Water Discipline Package
This package adds a unionized 1" PRV (Caleffi 535 class) into a 1" copper irrigation downleg, then tests and tunes under flow. It’s one of the cleanest ways to establish pressure discipline—a core part of water discipline.
Properties with repeat pressure symptoms. If source pressure is high and failures keep returning, a serviceable downleg PRV install is usually a high-ROI first move.
| Patch Individual Failures | Install PRV Downleg Package |
|---|---|
| Repeat failures can continue | Pressure baseline is stabilized first |
| Misting/runoff often persists | Cleaner coverage tuning conditions |
| Future service can be invasive | Unionized layout supports maintainability |
| No shared pressure standard | Documented targets and follow-up workflow |
Why
Regulated pressure makes coverage tuning predictable and reduces stress on valves, heads, fittings, and splices.
Built For
Unionized hardware turns a PRV into a maintainable component instead of a permanent cut-in.
Scope Gate
We care about pressure under flow on your highest-demand zone—not only a no-flow gauge reading.
Confirm static pressure and observe behavior under flow with zones running.
Integrate a unionized PRV into the accessible downleg after backflow prevention.
Tune toward ~65 PSI discipline target with a regulated ceiling of 75 PSI.
Re-test zones under load and document settings for repeatable maintenance.
High source pressure is a repeat-failure multiplier. It increases misting waste, stresses valves and fittings, and makes coverage harder to tune consistently. A properly installed PRV gives us a stable working range so the system can be tuned like it should be.

Use measured zone GPM when available. Otherwise, start with an estimate and refine during the scope visit.
Defaults reflect common 1" irrigation supplies.
Optional: include backflow + fittings + piping loss.
Used only for pre-visit service-size estimates.
Illustrative: same zone, different pressures.
Every site is different, but the service-first goal is consistent: keep the PRV accessible, union-serviceable, and easy to test under flow.
This is a living package page. We update scope language and included options as common field configurations (and best practices) evolve.
We’ll measure pressure at the source and under flow, confirm peak zone demand, and recommend the cleanest install point for serviceability.

Typically in the irrigation downleg after the backflow prevention assembly, where it stays accessible, union-serviceable, and easy to test under flow.
Our discipline target is ~65 PSI, then we tune only as needed for operational performance. The new ceiling is 75 PSI so the system operates in a regulated, maintainable range.
Regulation reduces misting and stress, and it often enables better tuning and shorter runtimes. The best savings usually come after regulation when we can tune coverage and programming predictably.
This package is not a backflow replacement. If the device is failing, that is scoped separately and may be regulated depending on jurisdiction.
No. Static pressure is only one input. We verify pressure under flow on active zones because dynamic behavior drives real performance and failure risk.
Yes. Pressure control often reduces component stress, which is a common driver of repeat head, fitting, and valve failures.
Not always, but it is preferred where possible because unions improve service access and reduce maintenance disruption later.
Yes. Many properties phase work by ROI: pressure discipline first, then coverage/nozzle corrections, then control-layer upgrades.
