Where to LOOK to find old drain pipes when buying a home

Rusted drain pipes are typically visible by looking down a shower drain. Drain pipes are located beneath the surface and are not exposed to view from the top. Rusting in drain pipes usually occurs over time due to moisture exposure, and the effects are not visible without disassembling or inspecting the plumbing system.

If you suspect rust or corrosion in your drain pipes, it's best to consult a professional plumber. They can assess the condition of your plumbing and take appropriate measures to repair or replace any corroded pipes as needed. Attempting to address plumbing issues without the necessary expertise can lead to further damage or problems, so it's advisable to seek professional assistance.
