rugged, you say "PB, BLUE MAX, PEX < All plastic piping systems...now they are all combined with legal issues stemming from its use.".
I agree, you're right. And I agree that many people are suffering huge financial and emotional losses due to leaking water lines.
What I disagree with and IMO you are wrong in, is your implying/inferring that all plastic everywhere is bad and shouldn't be used by anyone at anytime.
Doing that is like saying vehicles should be banned because of the litterally million plus people per year, year after year for the last 50 plus years, that suffer life changing serious injuries and their expense.
You will not admit to any problems with copper that is causing large numbers of people the same expensive damages and emotional time bomb life changing distress as those with plastic water lines.
They have the same holes in the wall and until the copper is torn out and replaced, more leaks to look forward to, no matter if it's a retired couple on $400/month SS in an apartment or a single mother with four kids in her divorce settlement 4 bedroom slum or $500K house/condo she worked 24 hrs. a day over the last 20 years for.
It's all terrible, period. Yet we all need affordable water lines in our houses. There is no even close to perfect defect free water line material; or accident free vehicle. So all that proves is that life is a risk and living is risky, but it still beats the only alternative.
The truth is that the vast majority of residential water lines never leak before they are torn out of the building because of low flow or during a remodel etc. and most of us never have a vehicular accident with any more than minor injuries.
I suggest we all admit it, evaluate the causes of both leaking water lines in houses/buildings and of vehicular accidents and prevent as many as possible and move on making everyone's lives better. All that depends on accurate information and gossip prevents accuracy and gets many going in the wrong direction which simply adds to the problems they are trying to solve.
