Spring startup in Lewisville is a walk, not a switch. After a freeze, heads stick, a valve weeps, and a lateral that split in January stays hidden until the first long cycle. The useful time to find that is before May 1, while a morning run is still allowed and the Bermuda has not filled in over a sunk head.
What the walk includes
Each station is run. Heads are raised or lowered to grade. Nozzles that fog or hit the street are changed. Valve boxes that heaved over the winter are set back down. The controller is put on the address days: Tuesday and Saturday for even addresses, Wednesday and Sunday for odd, Monday and Thursday for commercial, multifamily, and HOA. Start times stay outside 10 a.m. to 6 p.m. once that seasonal ban is in effect. The city’s current stage is checked on the outdoor watering page the same day, because a startup program written in March can be illegal by June.
A startup that finds a broken main is quoted before the trench is opened. The rest of the zones are still walked so the quote is the whole yard, not the first wet spot.
