The best time of day to water a lawn is early morning or evenings - the cooler times of the day. Steer clear of watering during peak warmth and sun activity; not only can it be potentially damaging to plants, but more water is lost from evaporation, reducing efficiency.
Will a sprinkler system use less water than manual watering?
Provided the pressure and flow are identical, and the length of time watering is equal, there should be no difference in in the amount of water delivered between manual or timed sprinkler systems. It’s all about pressure and flow that determines delivery amount.
How frequently should a lawn be watered?
In the warmer months you want to water three to five times a week. In cooler months, two to three times a week should be plenty. The goal is to get ¾ of an inch to 1 inch of water delivered each time. A good rule of thumb is a little more in summer, a little less in winter. If you live in a rainy area, you might not need to manually water at all in the winter.
What is a check valve?
A check valve is a valve that only allows flow in one direction, while preventing flow in the opposite direction.
How long should sprinklers be operated, per day?
The first variable to determining how long to run your sprinklers is seasonal; the second is sprinkler output. In warmer months, or peak growing season, water for approximately 20-30 minutes a day, every three to five days. Ideally your grass wants 3/4 of an inch to 1 inch of water. In the cooler, slower growing seasons, 10-15 minutes, two to three times per week. If you use automatic sprinklers, be sure to adjust them seasonally.
