PVC pipe Polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (CPVC) pipes both are resistant to damage from hypochlorite. CPVC has a higher temperature rating. PVC is the cheaper alternative and is readily available. PVC glue Normal glue uses fumed silica (finely ground glass) for thickening. The high pH of the
