Is PVDC more like PVC or CPVC? I am remodeling a bath and the the water lines tubing is marked with PVDC? I need to cut and re-run some new connections and I am not sure what to use for the glue? should I use the PVC or CPVC glue? Or is there a universal glue for all?
Interesting case. PVC stands for polyvinyl chloride, whereas CPVC is chlorinated polyvinyl chloride. Both are manufactured from vinyl chloride. PVDC is polyvinylidene chloride, generally known as Saran (used in Saran wrap). I have never seen pipe made from this material. I am quite curious what type of glue to use, you probably should check with the manufacturer.
PDVC is normally a lining on pipe and tubing, not what the pipe/tubing is made of. It is used for corrosive material flow and is food grade. I have never seen or used this type of pipe, when using glue as an adhesive. Normally, coated piping is flared or threaded. Another thing is that some state codes have prohibited "all purpose" adhesives. Even though they can be found at Home Centers, they are not code.
If you have never made a mistake, you haven't done much.
