A friend of mine Scott showed me the trick that worked on a cap that had not been removed in 50 + years. After trying to loosen the cap he then tried tightening the cap an it moved in the tightening direction about an inch after which he turned it in the loosening direction. Thanks Scott

@ BV001154 thanks!
from a woman: this plug/cleanout/cap in my house probably has not been removed since the house was built in 1938. i couldn't get it unscrewed. it had been painted over and blah, blah, blah . . .
because of your post i got a heavy duty short sledge type hammer. i gave it some hard bangs. not only on the side of the pipe on the end where the cap is but also on the head of the cap. i then tried to unscrew. still too hard. i could not. so i got my feet centered firmly on the ladder and had the pipe wrench vertical like a gym bar with both hands firmly gripping. i slightly bent my knees and lost contact with my feet and the ladder. all my 130 lbs. was hanging from the pipe wrench. the cap unscrewed!

Hammer the top until it begins to collapses while leaving a hole in the center. If you are careful after collapsing it, the center will not fall into the drain line. If it does, make sure you reach in and grab it.
OK, now you have a hole. Take a sawzaw and cut a 1/4 of the pie out. Careful not to cut into the threads to deep on the other side. Remove the pie with channel locks and a chisel. Using the chisel and a hammer, crush the remainder of the cap inward to release the threads. At this point you should almost be able to spin it out by hand.
I am a plumber and do this weekly, it takes me about 20min. Replacements can be found at a hareware store or your local plumbing supply house. Expansion plugs aren't bad either.

Another woman here! (a teacher) I had a tree planted on our playground so the kids would have some shade at PE. I need to give it a deep watering once a week, there are two PVC pipes from the root ball to about 12 inches above the soil surface. There's a PVC cap on the end of each pipe, no glue, no threads, which I need to get off about once a week. Someone keeps tapping down the caps and I can't get them off. Any ideas would be really helpful. Thank you.

I used a 2ft Crescent wrench on the protruding square that's for putting the wrench on. It just ripped the square off, and made a hole in the plug. I broke the rest of the plug out with a hammer and chisel.

Now I hope to find a replacement.
