Late February is a good time to turn your sprinklers on and check them for possible breaks, clogged sprinklers, and any other issues. Your system will then be ready for Spring start-up in mid-March.
When should I turn my sprinkler system off?
Usually around Thanksgiving, we start getting our seasonal rains. This would be the best time to turn off your system, so as not to overwater your yard. If it is a dry winter, you will need to reduce the watering time and days accordingly. Rule of thumb is, during the winter season, 3 days a weeks is more than plenty.
We recommend watering in multiple sessions. Example: Instead of watering your yard for 15 minutes straight, break it up into 3 to 5 minutes sessions, with a 1-2 hour soak time in between. This will promote fewer run-offs and will encourage deeper root growth.
We also recommend not watering on a daily basis; allowing roots to breath. Example: Monday, Wednesday, Friday and one day on the weekend. We suggest watering your grass in the early evening from 7:00 p.m. to 10:00 p.m. or early morning hours from 3:00 a.m. to 7:00 a.m.
Please note that this does not apply to new landscaping, annuals, and new plantings.
Drip Irrigation has become extremely popular. This allows you to water shrubs and flowers more efficiently. Drip Emitters put water at the base of the plant to soak into the root base where it is needed, rather than on top of it. Emitters put out a regulated drip that can be changed to meet the needs of various plants. A 2' shrub needs less water than a 20' tree.
Rain sensors turn the system off, if it is raining or has been raining, for an extended period. This saves on your water bill and saves your landscaping from drowning. Too much water is just as bad as not enough!
What is a backflow preventer?
A backflow preventer is a device that prevents outdoor water that has been contaminated by landscape fertilizers and pesticide chemicals from syphoning back into your home water supply.
Do I have to be present for repairs?
How do I program my controller?
If the irrigation valves are located below ground in a box, what you need to look for is a PVB (pressure vacuum breaker), (see photos 3 and 4 below). These are usually located in the front yard where your water line comes from the ground and in to the house, but in some cases it may be installed behind shrubs, so you'll have to look through your landscaping to find it. They are usually about 12" to 18" above the ground. Once you have located it, it will have two valves. Either valve will shut the system off; turn it clockwise until water flow has stopped.
