The other side of the coin is this:

Look how long they used asbestos in building insulations and other products before they found out that asbestos dust could be dangerous.

They used lead carbonate in paints forever until they found out that lead gets absorbed into growing tissues, like babies and other growing stuff.

At least with copper, there's been 50 years of "so far so good" and no problems other than lead soldering in joints, and even that remains questionable.

When plastic piping has been around for 50 years, then we can call it safe. Until then there's always the possibility of turning on the TV and hearing that some scientist somewhere has noticed a truly excellent correlation between PVC water supply piping (in it's various forms) and the incidence of brain cancer (or leukemia or being born left handed or God knows what else).

The one small point to be made for copper, is that it's got a long track record.

PE pipe has been around since the early 1960s. Millions of people use it in their wells to 500' and underground to the building. Water companies have used it for service lines from the street. I've used it for 20 years.

It is inert meaning it adds nothing to the water, unlike copper which is dangerous to humans, nothing in water can harm it like copper can be like acidic water and bacteria and high DO, TDS and CO or electrical grounds or stray electrical currents caused pinhole leaks.

One person can handle a 500' roll easily and you simply unroll it into the trench as you walk along behind it along side the trench. It will roam from one side of the trench to the other and you do not need to worry about contraction/expansion problems as you do with PVC or copper. It has the least friction pressure loss and you only need a fitting on each end. If frozen it is the most forgiving of all materials.

It is common in rolls from 100, 200, 300, 500 and 1000' rolls. And is commonly found with ratings of 75, 125, 160 and 200 psi. For pressure lines I suggest 160 or 200 psi.

To use insert/barbed fittings, you warm teh end of the tubnig evenly and wait to tighten clamps until it cools and duble oppse clamp it with SS clamps if the fitting is underground, above ground one clamp is sufficient. All clamps should be tightened properly with a small T handle ratchet type hose clamp torque wrench sold where you buy the clamps or at an auto parts store.

So what's not to love?
