How Do You Glue PVC Irrigation Pipe?
With the right tools, putting together PVC irrigation piping is a straight-forward job. Lay new pipe in trenches or cut out a damaged part of existing piping with pipe cutters. Use purple primer on the outside of the clean pipe and the inside of the connector (elbow, tee, or whatever). Liberally cover the end of the pipe over the purple primer (that etches the pipe) with glue. Red hot glue is also a glue preferred by many folks — even though the color is bright blue. I like to add a light coating of glue inside the connecting piece as well — not too much. Glue should ooze out making a bead around the join. Slide the connector over pipe end with a bit of a twist so it goes on all the way. If connecting pipes, you will need to do this on both sides. The glue sets up very quickly and will probably hold under normal water pressure in less than an hour, but to do it ‘right’, you should wait 12 hours. If there will be a lot of water pressure, it’s best to wait until the glue dries thorough
