What is the difference between purple and clear PVC primer?
The purple is so that the building inspector can tell that the plumber used primer by visual inspection. Clear is fine to use.
Why is PVC primer dyed purple?
The purpose of the primer is to clean and soften the outer coating of the pipe so that the actual cement will bond more effectively. The purple color is just a dye so that it’s easier to identify whether or not primer has been used on a particular joint.
Is PVC cleaner and primer the same?
The cleaner is formulated to remove surface dirt and any oil or grease that exists on the pipe from the manufacturing process. Primer/cleaner and primer contain more aggressive solvents and will soften the pipe surface to allow the solvent cement to penetrate more effectively.
