Why do rotary nozzles have filters?

Short answer: Their small internal passages need protection from debris that could interfere with the streams or rotation.
In plain terms, their small internal passages need protection from debris that could interfere with the streams or rotation.
Rotary nozzles water slowly on purpose — they put water down at a rate the soil can actually take in. That only works when pressure, spacing, and runtime are all set for the nozzle, not for a regular spray head.
Lawns around Humble deal with the same Houston heat and clay soil as the rest of the Lake Houston area, so a system that is close to right can still show problems here — dry spots in the sun, runoff on a slope, or heads that never quite throw far enough. That is why we test in the yard itself instead of guessing from the curb.

What we check in Humble

When we come out to a yard in Humble, we run the zone and watch each rotary nozzle — rotation, radius, and stream pattern — and check the pressure at the body, because rotary nozzles need their rated pressure to do their job. If something is off, we show you what we found before we change anything. See Sprinkler repair in Kingwood for what that visit covers.
