Melsandman,
Hehehehe!!! That was cool, the seventy. I remember that time, drinking left over beer and smoking ######. But anyway, Yep, that is what I meant. Depends on which glue you are using. You are talking about the pvc glue that has kind of like purple color right ? The glue should be harden quickly, but since we are using it for salt water. We should let it sit for a while. Remember not to put a big amount on the pipe that it would drip all over the place. Make sure that it should be no glue inside the pipe where the salt water would flow through.
Later,
Mattt.
