Purple PVC primer turned pink

[maradcliff]

This is the first time I have ever seen this happen. That purple primer for PVC pipe cement was in my garage for better than a year. I went to use it last week, and it turned pink in color. I still used it, the joint held together, but they usually stick together with just the cement too. However, I have always used all three, the cleaner, primer, and cement. That way I know I have a good joint. I dont understand the color change. I didn't get anything mixed into it. Has anyone else seen this happen? Any idea why?

purple primer and clear cleaner, are`nt they the same thing ?

never had pink ;)

Settling? Give it a good shake.. Possibly part of the mix settled in the bottom and thickened up?

Never used it myself so these are just guesses.

Never saw it happen, because I never use the primer. It isn't necessary. For that matter, I never use the "PVC cleaner" either. Acetone does just as good a job, and costs about one-tenth as much. All you need to make a good joint is acetone, and PVC cement. Don't worry about the primer. You don't need it.

Advice like this can be counterproductive. I have never seen primer lose its purple.

Many inspectors consider primer as a bare minimum as do glue manufacturers and pvc manufacturers. The whole reason for the gawd awful purple color is for easy identification by inspectors, required in some codes.

Here: No Purple, no pass.
