About a week or so ago I did a PVC pipe project and I got all new materials. The pipe fit into the fittings easily, they bottomed out and didn't get stuck and were easy to remove. Likewise, while gluing, it was easy to insert the fittings.
Today I did another PVC project but this time it was different. The pipe didn't fit all the way to the bottom of the fittings, it got stuck like 2/3 in, and tended to stick together.. When gluing it was also rather hard to push the fittings in, I had to push hard to get them in. On the second to last connection, I looked in the piece of pipe to see the joint, and I saw this weird white thing; apparently the fitting scraped away some of the soft white PVC and made a shaving down there... I stuck my finger in and cleaned it out.
So first project, pipe and fittings fit easily and snugly without getting stuck, but a while later when I did this project, the fittings won't bottom out and they tend to get stuck and hard to remove. What could have happened? Does PVC absorb moisture and change properties or size or something?
