Sprinkler Start-Up & Activation for Lower Mission Properties
Turning the water back on is the easy part. Doing it slowly enough not to damage cold, empty pipe, then testing every zone before you rely on it, is the actual job.
On established systems, start-up is the natural moment for the tune-up that older hardware needs anyway. Heads that have settled, nozzles that have worn and a controller still running last year's programme all surface in the same visit.

Commonly requested here
Spring start-up work on Lower Mission properties
- Raising and levelling heads that have settled below grade
- Replacing worn nozzles found during zone testing
- Testing valves that may have seized over winter
- Replacing controller backup batteries and reprogramming
- Adjusting arcs after a season of landscape growth
Worth knowing
Older mechanical controllers often lose programming when their backup battery fails over winter. Replacing the battery at start-up prevents the schedule vanishing again mid-season.
Issues that come up in Lower Mission
- Overwatering on flat, moisture-retentive ground producing shallow roots and thatch
- Older mechanical controllers with no rain shut-off in a neighbourhood with real conservation expectations
- Landscape renovations leaving heads stranded in beds or buried under new hardscape
Local context
- Lower Mission's proximity to Okanagan Lake and its beaches means flat, deep soils that hold moisture longer than benchland properties.
- Mission Creek runs through the area, and nearby properties can sit on ground with a seasonally higher water table.
- The neighbourhood's high renovation rate means irrigation zones frequently no longer match current planting layouts.
Proximity to the lake moderates temperature slightly and the flat, deep soil retains moisture well, so Lower Mission properties usually need less frequent watering than the benches above them.
What to expect
Typically part of the job
- Adjusting arcs after a season of landscape growth
- Replacing controller backup batteries and reprogramming
- Testing valves that may have seized over winter
- Head cleaning, levelling and arc adjustment
- Leak and damage check across heads, valves and visible pipe
- Zone-by-zone operating test and visual inspection
Scope varies between contractors. Use this as a baseline when comparing quotes, and ask what is included before agreeing to work.
Questions
Spring start-up in Lower Mission
Can I start the system up myself?
You can, and the critical part is doing it slowly. Open the main valve only partway and let the system fill gradually rather than all at once — a fast surge into empty pipe is what breaks things. Then run each zone individually and watch it, checking for heads that do not rise, unexpected pooling and any drop in pressure. If anything looks wrong, stop and have it looked at before running the full schedule.
When should spring start-up happen?
Once the risk of hard overnight frost has genuinely passed and the ground has thawed — in the Central Okanagan valley that is usually somewhere in April, though it varies by year and by elevation. Starting up while pipe is still frozen risks cracking it. Higher-elevation properties need to wait considerably longer than valley-floor ones.
One zone weeps even when the system is off. What is that?
Almost always a valve rather than a pipe. A worn diaphragm or debris on the seat stops a valve sealing completely, so a small amount of water keeps passing to that zone. On systems of Lower Mission's typical age it is a routine repair — a rebuild kit or valve replacement — and worth addressing promptly since it runs continuously.
How often should a Lower Mission lawn actually be watered?
Less often than most schedules assume, and deeper each time. On flat, deep, moisture-retentive Lower Mission soil, frequent short cycles encourage shallow roots and thatch. Fewer, longer waterings drive roots down and produce more drought-resilient turf. Your purveyor's current watering schedule sets the outer limit on frequency.
