it yourself though as it is very easy and fast. Watch some Youtube videos.
Robert J is right as far as copper being the best option as it is also more rigid where you need that in some places. It is also proven to last for decades. However, it is time consuming and you need to know how to sweat copper and do it safely, especially in tight places. --73.120.xx.xxx

I've plumbed many a new bath with SharkBite and pex. As with any install-- if the installer is ignorant to how to install properly?????? it's on them.
Here's a classic example: blue poly pipe. Has anyone realty read the instructions? OF course not! People dig the trench lay the pipe and then back fill with trash from the house. Yea nails, tile pieces, wood, concrete--- rocks everything goes in the hole--- I've seen it a 1000 times. Then in 10 years, when everything settles, WHY is the line leaking? GEE I don't know?
Instructions say lay a sand layer 6 inches then put in poly then 6 to 10 inches more sand. Here's another thing that makes it fail. As the plumbers helper is unrolling the pipe he walks on it and crates that crushing effect on the line-- so in 15 years it springs a leak.
Shark bites-- have inserts for pipes -- people yank um out. Then they leave a gap as wide as the panama camel between the shark bite fitting and the pipe so it's barely biting into the line. --99.103.xxx.xxx

There are two types of pex which are A type and B type where the A type can be used in commercial applications along with there is restriction in the fittings where a 1/2" and 3/4" there the diameter is close to pex where more water flows. A type Uponor it is possible to install a pex sprinkler system where it is a easy install. A type pex is superior to B type pex where the big box stores only sell B type. The main cost is a special tool is the expansion tool which is around $400 upfront where the pex is expanded then a fitting is installed. A type pex is mainly sold at plumbing supply operations. A type pex bends more easily where fewer fittings are required. So before deciding view some videos on You Tube about A type and B type pex then see how the installation of a sprinkler system, plumbing supply and radiant floor heating works. A type pex installation is faster along less to go wrong. Fewer fittings less labour and less cost of fittings. Easy to bend where no fittings are required. Uponor will usually have representive who can explain the process. Uponor has a website where can see the special expansion tool when download a catalogue. --99.236.xxx.xxx

The pex is fine. You'll be ok. Even the shark bite stuff is fine. Just don't use it in an enclosed wall.
I've been using Propress a lot. I like it and you can get a generic crimp/press tool on amazon. But again, pex is fine, just not really rigid. So use strapping clamps, if its going to hold something up, like a valve, etc. --209.6.xxx.xx

For the purpose of this discussion there are 3 types of pex. A stands out from B n C. A will reform and retain its shape if it is crimped or bent such as happens to garden hose over time, where you want to chuck the hose because it's permanently bent. B is prolly what you find in the box store. C is a cheaper made version of B. B or C is better at dealing w dissolved oxygen, I forget. My municipality requires type A.
As for parts, people here mean push on fittings when they say sharkbite. Not an ideal long term product. Upanor and the mechanically fastened plastic rings are at the top of the list. In the box store you will find crimp rings (oteker) which I like and have used and wedding ring style press rings. Then you may come across plastic fittings and metal fittings. Plastic are fine and won't interact w water the way metal might. Also know that Upanor fittings are not interchangeable w the other type. --24.194.xxx.xxx

Done hundreds if not thousands of crimp styles connections on pex.... zero leaks. Ill never do copper, cpvc, etc --76.77.xxx.xxx

Great tips thanks everyone.
I will look into using the copper ring crimps. The areas I need to rework are all out in the open and easy to get to and see in case of a leak. --74.130.xxx.xxx

I used PEX for the first time about 20 years ago. I have several houses now with nothing but PEX and several more with PEX repairs.
I use the copper crimp rings. So far I had two joints leak, both leaked immediately and were because the crimp tool had failed. I bought a new crimp tool and kept going.
If you have municipal water, copper will likely last 60 years. If you have well water it may not. Our well water locally has a low pH, around 4.2. If the pH of the water is under 7, it is on the acetic side and will dissolve the copper little by little. Sooner or later the copper pipe will fail.
A stronger argument for inner city landlords: PEX has no value at the scrap yard. You will not have any junkies stealing your PEX pipes. --69.80.xx.xxx

Huge Pex fan!
Especially if you have had water supply lines freeze before --24.101.xxx.xxx
