Seasonal Activation & Inspection
Your system’s been sitting dormant since fall, and there’s no way to know what shape it’s in until the water’s back on. Pacific Lawn Sprinklers activates, tests, and adjusts every zone before your lawn starts depending on it.
A spring sprinkler system start-up is the process of safely reactivating, inspecting, testing, and programming an irrigation system after its winter shutdown. Pacific Lawn Sprinklers provides professional spring start-up services to identify potential problems and prepare your system for the watering season.
This service is recommended for anyone whose system was winterized before freezing temperatures arrived, and it’s especially useful for homeowners who recently purchased a home with an existing irrigation system and don’t know its history or condition.
Skipping a professional start-up can leave your system vulnerable from day one. Many irrigation problems begin underground and may not be visible to an untrained eye. Our technicians use specialized testing tools to check each zone for proper pressure and flow, valve operation, hidden leaks, and electrical issues. Catching these problems early can help prevent water waste, system damage, and more costly repairs later in the season.
Turning your system back on after winter takes more than opening a valve. Our technicians gradually restore water pressure, activate your controller, and walk every zone individually to confirm coverage, pressure, and performance before your lawn needs it.
If we find an issue along the way, we’ll explain what we found and walk through your options before any repair work begins. Service availability may vary by location.
We reseal plugs and drain valves left open from winterization, so nothing leaks the moment water starts flowing again.
Water is restored gradually to avoid water hammer, while we check mainlines, the backflow preventer, and the valve manifold for winter damage.
We power up the controller, then activate each zone individually, checking coverage, pressure, and every electronic component that keeps your system running correctly.
If we find an issue, we’ll explain it and quote it before doing any work, completed the same visit when possible.
Your controller gets seasonal settings and a fresh backup battery, then we recheck the whole system to confirm it’s ready.
Annual backflow testing is available on request as an optional add-on, performed by our state-certified technicians.
Spring start-up covers all ten points below, whether or not repairs are needed along the way.
Spring start-up gets your system running again, but winterization is what protects it once the season turns, and most homeowners need both every year. Ask your local team about a recurring maintenance agreement, so your winterization is already on the calendar and you’re not starting from scratch next spring.
With more than 45 years of irrigation experience, Pacific Lawn Sprinklers makes seasonal activation simple. Our technicians don’t just turn your water back on, they confirm your system’s actually ready, and if it isn’t, our repair team can usually fix it the same visit.
Opening a valve too fast is the most common mistake in a DIY start-up. Our technicians restore water gradually every time, protecting pipes and heads that a rushed reactivation could damage.
When your area requires it, our technicians are state-certified to test and document your backflow preventer, so you’re covered without hiring a second company.
If we find a problem during your start-up, we’re equipped to fix most issues on the spot instead of scheduling you for a second appointment.
We show up when we say we will, or your visit comes with a guarantee, so a busy spring schedule doesn’t mean waiting around.
A lawn sprinkler system activation typically costs between $90 and $150, depending on the size and complexity of the system. Repairs, alterations, and additional services are not included in the base price but may be completed during the same visit when possible.
More than 10,000 homeowners across our service areas have shared their experience with Pacific Lawn Sprinklers over 45 years of service. Here is what they are saying.
I wish I had know about Pacific Sprinklers years ago for my residential and commercial properties! Not only are they friendly professional and reasonable, they can fix everything perfectly and timely. They are THE BEST.
You can open sprinkler valves yourself, but that’s exactly how most water hammer damage happens, opening too fast causes a pressure surge that can crack pipes and heads. If you’re looking into how to open a sprinkler system on your own, the safe version is: gradually, one zone at a time, with everything checked afterward, which is what a professional start-up does for you.
Your technician will explain what was found and discuss the recommended solution with you before completing additional work. You’ll receive a detailed quote for proposed repairs or alterations. Depending on the extent of the work, repairs may be completed during the same appointment or scheduled for a follow-up visit.
