Sprinkler blowout booking is closed for the season. Bookings reopen September 1. Use the form to request startup or repair, or call us to be added to the fall waitlist.
Why sprinkler blowouts matter
Southern Alberta winters freeze irrigation lines hard. Any water left in poly pipe, brass valves, or the backflow assembly can expand, split, and crack — and the damage is not visible until you turn the system on in spring.
A proper blowout uses a truck-mounted compressor with the right CFM for the system, not a small portable unit. We work zone by zone, watch each head, and drain the backflow at the end.

Sprinkler blowout questions
When should I book a sprinkler blowout in Medicine Hat?
Book before the first hard freeze — typically mid-September through late October in southern Alberta. Earlier bookings get earlier slots; the last week of October fills up quickly.
What happens if I skip the blowout?
Water left in heads, valves, and the backflow assembly can freeze and crack. Common damage includes split poly lines, broken brass valves, and ruptured backflows — all far more expensive than a blowout.
How long does a residential blowout take?
Most residential systems take 30–60 minutes. Larger or multi-zone systems take longer. We work zone-by-zone with calibrated airflow to clear every line without damaging heads.
Do you blow out commercial systems too?
Yes. We blow out commercial irrigation across the Medicine Hat area — strata complexes, churches, schools, and commercial properties. Larger sites are quoted by zone count and access.
What size compressor do you use?
We use truck-mounted commercial compressors sized to the system, not a small portable unit. Proper CFM is what actually clears the lines without overpressuring heads.
