Sprinkler Repair in Preston Hollow

Preston Hollow lots are big, and so are the irrigation systems. More zones, longer pipe runs and more places for a small problem to hide. We find it and fix it.

Big systems, hidden leaks

On a large lot, the main line from the shut-off to the valves can run a long way across the property. A crack in that line leaks all the time, even when no zone is running, and on a big lot the water may surface far from the break or not at all. A jump in the water bill is often the first sign. We isolate sections of the system and watch the water meter to narrow it down before we dig.

Many zones, sometimes more than one controller

It is common to find 20 or more zones here, sometimes split between two controllers, or with separate systems for the front, back, pool area and gate entry. Zones get mislabeled over the years. We test each one, label it on the controller, and give you a simple zone map.

Getting the schedule right

With that many zones, the total run time adds up. If nobody plans the schedule, zones end up running past 10 a.m., which loses water to evaporation and breaks the Dallas rule against sprinkler watering from 10 a.m. to 6 p.m. We build a schedule that fits every zone into the allowed window and set lawn zones to cycle and soak so the clay takes the water instead of shedding it.

Smart controllers on large properties

A smart controller can cut a lot of water on a big property, but only when every zone is set up with the right head type, plant type, sun and slope. A smart controller with default settings often waters as much as an old timer. We set them up zone by zone.

Gated entries, drives and estates

Heads along long driveways, motor courts and entry gates take hits from cars and service vehicles. We use sturdier heads in those spots and set them to keep water off the drive. For larger estates with property managers, we can work through the manager and send a written report.

Dallas rules apply

Preston Hollow is inside the City of Dallas, so Dallas rules apply. Sprinklers can run no more than twice a week: Sunday and Thursday for even-numbered addresses, Wednesday and Saturday for odd. Nothing on Monday, Tuesday or Friday. And no sprinkler watering from 10 a.m. to 6 p.m. on any day of the year; Dallas made that daytime ban year-round in 2026. Hand watering, soaker hoses and drip are allowed any day and any time. Read the City of Dallas ordinance summary.

Spraying into the street and running during rain can also bring a notice. Read more in our plain-language guide to the watering rules.

Questions people ask us

Can you handle a system with 30 zones?

Yes. Large systems just take more time to test. We will plan the visit around the size of the system.

How do I know if I have a main line leak?

Turn all zones off and look at your water meter. If the leak indicator is still moving with every faucet in the house off, there is a leak somewhere. If it stops when you close the irrigation shut-off, the leak is on the sprinkler system.

Do you work with property managers?

Yes. We can schedule through your manager and send photos and a written summary.
