 FAILED WELD huge leak, did emergency repair
Author: airbornebaby (WA)

So my question is can our emergency repair be used permanently, or how long would it last?

The plumbing to master shower had a weld fail and leaked. In order to quick repair to get the water back on, we used a "repair hose connector" and cut out the section of the leak.
Can this hose last? A handyman friend told us to use it, it's working great for now. He suggested it could last 30 years. But the tag says only use on exposed plumbing. Do we need to have a new copper section welded into place?

To answer your question, Yes. In an attempt to clarify the question, welding is when you attach two or more pieces of metal i.e. iron or stainless steel by near melting of the base metal.

Soldering is defined as a group of joining processes that produce coalescence of materials by heating them to the soldering temperature and by using a filler metal (solder) having a liquidus not exceeding 840F (450C) and below the solidus of the base metals. The solder is distributed between closely fitted faying surfaces of the joint by capillary action.

Brazing joins materials by heating them in the presence of a filler metal having a liquidus above 840F (450C) but below the solidus of the base metals. Heating may be provided by a variety of processes. The filler metal distributes itself between the closely fitted surfaces of the joint by capillary action. Brazing differs from soldering, in that soldering filler metals have a liquidus below 840F (450C).

To simplify the above paragraphs. Use Oxygen and acetylene for welding ferrous metals and Map gas or butane for soldering copper tubing (non-ferrous) together.

I guess a piece of garden hose would work too, but you need to consider the long-term reliability of the repair. And if it is hidden you won't know if it leaks, nor will the next person living there.

Walking through a lake inside your residence might be the first clue that it has failed.

Thanks for the quick responses.

I'm pretty sure though, that most of the members of this forum would prefer to go without the acrid, offensive tone SOME of you write with.
Yes, I read the tag, duh, I received advice contrary to my assumptions from someone with more experience than I. That's why I asked the question. The rudeness was completely uncalled for.

It was an impression of Homer Simpson. Not a 'duh' but a D'oh. It's one of the hazards of the written word, as opposed to a face to face conversation. If I was a friend standing next to you, and you asked me the question, I'd smile at you, read the tag aloud, then pretend to knock on your head, and ask if anyone was home. People tend to take offense at the way I write too. It is straight forward, the way I would speak to a friend at the kitchen table.In the case of this forum.....what would you say is the most important....politically correct, or correct?

sorry, meant no offense

You DID read the tag, yet you STILL asked.

To answer: It is not advisable to conceal a temporary emergency 'repair coupling'.

Even if your 'maintenance man' says it may hold for 30 years, it 'probably' will NOT.

Terminology is everything in the piping trades.

If you hire a 'pro' and request that copper tubing be 'welded' they may break out the brazing gear at GREAT expense to yourself.

welding - brazing - soldering are DIFFERENT forms of joining pipe / tubing

D'OH

wait for it
