Pvc

[Al D. Bolt]

Can anyone tell me why PVC should not be used as hot & cold water distribution piping?

Thanks.

It does not hold up to the constant pressure and heat of a distribution system. If you want to use a similar product, use CPVC that is approved for this application.

Cuz the codes say so. . .

Corrosion resistant pressure pipe, IPS sizes 1/8” through 24”, for use at temperatures up to and including 140 °F.

Also refer to IRC:

Hope this helps.
