I just discovered that I mistakenly cut open a 5/8-inch copper supply pipe instead of the 1/2-inch one I've been working with in my bathroom. I need to cap this pipe so I can turn the water back on for my sink and shower until I can get the right parts sorted out tomorrow. Lowe's and Home Depot around me don't have anything for a 5/8-inch pipe, so what's the best way to handle this issue temporarily?

Honestly, I'd suggest picking up a SharkBite cap. Just push it on the end of the pipe. It’s pretty versatile, so grab one of each (1/2 and 3/4) if you're unsure and return the one that doesn't fit.
For a temporary fix, you might try using JB Weld if you're in a pinch. Just remember that this might not be a permanent solution, so plan to definitely be able to remove it later. Also, a cork could work for an even quicker cap as a last resort!
I seriously doubt that 5/8” is what you have; it’s typically just for gas lines. Most plumbing uses 1/2” or 3/4”, so you might be setting yourself up for trouble if you don’t double-check. That's why your valve doesn't fit!
If you really need to cap it, you can look for a 5/8-inch cap online. Amazon might have a compression cap coming, which could help you out. It's convenient, but just be aware it could take a bit to arrive. Have you thought about checking any local specialty plumbing stores or even Habitat for Humanity Restore? They often stock various supplies and could have your needed parts.
Good idea! I’ll check out the Restore and see what they have. Just want to get this water situation sorted out.
First off, are you absolutely sure the pipe is 5/8-inch? That size is pretty uncommon in plumbing. Just check if you can trace the line back to find a more standard size like 1/2 or 3/4 inches where you could install a shutoff instead. You might be looking at it wrong since the actual diameter differs from the nominal size. If you're confused about measuring, maybe just grab a caliper and double-check it!
Yeah, I know, the sizing can be a bit misleading! It's worth double-checking though since 5/8-inch is often just HVAC stuff, not typical for water lines in homes. Also, your current fittings may not fit simply because they are meant for different pipe dimensions.
I totally get it. It's frustrating! My 1/2-inch fittings never fit when I cut into the wrong size. It might just be that the copper pipe's wall is thicker than expected. If that's the case, maybe see if you can sand it down just a tiny bit to fit the other fittings.
Yeah, I’ve checked a few local stores, but they seemed to be out. I just ordered a compression valve from Amazon too, which should arrive tomorrow. Fingers crossed it fits!
