Pex: Crimp vs. Sharkbite?

I am interested in which connection provides a more secure connection. The other issues to me are secondary: Crimp is better for cost, Shark bite for convenience. If they both provide the same leakproofness, then I would probably choose sharkbite due to ease of install, reusability and no tool needed. I have heard some suppose that Sharkbite may rattle loose, but have not yet heard any actual anecdotes to support this.
Again, I will choose what has been proven through experience to be the best for providing a leakproof & secure (and lasting) water line.

I use pex and shark bites throughout when I make repairs. I haven't had one leak yet. You gotta love something that installs without glue or fire and can be removed and reused as necessary. It also allows you to interconnect with existing copper or cpvc that it in the camper. I personally can't see using anything else.

Shark Bite is something I don't consider permanant. Eventually, the O-rings will compress and leak. I have used similar connectors to Shark Bite and they work well but I am not sure I would want to see how they are doing in 20yrs. I am not sure for that matter how PEX would do in general over the long haul. Even copper has issues not associated with freezing. I would use crimp on copper rings with brass fittings not the plastic ones. Shark bite would be better than PEX with plastic crimp fittings.

Say what you want to, but the problem with the old PB tubing was not the tubing but the crappy plastic fittings.

20 yrs is considered permanant by manufactures these days maybe even 5 yrs is considered permanant. Expect problems on the hot water outlet to the water heater first. The higher the temperature the faster plastic and polymers age.

I crimp where I can, and sharkbite where there is no alternative.

I agree with Perry, O-rings take a set and loose their clamp with time and temp changes.

Can you say more about the issues related to the plastic fittings?

And what about the solid ring compression fitting vs. the ratcheting crimp fitting?

If you want the ultimate in PEX connection systems, look at Wirsbo AquePex and other expansion based systems. No crimp ring. Rather, they use an expandable collar placed over the end of the PEX, both are placed in a mandrel and expanded to accommodate a brass fitting, The PEX and collar then string to their original diameter………seamless, secure and easy to apply in tight spaces.

I still use SharkBites and Sea-Tec fittings as needed. Have been for 8 years and have not had one call back for leaking.

If the sharkbites and any other plumbing in my trailer needs no repair for 20 years, I'll be thrilled.

Despite needing a tool to crimp them (and therefore the space to use it), the crimp on connectors have to be destroyed to remove them and in a tight space, you may not even be able to get to them to destroy and remove them.

I agree with Perry that all plumbing systems have their issues (I trust I'm paraphrasing your statement correctly), and that copper rings with brass connectors should perform better over time than the compression style Sharkbite fittings. This is probably especially true in a trailer given the forces imposed on all systems by the trailers weight as it moves down the road. I replaced my previously frozen system with Pex and used the copper rings in all but 2 locations where I just couldn't get a good bite otherwise. After all I went through to get my trailer back to a useable condition, I'll be checking all my systems before I take it out for as long a I own it. I think it's the nature of the beast, and that commitment is probably part of ownership of a vintage AS.

I too crimped where I could and used a few shark bites where I could not crimp. The difference is cost is considerable, crimp rings are much cheaper.

I haven't started on my plumbing as of yet. But, I plan to crimp everywhere possible and use other fittings as necessary. Thankfully, a residential job I did a couple of years ago paid for the crimping tool.

The copper rings are better than the Stainless steel with the little ears you crimp. The ones with the ears may allow you to crimp in locations you can't get room for the big copper ring crimper tool. There is no reason with some planning that you can't assemble manifolds and other components and then install the assembly so you are not trying to crimp in impossible places. There are plastic PEX fittings and brass ones. You want the brass ones. The plastic ones can break and shrink over time.

There is a close quarters ratcheting tool for PEX crimp clamps. Of course it still requires some space but not nearly as much as the longer handled ones. You do need 2 hands to get it started though. That is unless you have Gorilla hands. They also make a tool for cutting the ratchet clamps off. Haven't seen this work yet. In the confined spaces of an AS I'm sure that even the close quarter tool just won't work sometimes but if you can get to it it will do as well as any of the tools.

pex connections

I have been using Watts fittings and crimp rings. The tool is relatively cheap and works in most tight spaces. Available at the big box stores all over the country.

Just curious, what makes the copper rings better?
