PVC Elbows

Connecting a PVC elbow depends on whether the elbow is a slip type or threaded. To connect slip elbows, apply PVC cement to both the outside of the pipe and the inside of the elbow socket, then join the pieces. To connect threaded elbows, wrap the male threads with Teflon tape then screw the elbow onto the pipe by hand.

PVC elbows typically do require both primer and PVC cement to create a proper solvent-welded connection. The primer cleans and softens the PVC surface, while the cement chemically fuses the pipe and fitting together, forming a strong, leak-resistant joint. This process is especially important for high-pressure irrigation lines.

Angles aside, standard PVC elbow sizes typically range from ½ inch to 4 inches for most residential irrigation applications. Larger elbows, such as 3" or 4", are often used in commercial irrigation or drainage systems. Always choose an elbow that matches the same nominal pipe size as your PVC pipe to ensure a proper solvent-weld connection with primer and PVC cement.

In most cases, leaks mean the joint wasn’t glued properly or the threads weren’t sealed well. If it’s a slip connection, you’ll likely need to cut out and replace the elbow if it’s leaking at the glued joint. If it’s a threaded elbow, you may be able to unscrew and reseal it without cutting the pipe.
