The people who make copper pipes, thats WHO.

I would like you to document that claim. I have talked to repres of copper pipe companies and they typical guarantee for 15 years, But if you have another source i woulds like to see it.

Always the troublemaker, eh Bill? :p:cool:

IMHO, copper pipe longevity TOTALLY depends upon the pH of your water source. I've seen well systems that required brass fittings because copper disintegrated within a few years. The brass didn't fair much better, but it did last a few years longer. I've also seen 30 year old copper in excellent condition, so what's the lifespan of copper, it's totally dependent upon your water pH.

A slight caveat is that copper that didn't have the flux wiped off of it when it was soldered will develop pin holes due to the acidity of the flux. Another issue is when copper was run in concrete slabs, the expansion and contraction of the pipe against the concrete would wear holes into the pipe.

When copper is run in a concrete slap it shouldn't come in contact with the concrete. It's run below the slap with earth between the concrete and the slap and sleeved where it penetrates the slab.

True, but this doesn't stop people from doing it improperly. To this day I still find copper in contact with concrete. In fact, I toured a new development a few years ago where this was being done.

I've seen this too...copper pipes without sleeves, with torn sleeves...in dirt and in concrete. Shoddy workmanship that will be caught, if at all, long after any warranty expires.

Not all plumbers follow what has to be done, if not being watched like a hawk. On the other hand, there are plumbers who can be fully trusted to do their job correctly.

Thanks very much for this web page it said

Copper tube is the only material approved for water-supply piping that carries a 50-year warranty backed by the manufacturer. The manufacturer warrants that, when properly installed, its product will be free of failure as a result of defects in material or workmanship in manufacturing the product.

This i can agree with but not the 75 years originally claimed, I like the way the guarantee states that it must be install, correctly sized, protected from corrosion ect ect. thanks keith i can now call this race finished
