Spring Sprinkler Start-Up in Denver: Prevent Leaks and Patchy Lawns

Spring is when a lot of Denver-area homeowners discover what winter did to their sprinkler system. Maybe a zone won’t turn on, a head is geysering, or your lawn is suddenly full of dry patches. The good news: most issues are common, fixable, and easier (and cheaper) to handle early—before you waste water all season.

Calaway Sprinklers helps homeowners with irrigation, leak repair, and timer install/replacement so your system runs smoothly when watering season starts.

A simple spring sprinkler start-up checklist
Use this quick checklist the first time you turn your system back on:

1) Turn water on slowly
Opening the water supply too fast can stress fittings and reveal weak points the hard way. Start slow, then listen for rushing water that continues longer than normal (often a sign of a leak).

2) Run one zone at a time and look for “obvious” problems
Walk each zone for 1–2 minutes and watch for:

  • Heads that don’t pop up
  • Heads spraying in the wrong direction
  • Misty spray (often pressure-related)
  • Water pooling near a head or valve box
  • One area flooded while another stays dry (coverage issue)

3) Check for leaks before they show up on your bill
A small leak can waste a surprising amount of water. Red flags include:

  • Constantly wet soil (even hours after a run)
  • Soft, sinking areas in the lawn
  • Water bubbling from the ground
  • A zone that seems to run “forever” or won’t shut off cleanly

Calaway Sprinklers offers prompt leak repair to keep systems operating properly.

4) Make sure your timer/controller is actually helping
If your sprinklers run at weird times, skip zones, or overwater after a weather change, the issue may be the timer/controller setup—or the controller itself. A modern, properly programmed timer can make watering more consistent and convenient.

Calaway Sprinklers provides timer install/replacement so homeowners can get better watering control.

5) Fix coverage issues before your lawn gets stressed
Patchy lawns aren’t always “bad grass”—they’re often a watering pattern issue:

  • A head is clogged or misaligned
  • Nozzles don’t match the area
  • A zone is underpowered due to a leak or valve issue
  • Plants or turf changed, but irrigation didn’t

Even small adjustments can dramatically improve how evenly your yard waters.

When to call a pro
DIY is fine for a quick nozzle clean or a visible head replacement. But it’s time to call for help if:

  • You suspect a buried line leak
  • A zone won’t shut off
  • Multiple zones have low pressure
  • The controller is unreliable
  • You want a more efficient setup (like drip irrigation for beds)

Calaway Sprinklers offers irrigation services, leak repair, and timer replacement for Denver-area homeowners.
