The builders of my home used a cheap plastic to cap, what I believe is, the clean out pipe for my kitchen sink. After 10 years the plastic has become brittle and completely broke away, leaving me with an exposed pipe and water flowing outside when the kitchen sink is on. My question is should I just place some sort temporary cap and seal it in place, or call a plumber out to rip out the brick and put on a proper cap? I have attached a picture and can provide more if need be.
