Why does my sprinkler head not spray far enough?
Short answer: Most often because the nozzle is running below its design pressure. A nozzle operating below its intended pressure may not achieve its designed spray radius.
Every nozzle is built to throw a set distance at a set pressure. A spray nozzle rated for 15 feet at 30 PSI will fall short of that distance if it is only getting 20 PSI — the spray comes out weak, drops early, and leaves the far part of its pattern dry. The head looks like it is working, but the coverage is not reaching where it should.
Low pressure at the head can come from a lot of places: too many heads or oversized nozzles on the zone, a leak in the lateral, a valve that is not fully open, a clogged nozzle, or friction loss through a long run of undersized pipe. A clogged nozzle can also look like a pressure problem, since a blocked nozzle throws short even when the pressure is fine.
That is why we test the zone instead of guessing. We check the pressure at the head, look at the nozzle, and check the rest of the zone. If the pressure is low everywhere on the zone, the cause is upstream. If only one head is short, the cause is usually that head or its nozzle.
What we check in New Caney
We run the zone and measure how far each head actually throws against what its nozzle is rated for. We check the pressure at the head, the nozzle for clogs or damage, and the zone for the upstream causes of low pressure. The fix follows the test — a cleaned or replaced nozzle, or a zone pressure problem corrected at its source.

Frequently asked questions
Can I fix a short throw by turning up the water?
There is no volume knob on a sprinkler zone. Throw is set by the pressure at the head and the nozzle, so the fix is finding why the pressure is low or why the nozzle is not performing.
Is a short throw the same as low pressure?
Often, but not always. A clogged or damaged nozzle can throw short on a zone with good pressure. We check the nozzle and the pressure together so we fix the right thing.
