Slow the Flow: Residential Sprinkler Evaluations

We schedule appointments Monday through Friday 8:00AM-4:30PM, and appointments generally last 1-1.5 hours. All evaluations take place on-site at your property. You must have an in-ground sprinkler system that is turned on and in good working order at the time of the appointment.

Why haven't I heard back about an appointment time yet?

Hang tight! We likely don’t have appointments available in your area just yet, or we haven’t reached your name on our waitlist. Once we have appointment availability in your area, we will call, text, or email you to schedule your appointment. Look for email invites from “Slow the Flow” in your inbox.

What do I have to do to prepare for the appointment?

Make sure your system is on and is in generally good working order before the appointment. If your backflow preventer is not turned on or your system has major problems when we arrive, we will not be able to reschedule. Also, an adult (18 years or older) must be on the premises during the entire appointment, so please plan accordingly.

How long does the appointment take?

The entire appointment typically lasts an hour to an hour and a half for most residential properties. You (or another adult) need to be on the property for the duration of the appointment. However, while we strongly encourage you to engage in the entire evaluation, you are only required to meet with our associate for the first 10 minutes and last 10 minutes of the appointment.

Who are the associates performing the evaluations?

Our friendly team of trained associates is employed by Resource Central. They will have a Resource Central shirt and name tag and will announce themselves when they arrive at your home.

What does the evaluation involve?

Our associate will perform a visual inspection of all zones, making minor adjustments where they can and marking down any larger issues. They will then test certain zones to measure how much water the sprinklers put out and how evenly that water is distributed. By the end of the appointment, they will have an efficient watering schedule based off your specific system.

During this appointment can you help identify or fix leaks?

While our associates do look for obvious signs of a leak, our service is not for leak finding, and we cannot fix any leaks. We recommend finding a landscaper if you suspect you have a leak.
