A sprinkler visit should leave you with more than a new timer setting. You should understand which parts of the garden are being watered, what needs repair, and how the system will be managed as the season changes.
Begin with each watering zone
Before booking a service, make a short list of what you have noticed: a persistently wet corner, a dry strip beside the path, spray reaching the windows, or a controller nobody feels confident adjusting. Photographs and a rough garden sketch can help explain the pattern. Describe the symptoms without deciding which component must be replaced.
Ask whether the visit includes observing every zone while it operates. A price for a controller adjustment may cover a different service from a complete system inspection. Have the contractor explain how they will record findings and whether you will receive a repair proposal before additional work begins.
The EPA’s Sprinkler Spruce-Up guidance identifies damaged or tilted heads, leaking connections, and spray directed onto paving as problems worth checking. It also notes that pooling between watering cycles can indicate an underground leak. These are reasons to investigate, not enough information for a homeowner to diagnose a buried pipe.
Ask for findings you can act on
A useful assessment separates the observed problem from the proposed solution. If the recommendation is to replace several heads, ask which ones, what is wrong with them, and why the proposed replacements suit that area. If the contractor recommends more extensive work, request a clear boundary between today’s repair and a future redesign.
Use a short written scope to compare visits and quotations. The following questions can help make an unfamiliar service easier to understand:
| Part of the visit | What to clarify |
|---|---|
| System inspection | Which zones and components will be checked, and how will findings be recorded? |
| Repairs | What is included in the visit price, and what requires separate approval? |
| Coverage | Where is water missing the intended area or reaching paving? |
| Controls | Which settings or devices will change, and why? |
| Follow-up | What will be rechecked, when, and at what additional cost? |
Ask the contractor to demonstrate the affected zones after approved repairs. Keep unresolved observations on the written record, with an agreed next step. A tidy invoice is more useful when it identifies what was actually checked and changed.
Choose controls with a purpose
A new controller should answer a specific need. The EPA distinguishes two WaterSense-labeled controller types: weather-based models use weather and landscape information to tailor schedules, while soil-moisture-based models use soil readings to prevent unnecessary watering. Neither description tells you whether a particular product is the right choice for your existing system.
Ask the installer to explain the proposed model, its compatibility, and the settings they will establish for your garden. If an app or connected service is involved, clarify who owns the account, what happens if the connection is lost, and whether any ongoing charge applies. Request a demonstration of normal operation and the pause or override controls.
Keep the equipment discussion connected to the inspection findings. Ask what the controller change will address and which repair or coverage issues still require separate attention. Avoid accepting a promised saving without understanding how it was estimated for your property.
Plan for the next season
There is no single watering schedule to copy into every garden. The EPA’s watering guidance recommends seasonal adjustments and consulting the local water utility about when and how much to water. Ask the contractor to explain the starting schedule in terms of your plants and site, and how local watering restrictions will be accommodated.
EPA also describes professional irrigation services as including design, installation, maintenance, and auditing. Ask which of those services you are buying and what relevant training the person doing the work has. Discuss whether your climate calls for winterization and who will handle it; do not assume a general tune-up includes seasonal shutdown or restart.
Ask for a labeled zone list, the controller model, a record of completed repairs, the agreed settings, and a contact for follow-up. These make the next service visit easier to brief and help another household member understand the controls.
