I am working with PVC welding for the first time. I am raising the height of a toilet flange using a coupler and a new section of 3" PVC. The coupler does not slide "easily" onto the PVC pipe. It goes on to the shoulder all the way, but with considerable effort. I've never used PVC glue before. Will it lubricate the coupler and allow it to slide on more easily? Or do I need to sand down the surfaces so they slide together more easily?
Thanks.
Thanks.
