We're getting a water filter system put in and the plumber is recommending we get rid of the copper supply line and go with PVC. I'm concerned about phthalates in the PVC especially since the water is acidic. (ph of about 6.7) I'd rather not be drinking plastic, so I was wondering should I stay with the copper pipe, go with the PVC, or go with polypropylene pipe such as Aquatherm pipe (aquathermpipe )
get rid of copper? i think he is just trying to make the job easier for himself....its a no brainer......keep the copper
I believe the copper will breakdown quicker with the acidic water and old copper may have lead solder. I would say the aquathermpipe is best but PVC would be my choice do to cost and break down composition. your water is acidic but not so that it will do what your brain is telling you acidic means. If this makes sense.
I have never heard of a plumber recommending plastic over copper. Especially not replacing copper with plastic. It's commoon for new construction to use PEX tubing. It saves time, but it's not better or more reliable in the long run than copper. For all practical purposes copper will not deteriorate in your lifetime. It will not just spring a leak or crack. I cannot imagine what the advantage would be to using PVC except maybe an easier intallation and less labor hours. PVC is not really rated for supply. CPVC is rated for hot and cold water supply. It's not really much cheaper than copper. It is subject to cracking, vibration, and accidental damage. It can also freeze and break easier if you were to lose power for several days in very cold weather. People can easily break or rupture CPVC tubing with nails and screws. I don't trust it. The damage that can be cause by a large water leak is huge.
If your copper is old it's likely soldered with lead solder, which is much more poisonous than any of the PVC's or plastics. Also, the EPA is learning that copper pipe it's self can emit poisonous levels of copper into the water. While they haven't outlawed copper yet some experts are recommending that if the water sits in copper pipes for over six hours the pipe be flushed before using the water for cooking or drinking because the acids in water can cause corrosion and the corrosion then finds it's way into the water. And some even say don't use hot water from copper pipe at all since hot water accelerates the corrosion and leaching of copper poison. Your choice, lead/copper or plastic poisoning.
copper is always best,but it cost more,copper also helps kills bacteria in the water,but new homes use mostly PVC today,hope this helps.
