Some home defects not worth fighting sellers over

Buyer seeks least-invasive fix for removing concrete from shower drain

DEAR BARRY: Ever since I bought my home, the shower has drained slowly. From time to time, I’ve had to use drain cleaner. But recently, it has gotten really bad, so I finally called a plumber. He said the drain is blocked with concrete and there is no way to get it out.

I called three other plumbers, but they said the same thing. The recommended repair involves tearing out the shower pan because the house is built on a concrete slab. My home inspector said nothing about this when I was buying the home, so I assume the previous owner used drain cleaner before the inspection.
