White (water) PVC is pressure rated and gray (Electrical) PVC is not. White PVC is softer than Gray so it bends easier. Gray uses the single step clear PVC cement won’t leave blue or read stains as many times it’s in the open and can be seen. (Note you can use the clear cement on white for non pressure uses.)Click to see full answer. Likewise, can you use gray PVC for water?There are two common types of PVC pipe – schedule 40 PVC and schedule 80 PVC. Schedule 40 PVC is usually white in color and schedule 80 is usually a dark gray (they can also be found in other colors). This pipe is best suited for drainage, irrigation, and other cold water systems.Also Know, what is the difference between white PVC and GREY PVC? However, the kinds of fittings sold for each differs. White PVC pipe fittings tend to be small with tight curves, good for flowing water. Grey PVC pipe fittings tend to be large with broad curves several centimeters in length, good for pushing wire through. Grey PVC fittings often can’t hold pressure. Additionally, can you use PVC glue on conduit? PVC Cement The “glue” used to join rigid PVC conduit and fittings is officially called PVC solvent cement. It comes in a small metal can with a twist-off cap, and is the same material used to join PVC plastic plumbing pipes and fittings. Avoid these, and buy one that is intended for use with PVC pipe only.Is PVC glue the same as PVC cement?A: Solvent welding is a chemical process that uses a primer, or the cement itself, to soften the surface of plastic pipe and fittings in order to weld, or fuse them together. Glue such as PVC glue, on the other hand, is only a bonding cement and will not work with an interference fit.
