Pex Fail


I ran a 3/4" pex line to my shop from the house. All copper in house. I used a Sharkbit ell to join pex/copper. It leaks around the Pex. There is a slight score line the entire length of pex. Any ideas?

Re: Pex Fail


Get rid of the Sharkbit , Crimp a fitting on the pex to connect to the copper.

Yeah that's what I figured Randy. Was just hoping there was a trick I was unaware of. Thanks.

Re: Pex Fail


Try to reset it, or replace the fitting. And check that it was fully pushed in.

My buddy re-plumbed his house on them a few years back. He's on well water. The sharkbites failed miserably with corrosion.

Re: Pex Fail


Shark bite fittings are for temporary repairs, in my opinion, I would never leave one inside of a wall, or someplace inaccessible.

Re: Pex Fail


Replace the shark bite with a crimp or expander pex fitting. Shark bites are a temporary fitting.

Re: Pex Fail


You say there is a score mark the length of the pex. Are we talking from the house connection to the shop?

I don't use sharkbites that often, but they are approved, and function fine, in both exposed and concealed work.

But, if it would make you feel better, there are compression fittings for attaching copper to pex. You MUST be sure to use the little brass or stainless insert that comes with it, or it WILL leak.

Re: Pex Fail


Yes the score is the full length of the pipe. I think that's causing the o-ring to not seal.

Is the pex exposed to sunlight?

Why do I get a feeling that we'll be reading about massive water damage lawsuits over Sharkbite in the future?
I'll admit I don't have too much experience with them. In fact I've only come across two in the wild and both were leaking and the reason I was there. I sure hope I'm wrong and that I've unknowingly been around thousands of working good ones, but I'm very hesitant to use them on my own house and I haven't seen any plumbers around here using them.

Re: Pex Fail


I remember using some back when they were just getting popular. The company I was working for had us keep some on us for capping water lines when vanities with no shut offs came out etc. But we also fixed the odd pipe that got knocked during tear out and I recall using one of their shut offs on a job once to replace a leaking shut off. I dont think many got buried in walls but I hadnt thought about it much until this thread.... I never did trust them honestly.

Re: Pex Fail


I remember the PB revolution of the early 80's when it was the wave of the future, and the lawsuits it faced upon it's total failure. I also remember the new and improved all problems fixed PB wave of the late 80's, and the lawsuits it faced from it's failures.

PEX failures have been noted throughout Europe for years, but are not well known because of their lack of a full blown tort law freedom, and they will continue to grow in this country as problems get attention of lawyers, it's the nature of the game...

Sharkbites are based on the same technology, and will suffer the same fate over time.

Eric: No my PEX is not exposed to sunlight. Will toss out the Sharkbite and replace with a PEX fitting.

Re: Pex Fail


I'd be more concerned about that score mark the length of the pex first.



For the record, I use soldered copper on all my plumbing installs. I've used sharkbites a couple times when the old copper was so thin it couldn't be soldered, and it was a repair, not a re-pipe.

I've never done a full install with pex, either.

I'm quite familiar with the PB debacle. I've always said that that was where pex was heading. But I haven't heard of any actual pex failures.

I'd be interested in reading about these failures in Europe. I know it's been in service over there a lot longer than here.

Re: Pex Fail


Mildly amusing anecdote:

I was in the plumbing wholesaler the other day, buying a bunch of copper fittings, and the kid says to me, "Hey, you ever seen our Pro-Press stuff?"

Uh..Yea. I've seen Pro-Press for decades. I just don't have a Pro-Press tool. My torch and roll of solder works fine.

I told him, "I have a flip phone and a CB radio in my truck. Soldering works fine."

Re: Pex Fail


Crimps are used if the water is corrosive to the sharkbite fittings. Other than that, they are pass to leave in walls. Most guys I've known will only use them for temp fittings. The Pex has to be score free and the cut has to be even with the fitting pushed all the way in. I've never had a problem with them leaking if installed properly.
