Go to the hardware store and buy a "sprinkler riser removal tool." I have removed several with one of these, works perfect.

Well, that didn't work. It sure gripped but I couldn't turn it. I'm going to get my stronger neighbor to give it a go and then try something else. I wonder if it's because it's nylon and the sprinkler heads are maybe pvc?


With a tool like that you are expanding the plug making it even tighter.
Heat up a screwdriver and melt a couple groves (top and bottom) in the plug right down to the metal water heater threads.
Then take the screwdriver (once cooled), place it between the plug and the water heater thread and pry the plug out.

Sorry I didn't post a conclusion to this. By now, I have forgotten exactly how I removed it but it seems like I grabbed what I could with pliers or vice grips and plied, pull, tore it out I think. Unfortunately, threads were boogered just enough that I couldn't get even a metal plug to run in and clean the threads, primarily because the very edge got boogered as well, thus preventing anything from starting. I believe I then minimally got a tap started, ran it in slightly, then replaced it with the metal plug, which I kept advancing as far as I could comfortably and following it again over and over with the metal plug, then finally inserting the plastic plug. Either the threads are longer on the new plugs or I don't have it fully inserted, but it feels as tight as I want to chance. I will know once I hook up next spring, at which time I believe some teflon tape will finish the job if it is leaking. I certainly hope so lol. Thanks everyone.
