I think we all find these few stories alarming . There are many thousands of copper leaks each year And Mark feels pretty good about the track record on his home and I see very good service from copper, I've also repiped houses as new as 17 years that had copper. And heard of repiping entire tracts of homes paid by lawsuits that had copper less than 10 years old.
Does 1 house in a thousand get a PEX leak ? or 1 in 10,000? no one likes leaks except the repiper or drywall patcher but lets not get too worried
My house needed repiping because of low .pH well water. Swiss cheese copper... I installed an acid mitigation system but of course it was too late. If I repiped in copper with the acid tank, there would not be any further issue.
I wonder if the Uponor leaks are in systems with an abnormally high level of chlorine. If so, I wonder if Uponor is paying for a repipe with more Uponor product, and will they guarantee it again if it starts leaking in 10 years? Can chlorine be easily filtered out I wonder?
If it's a chlorine issue on some water systems, then other Uponor installations may last 100 years.
