Default Pex experts....question

I’m not an expert in the world of pex. I have always been of the opinion that I shouldn’t mix different manufacturers fittings/joining methods with different manufacturers tubing. My worry is if something would go wrong I would have two manufacturers pointing the finger at each other with me stuck in the middle.

Which brings me today- I looked at a 3/4 compression fitting that some dipshiit put on 3/4” pex. It blew off over the weekend when no one was home and flooded the place.

The pex is shark bite brand. I don’t have any shark bite branded pex fittings for r their crimp tool. I’m not apposed to buying it but it’s made me wonder if mixing manufacturers tubing and fitting is really that big of a deal.

So tell me your thoughts. Am I worried about nothing? What do you all do?

I mix pex brands fitting and pipe every day without noticing. I buy stuff at regular price and some on sale in other stores. I do stay with the popular brands though. Ipex, Bow and some other.



As for SB brand pex I wouldn't worry about it. Imagine all the DIY buying different brands and they all leaked or popped, we'd of known by now not to mix brands.


On a side note :
I stay away from aqua dynamic balls valves. I've got 3-4 that leaked. One of them I used for a house main and I had to call the city back to be able to change it out in a difficult spot.

Well myself that’s the one place I will use a sharky b. I’m no pex expert either but I just recently learned there’s 3 different formulations of pex which all have their own properties regarding flexibility and stretchieness and memory - I’m paranoid to stretch pipe that wasn’t designed for it - obviously the expander tool is the one I use. It’s too rare that I run across pex needing repair for me to justify buying a crimp tool so push fitting is my answer - even though it wouldn’t be my first choice, I think it’s fine to use on those rare occasions.

To those of you who do mix fittings/pipe - which connection type are you using? All crimp or all expanded?

Something that's probably not really apparent to the DIY community or any of the box stores.

As far as I know, you can crimp any brand, Wirsbo included. You can only expand Wirsbo/Uponor though
sparky, skoronesa and Spacepirate like this.

LISTEN....
you are better off to just save yourself a lot of time and misery and just admit that a sharkbite fitting is a universal repair fitting for ALL pexes except for KI-Tech pipe... Duhhhh That is what a sharkbite is best used for.... There I have said it.......

We have repaired old style grey poly with sharkbites and gotten ourselves out of terrible jams and messes that could have literally ruined a whole day attempting to find suitable fittings for..... and of course its always in a mobile home or old house where the customer does not have a pot to piss in and cant afford a re-pipe

I would never re-pipe a house in sharkbite fittings but I have seen it done before.....

Sharkbites are best for adapting different brands of pexes togethor
...there I have said it again.... and I am no less a man for admitting it....


just say this mantra over a few times like a meditation..

their is no shame in using sharkbites,
there is no shame in using sharkbites
their is no shame in using sharkbites,
there is no shame in using sharkbites
their is no shame in using sharkbites,
there is no shame in using sharkbites

You are not supposed to crimp wirsbo... They even had a re-call on some clamp type system they tried back in about 2005...

. maybe it will last a while but I would not want the troubles that could happen when that hot line decides to pull apart in a ceiling.... WIRSBO is the best system out there ....It wont freeze and break and the compression tool made by milwaukee is the best on the market...

Does anyone know when the patent expires, so that less expensive alternatives will be available?
