3 foot section of copper pipe that had developed a pinhole leak. ... Our water here (Vancouver BC) is really soft.

While it could be the fitting, my initial reaction to this confluence of factors is "Well, then copper pipe is a terrible idea, and replacing a single section of copper pipe due to a pinhole is doing nothing about all the other sections of coper pipe being eaten by the water."

Where copper pipe is eaten by the water chemistry, you either need to alter the water chemistry or use pipe that does not corrode. And if you are replacing copper pipe that has been eaten, you need to look large-scale, because every bit of copper pipe in your house has been exposed to the same water for roughly the same amount of time.

So my first guess would be that the leak is most likely coming from the pipe beyond the replaced section.

r/Plumbing on Reddit: SharkBite lifespan first hand experiences
January 10, 2019 -

A lot of the posts about SharkBite fittings are doom and gloom stories about how they failed and leaked after a few years. Of course there are a few success stories with people saying they have been stable for a few years as well. However; unlike the old technologies of compression, PVC, copper, etc; a few years is not really that great. Copper and PVC fittings can last 50 or more years. Even ProPress fittings have a warranty of 50 years (but who knows since they are so new).

Does anyone have long term SharkBite experiences? I'm talking like 15+ years?

August 14, 2025 - SharkBite fittings are specifically designed for permanent connection and aren’t intended to be disconnected and reconnected repeatedly. In fact, the only way to remove them properly is to use the SharkBite PRO disconnect tool, tongs or clips. We’ve also designed our fittings with long-term use in mind.

My view on Sharkbite Fittings:

They are great for exposed plumbing. Especially for water heaters. They make a great quick disconnect system for appliances. I also am a big fan of their shutoff valves.

What I would not use them for us concealed work behind walls and ceilings. They are rated for it it they claim the rubber seal will last more than 20 years and are resistant to deterioration from corrosive water. But I simply don't trust them. I want my pipes to last 50 years.

The key to a good sharkbite connection is proper preparation of the pipe. Of you're using PEX, it's a no brainer. If you're using copper, you need to properly debur the fitting. Inserting a jagged sharp edge of copper into the fitting can tear the rubber o ring inside the sharkbite fitting. Also, don't use Emery cloth the clean the end of the pipe like you do when soldering. This can also cause a leak.

r/DIY on Reddit: How reliable are SharkBite fittings?
November 8, 2013 -

Hi all,

So the pipe going outside to my faucet froze over the winter and it burst. I was going to call a plumber, because soldering new pipes is above my DIY level, but I've been reading about these SharkBite push on fittings. They seem to be good, but I was wondering if any redditors here have had experiences, good or bad, with them.

Thanks!

Answer (1 of 7): They are considered permanent and should last a long time. However, the water tight seal is achieved by an o-ring inside and I think whatever material it is made of will disintegrate and fail before most other piping components.
