About 4 years ago i was sitting in my bedroom and heard a loud scratching noise in a closet. There is a plumbing access panel for the shower in the closet. It turns out, a rat or a something had scrached a hole in the shower drain pipe and that allowed water to drain directly on the ground
. I had a home warranty but they did not cover damage from rodents. When the pipe was changed out i asked the plumber if he had a metal pipe and he told me they only carried the pvc on the truck. He told my i could go pick one up at lowes but i did not know what to look for and that would have added time onto the bill.

About 2 months ago i looked at the pipe and it has more scratches in it from something.

I would like to have it replace with a metal pipe.
How much would that cost?
