Spring Irrigation in Brentwood: Restarting Your System the Right Way

When to turn your sprinklers back on

There is no single date for spring irrigation in Brentwood, but there is a sensible rule: wait until the risk of hard overnight freezes has passed, and turn the system on before the lawn actually needs it. Spring rain often covers early weeks, and a system that is ready and tested gives you options when the first dry, warm stretch arrives.

Restarting too early means pressurized pipes and a charged backflow preventer exposed to a late cold snap. Waiting too long means discovering a broken zone in the middle of a dry spell, during the busiest weeks for irrigation companies. The practical middle ground is to book the startup early and schedule the visit once freezing nights are behind you.

Many Brentwood homeowners lock in a spring startup when their system is winterized in the fall, which takes the guesswork out entirely.

If you plan to run the system yourself first, open the supply slowly rather than all at once. A sudden rush of water into empty pipes can create pressure surges that stress fittings, especially ones that already took a beating from winter. Run each zone for a few minutes and watch it before setting any automatic schedule.

Why winter leaves work to do

Even a well-winterized system comes out of winter changed. Months of freeze-thaw cycles, soil movement and dormancy can leave:

• Shifted heads. Clay soil heaves and settles, tilting heads so they spray the sidewalk or the house.
• Cracked fittings. Small cracks that did not leak when empty may leak once pressurized.
• Clogged nozzles. Soil and debris settle in heads and screens over the off-season.
• An uninspected backflow preventer. The device has not been looked at since the end of last season.
• A stale controller program. Last summer's schedule, or the off setting from fall, is not right for spring.

Brentwood's rolling lots, mature trees and multi-zone systems make these issues more likely, simply because there is more pipe and more heads for winter to disturb.

What a professional startup checks

A complete spring activation goes zone by zone, not just valve on and done. Aqueduct lists these steps on its spring irrigation startup page:

• Zone-by-zone inspection with every head checked and adjusted
• Controller programming updated for a spring watering schedule
• System pressure check to find leaks before they damage the lawn
• Backflow preventer inspection to confirm winter did not cause damage
• Sprinkler head adjustment to optimize coverage and eliminate dry spots
• Minor repairs noted and quoted on-site if the homeowner is present
• A written audit report provided with the invoice

That report is the part to keep. It gives you a record of where the system stands going into the season and a list of anything that needs attention.

Common post-winter problems and what they look like

If you restart on your own or notice something after a startup, here is how typical problems show up:

• A soggy patch or bubbling water with the system running usually means a cracked lateral or main line.
• A zone that will not shut off often points to a valve diaphragm or debris in the valve.
• A zone that will not turn on can be wiring, a controller setting or a failed solenoid.
• Weak, misty spray suggests low pressure from a leak elsewhere, or clogged nozzles.
• Dry rings or brown strips in the lawn mean coverage gaps from tilted or blocked heads.
• Water around the backflow preventer needs attention before the system runs regularly.

Catching these early is the whole point. A leak found at startup costs a fitting; a leak found in July can cost turf, plants and a big water bill.

Some issues hide until summer demand rises. A zone that seems fine on a cool spring morning may show weak coverage in the heat, when evaporation and longer run times expose gaps. That is another reason to keep the startup audit report and recheck the zones it flagged once temperatures climb.

Trees are another Brentwood-specific factor. Mature roots can lift or crush lines over time, and spring growth in shrubs and perennials can block heads that had clear spray patterns last fall. A startup is a good time to move or raise heads that plantings have outgrown.

What to expect when you book

With Aqueduct, the process is straightforward. You submit a request and someone from the team calls within about one business day to confirm details and lock in an appointment. You get an email reminder the day before. The technician performs the full activation, and if minor repairs are needed, provides a quote on the spot and can often finish the work the same day with your approval. Larger repairs are quoted and scheduled separately. The audit report arrives by email with the invoice.

Aqueduct sends its own technicians rather than subcontractors, and with low turnover, customers often see the same technician year after year. It serves Davidson, Williamson, Sumner and Cheatham counties, including Brentwood.

Questions to ask any spring startup service

Whoever you hire, a few questions tell you whether you are getting a real inspection or a quick turn of the valve:

1. Will every zone and every head be checked? A startup that only runs the controller through its cycle from the garage misses most problems.
2. Is the backflow preventer inspected? It sits exposed all winter and is one of the most important components in the system.
3. Will the controller be reprogrammed for spring? Leaving last summer's schedule in place wastes water in a wet April.
4. How are repairs handled? Ask whether minor fixes can be done the same day and how larger repairs are quoted.
5. What do I get in writing? A written report gives you a baseline for the season and a record to compare against next year.
6. Who will do the work? Ask whether technicians are employees or subcontractors, and whether they are licensed, bonded and insured.

Clear answers to these questions are a better guide than price alone, because a missed leak or a mis-set controller usually costs more over a season than the visit itself.
