Rommel:

You indicate that the PVC is being used for DI. I assume that is deionized water. Don't assume that DI water is an easy, straightforward use for PVC. DI water is quite corrosive and PVC (and typical PVC pipe cements) is not always a good choice for DI, depending on the conductivity of the water. CPVC and CPVC joint cement are better, but still often not the best solution. Your problem might not be the quality of the installation but the materials selection.

Dear All,

We are having a problem with our plant regarding the newly installed PVC pipes, we have encountered a lot of leaks from the joints, our current DI pressure is 80 psi.Can any one send me the procedure of PVC pipe installation, i know this problem is workmanship, they are using Weld-on as pipe cement for PVC joints.

Thanks,

Rommel
