Irrigation Blow-Outs & Spring Start-Ups
Clear the lines before the freeze. Start clean in spring.
Expert Irrigation Blow-Outs & Spring Start-Ups
Most Treasure Valley homes run a pressurized irrigation system. Water left in those lines over winter freezes, expands, and cracks pipe, valves, and the backflow assembly.
In the fall, we blow out the system with compressed air. In the spring, we bring it back online, check for leaks, and make sure the backflow assembly is working.
When to schedule
- Irrigation water is shut off for the season
- The first hard freeze is coming
- Irrigation water is turned back on in spring
- You see leaks or soggy spots at start-up
- The backflow assembly is cracked or leaking

Irrigation Blow-Outs & Spring Start-Ups Questions, Answered
Straight answers from local plumbers who've been working in Nampa and the Treasure Valley since 1960.
When should I blow out my sprinkler system?
+
After your irrigation water is shut off for the season and before the first hard freeze.
Can I just drain the system instead?
+
Some systems have drain valves, but gravity leaves water behind in low spots. Compressed air clears the lines more completely.
What happens if I skip the blow-out?
+
Water left in the lines can freeze and crack pipe, valves, and the backflow assembly. The damage usually shows up as leaks in spring.
What's included in a spring start-up?
+
We bring the system back up to pressure slowly, check the backflow assembly, look for leaks, and run each zone.
Do you repair sprinkler heads and buried sprinkler lines?
+
We handle the plumbing side: the blow-out, the start-up, the backflow assembly, and the connection to your home. For buried sprinkler line and head repair, we're happy to refer an irrigation specialist we trust.
Should my backflow assembly be tested at start-up?
+
Spring is a good time to test. Many water providers require an annual test, and we can handle it during the same visit.
