Sprinkler spring start-up in Salt Lake City

Turning a sprinkler system back on is not a matter of opening the valve. Do that and you send a pressure wave through pipe that has been empty for five months — which is how a system survives winter and then breaks in April.

When to bring the system back online

April into May, once the risk of a hard overnight freeze has passed. Turning on too early means a cold snap can refill and crack the lines you just protected all winter.

There is no rush on the lawn side. Cool spring soil holds moisture, and grass coming out of dormancy needs far less water than the same lawn in July. Starting a week late costs nothing; starting three weeks early can cost a repair.

Why the valve gets opened slowly

An empty irrigation line filled at full pressure produces water hammer — a shock wave that hits every fitting, valve and head at once. The pipe survived winter because it was empty; this is the moment it is most likely to fail.

Opening the main slowly lets the system fill and purge air gradually. It takes a few extra minutes and it is the single most important step of the whole visit.

What a spring start-up includes

  • Slow pressurization of the mainline, with air purged zone by zone.
  • A head-by-head inspection. Every head is run and watched — sunken, tilted, cracked or blocked ones get found now rather than in July.
  • Nozzle cleaning and adjustment. Arcs and radii reset so the coverage overlaps the way it was designed to.
  • Zone-by-zone pressure and coverage check. Misting heads mean pressure is too high; weak throw means it is too low or something is restricting flow.
  • Leak detection across the mainline and laterals, while the ground is still soft enough to show it.
  • Controller programming matched to spring, not left on last August’s schedule.

You get a plain-language summary of anything worth fixing, with no obligation to fix it that day.

What we look for after a Utah winter

Spring start-up is the annual inspection whether you treat it that way or not, because a system that was not fully blown out in the fall shows its cracks the moment it is pressurized.

  • Water weeping from the base of a head — a split riser or body
  • A zone that will not pressurize — usually a cracked lateral underground
  • Dripping or spraying at the backflow assembly — the most common freeze casualty
  • A zone that will not start at all — a solenoid that cracked, or a wire broken by ground movement

Anything found gets diagnosed on the spot. If it needs work, that becomes a repair visit with a quote before anything is touched.

Questions we get asked

What does a seasonal tune-up include?

A head-by-head inspection, nozzle cleaning and adjustment, a zone-by-zone pressure and coverage check, leak detection, and controller programming matched to the season. You get a plain-language summary of anything worth fixing.

My system was winterized. Do I still need a start-up?

A blowout protects the system; it does not verify it. Bringing the system online slowly and walking every zone is what catches the damage that did happen, and resets the coverage that drifted last season.

Can you reprogram my controller for the season?

Yes, and it is part of the visit. Spring run times are considerably shorter than midsummer ones — leaving last August’s schedule running through April wastes water and does the lawn no favours.

What if you find something broken?

You get told what it is, what it will cost, and what happens if it waits. Every job starts with a free estimate and nothing gets fixed without your go-ahead.
