A converted front yard is a billboard the neighbors genuinely study
Turf removal put the plumbing side of landscape work in public view, and curiosity travels down a block faster than any ad.
When grass comes out, the irrigation under it has to be rethought. Spray lines get converted to drip, zones get abandoned, valves and backflow get reworked, and a hose bib nobody could reach becomes a problem.
Homeowners think of all of that as landscaping until somebody explains it is plumbing. A short before and after that names the plumbing part is the single most useful post a valley shop can make.
The interesting half is exposed for one afternoon. Whoever caps the old zone should film the manifold and the valve box before the gravel goes back down, because after that the entire job is invisible again and no later visit can recover it.
The proof of a conversion arrives on a later bill rather than in the yard. Gravel goes down and the job looks finished, but whether the new drip zones were set correctly does not show up until a cycle has run, so film the controller with the zone times on the screen. It is the only record of what you actually programmed, and it is the first thing anybody asks about when the number does not move.
