Getting Your Sprinkler System Ready for Winter in Cypress, TX
As temperatures cool around Fairfield, Cypress TX, St. Augustine and other warm-season grasses slow down and need less water than they did in summer. November is a practical time to review the sprinkler schedule, protect exposed parts of the system before a hard freeze, and check heads after leaves fall. This is general property-care guidance, not an irrigation repair service.
Cut back watering as the lawn slows
Texas A&M AgriLife notes that warm-season turf needs less water as days shorten and growth slows. Overwatering in cool, damp weather can encourage turf diseases such as large patch. When the lawn is no longer growing actively, many homeowners turn automatic irrigation off and water only during dry spells. Check your MUD or HOA watering rules before you change a schedule, because those requirements vary by neighborhood.
Adjust the controller and check sensors
Reduce the number of watering days or run times to match current conditions, and account for recent rain before a scheduled cycle runs. If your controller has a rain or freeze sensor, confirm it is unobstructed and still working. A seasonal-adjust setting, if available, can help you cut back without rewriting every zone.
Protect the backflow preventer before a freeze
Above-ground pipes, valves, and backflow preventers are the parts most likely to be damaged when water freezes and expands. Texas A&M’s School of Irrigation recommends turning the controller off, shutting off the water supply at the isolation valve near the meter or backflow assembly, insulating exposed PVC, and draining above-ground components such as the backflow preventer. Learn that shutoff and drain procedure before a freeze is forecast. Compressed-air “blow-out” methods are more common in colder climates, and most Texas systems are not designed for them; do not attempt that method without the right equipment and experience. If you are unsure how your system shuts off, a licensed irrigator can walk you through it.
Check heads after leaf season
Leaves and debris can block or tilt sprinkler heads and hide leaks. After leaf cleanup, walk the yard and look for heads that do not pop up, spray poorly, or sit under a pile of leaves. A brief test of each zone, on a day that is not freezing, can show problems early. We do not repair irrigation systems; if a head, valve, or backflow device needs work, a licensed irrigator is the right call.
Keep the rest of the yard on a seasonal schedule
Mowing and leaf work still matter in late fall. See our monthly lawn service schedule for how visits typically change through the year. Text your address to 281-746-6001 for a free estimate on mowing and related yard care.
