Soil and Climate
Many Kingwood yards are shaded by mature trees, and soils vary from one neighborhood to the next. To see what’s under your own yard, look up your address in the USDA Web Soil Survey. In wooded yards, roots can crowd or crack shallow lines and leaf litter can block nozzles, so it pays to walk each zone while it runs.
This area is in USDA hardiness zone 9b, where the coldest night of a typical year reaches 25–30°F (USDA Plant Hardiness Zone Map). Freezes are rare, but they happen. During the February 2021 winter storm, the City of Houston fell to 13°F, and the National Weather Service reported broken pipes across the region (NWS Houston/Galveston). Backflow preventers and exposed pipe above ground are the sprinkler parts most likely to crack. If yours sprays or drips after a freeze, see backflow preventer leaking.
Problems Kingwood Conditions Make More Likely
- Broken or clogged heads under trees and in beds
- Pipe leaks near tree roots
- Dry spots where shade, roots and coverage gaps meet
- Zones that won’t turn on in older systems
- Backflow preventer leaks after a freeze
Hiring Someone in Texas
Texas licenses landscape irrigators at the state level. Under Texas Occupations Code Chapter 1903, anyone who installs, repairs or services an irrigation system for pay generally needs a state irrigator license, or must work under a licensed irrigator. A homeowner working on their own property is exempt. Ask any contractor for their license number and check it with the state (license information).
Texas rules also require backflow protection on irrigation systems connected to drinking water (30 TAC 344.50). If your backflow device is leaking or was damaged, have a licensed professional repair it rather than taking it apart yourself.
