My first actual plumbing project done entirely on my own, replaced leaking black 3" flex piping w pvc, about 6 feet. In the end the cement I had was old and consistency of jelly. Instead of going out and buying new I went ahead used it and now I'm haunted/scared. It came out really clean and I now have much regret for not taking the final step correctly.

The place I repaired is intake from gravity fed 3" piping direct from irrigation ditch to my yard (3" intake reduced to 1.5", 90° up, 90° over), where it comes in to my pump, so the parts I replaced aren't under direct pressure. What scares me most is once the ditch opens up, whatever the results of my work I may be stuck until the end of the season to replace/repair.

Ditch opens up in April. How fucked am I?
