Short answer: Residential plumbing covers the same core services — repair, drain cleaning, replacement, and installation — viewed specifically through the needs of an owner-occupied home rather than one isolated fixture.
Homeowners often deal with plumbing issues that touch more than one part of the house at once, or that come up during a home purchase, a remodel, or after years without a plumbing check. This hub frames the core services around that whole-home perspective.
Each page below links back to the more detailed version of the same service where useful.
