Are Your Sharkbite Fittings Leaking? If So, Here’s How to Fix Them
August 25, 2022 - These remarkable devices join copper, CPVC, or PEX pipes together without the use of solder, glue, or even clamps. In fact, these fittings have little stainless-steel teeth that clamp down onto the inserted pipe. Once they clamp down, these fittings create a tight, waterproof seal. However, if your SharkBite fittings are leaking...

It looks like the paint on the pipe is causing your problems. I'd recommend shutting off the water, removing the shark bite connector, and stripping the paint for a couple inches on either side. The hardware store will have chemicals to help strip the paint so you don't have to do it all manually.

Here is a video of how to use emery cloth to clean a copper pipe. The video is a bit long for the topic but covers it well: https://www.youtube.com/watch?v=Q4LvzHt4m3M

When you reinsert it, SharkBite recommends 15/16" insertion depth for 1/2" pipe. Typically you should measure that distance from the end of the pipe and mark it with a permanent marker so you have a sight line for reference when pushing the fitting on.

You can also use any number of abrasive or sanding products but that paint has got to go. The wall of the pipe has to be absolutely free of debris.

Curious issue with sharkbite and cpvc | The Garage Journal
February 10, 2020 - What I found was the sharkbite separated from the inner and outer parts. The inner plug stayed in the cpvc and the outer brass came off. The inner plug was not fully seated but I was not able to push it any farther. Went to the store with a section of the pipe and the bite. The employee checked the bite plug on a new piece of cpvc and it fully seated with no friction.

r/Plumbing on Reddit: Experience with sharkbite connections to CPVC?
April 24, 2022 -

Does anyone have experience using SharkBites to connect to CPVC?

I had three faucets left in my house that still were using rigid plastic supply lines, I have had it on my to-do list to replace them with braided steel lines and finally got around to it today. After turning off the shut off valves at the faucets, I noticed several of them were leaking if it was in the fully-shut position. I went ahead and decided to replace the six shut-off valves as well (I've never done this before, but it looked easy enough). Was browsing through Lowe's and they had a ton of SharkBite products and a very quick look online seemed to be good reviews, the employee who was in the aisle seemed to really like them as well.

Got home, installed the 6 new shut off valves and the new water lines and did a little bit of research (after the fact, stupidly) and it seems like a lot of plumbers dislike them and say they're prone to failure? I hope I didn't just make a giant mistake trying to prevent a flood and instead ended up causing one in the future. They installed easy enough and I do not see any leaks right now. I only have a single story house so a slow leak wouldn't bother me (I'll just check them periodically especially this first week), I just want to make sure one of these things aren't going to blow off while I'm not home and flood my house...

Appreciate any help. Super worried that I made a mistake.

There are probably millions and millions of sharkbites working for years and years just fine as we speak. They are legal in a great many situations. That said, in my experience, they are most prone to fail of any legal method of pipe connection I can think of.

We use them regularly. They work great in your application. If it would start leaking later on, it's in a spot where you can see and replace it. The braided flexi lines you just put on should be replaced every 5-10 years if you're truly paranoid about flood damage.

When you cut your cpvc pipe make sure you do so where after cutting it the pipe is even or level from one side to the other, uneven or leaving one side of pipe cut higher or lower then other side will cause the sharkbite coupling not to slide in and snap in place and seal off, thus reason you are having water spray out or leak, remove the sharkbite coupling and re-cut your cpvc pipe evenly then slide it into sharkbite coupling until you feel it lock in or snap in or cannot push it in any further.
