Best way to fix a leaking pipe joint?

[Annahmed]

Hello everyone!

What’s the best way to repair or replace a leaking pipe joint? Is it better to use a repair clamp, epoxy, or replace the entire section? Any tips for those new to plumbing repairs?

Thank you in advance.

Hi there!
If the leak is small and you need a quick fix, a repair clamp or epoxy can definitely buy you some time. Epoxy works best if the pipe is dry when you apply it, and clamps are great for slowing or stopping leaks without much prep.

But if you want a long-term fix, replacing the leaking section is usually the best way to go. That way you’re not just patching over a problem that might get worse later. It can seem a little intimidating if you’re new to plumbing, but with the right fittings and a bit of patience, it’s totally doable. Just make sure to shut off the water and dry everything well before starting.

Appreciate the advice! Any specific brands or types of repair clamps or epoxy you’d recommend for a copper pipe?

[TinyTool]

For copper pipes, a high-quality repair clamp made specifically for metal pipes is a solid option. Look for stainless steel clamps with a rubber gasket inside, they’re usually labeled for copper or metal use and tend to hold up well under pressure. As for epoxy, epoxy putty sticks work well because you can mold them around the joint, and they harden quickly. Just make sure the pipe is clean and completely dry before applying it, or it won’t bond properly. Both options can work well for a temporary fix, but if the leak is serious or near a soldered joint, it’s a good idea to plan for a full replacement when you can.

Thanks for the info! I was also wondering, are push-fit fittings considered reliable for long-term use, or are they more of a temporary solution?

[TinyTool]

Glad I could help! As for push-fit fittings, they can definitely work long-term, but it really depends on where and how they’re used. They’re super convenient for quick fixes, and work well in places like under sinks or in tight spaces. That said, if you’re dealing with high-pressure spots or areas that might move around a lot, a traditional soldered or threaded connection might be a safer option. The good thing is, a lot of modern push-fit fittings are designed to be pretty durable. Just make sure to follow the installation instructions, and you should be good to go.

One thing I’ve been wondering, if a push-fit fitting fails, does it usually give any warning signs like a slow drip, or can it just pop off suddenly and cause major flooding? I imagine that would make a big difference when deciding whether to use them behind walls or in visible areas.

[TinyTool]

Most of the time, if a push-fit fitting is going to fail, it will start with a slow drip or small leak. This usually happens if it wasn’t installed properly or if the pipe wasn’t cut clean and square. Sudden pop-offs are rare, but they can happen if the pipe wasn’t pushed in all the way or if it’s under constant movement or high pressure.

That’s why many people recommend using push-fits only in places where you can access them easily. For anything behind walls or ceilings, it’s usually safer to go with soldered or compression fittings for peace of mind.

Thanks for all the help, TinyTool. One last thing, if you ever need to remove a push-fit fitting, is it reusable, or should it always be replaced with a new one?

[TinyTool]

In most cases, push-fit fittings can be reused as long as they’re in good condition and weren’t damaged during removal. You’ll need the right removal tool to disconnect them cleanly. Some people still prefer to replace them just to be on the safe side, especially if it's a key connection or if the fitting looks worn.

Sounds like reusing them can work as long as they’re in good condition. Appreciate the help!
