I am replacing 4"PVC sewer pipe with the bell and spigot ends with the gasket in the bell. How do you get the two ends to go together? I've tried dish soap and vaseline as lubricants but cannot get the two ends to connect... any ideas?

Insert the neoprene gasket,(see image) into the hub. Do not grease the outside of the gasket before inserting. Now take a hammer and bevel the sharp edges of the cast iron , or a file and bevel the edges of PVC, so the pipe won't hang up on the ridges in the gasket. Next lube the pipe and the inside of the gasket with Dual-Tite Lubricant or a heavy grease. Push the pipe in, making sure that it's lined up until it seats on the bottom of the hub. We use a Johnson Bar for leverage but you can use a 2X4. If the pipe's difficult to start it's OK to trim back the first few ridges of the gasket with a sharp knife. Good luck, Tom
