How should I start up my sprinkler system in the spring to avoid problems?

Turn on the water slowly—just a quarter turn first—to let air and sediment ease out without blowing out frozen pipe fittings or heads. Then run each zone manually for a couple minutes, walk the yard, and check for broken heads, pooling water, or leaks. Fix any issues before setting the timer, and water early morning (4–6 AM) to reduce evaporation. A slow, careful startup now beats a soggy repair bill later.
