Start with conditions, not a product
A proper diagnosis works through fixture behavior, pipe material, current pressure and drainage, venting, where the shutoffs are, access, and any prior repairs.
Build a complete scope
- Current condition and probable cause
- Prep and protection for the work area
- Material selection and how it will be installed
- Permit needs, testing, cleanup, and restoration
- Exclusions, warranty, and how changes get approved
Johns Creek context
The build era is the most useful thing a plumber can know about a Johns Creek house. Homes from the late 1970s through the mid 1990s may carry polybutylene supply piping, which fails at its fittings, often without warning, and is worth identifying before it announces itself -- while copper of the same period is now old enough for pinhole leaks and worn valves to be routine. Size is the second factor: in tall houses with long runs and multiple bath groups, pressure and recirculation problems are common, and a failing pressure-reducing valve at the entry explains a surprising share of complaints upstairs. The third is location. Water heaters in these houses are frequently in attic space or over finished rooms, which turns an ordinary end-of-life failure into a ceiling repair, so the pan, the drain line and the age of the unit are worth checking before that happens.
