PVC Safety


In response to a comment from a local plumber I am now concerned that my drinking water may not be safe for my family. I recently bought a new house (it was built in 1989) and noticed that the supply side of the plumbing system uses ¾” schedule 40 PVC. This plumber told me that PVC can not be used for potable water. He recommended removing it all and replacing it with copper. Let me detail the system; ¾” copper from the street, through the foundation and to the meter. After the meter, ¾” schedule 40 PVC that has a stamp right on the pipe that says “DRINKING WATER” this PVC leads to a distribution manifold and to the water heater. ½” pex carries the rest of the cold water from the manifold. On the hot side of the water heater ¾” CPVC caries the hot water to another manifold and then again ½” pex carries the hot water from there. Is the safety of my family at risk? Should I consider replacing the PVC? Any info would be appreciated.

This is allowed and safe. PVC is okay for cold water only no hot water. The CPVC is okay for both. The pex is the way to go and should be used if you decide to change anything or add to your system.

plumbers like copper it takes much longer and they are used to it. Takes forever for them to understand PEX is great. And it has been around since 1983...

Bob's right. Nothing wrong with any of the listed products. As far as I'm concerned, PVC, CPVC and PEX are completely safe unless you eat or smoke them.

Plumber's LOVE copper, Simply LOVE copper.

When I plumb I use copper as much as I can but, in today's times I use other piping

For example..Today I went to a service call where when the bath tub faucet and Lavatory are on at the same time there is no water pressuer.

Service line from meter to house is 75 ft long

75 ft "L" copper $4.00 p/f Total $300
75 ft Pro core Total $30

Copper is just so shinney and pretty it is simply old school plumbing.

This guy was trying to make a buck. Have him pull out the code book for approved water "potable" line

ME TOOOOOOOOOOO

But some of my customers don't like the price. I know that my competition is bidding pex, pvc and others so to get the job I have to be in that ball park.
