Info on Desert Crest Systems
There are a number of commonly asked questions about irrigation for landscaping in Phoenix and Scottsdale. To make it easy for you to get the answers anytime, we’ve posted the information right here. Naturally, if you live elsewhere in the Valley, the same information applies to your watering system too.
1. Can the water to the irrigation system be shut off without shutting off the water to the house?
Yes, in front by your hose bib (outdoor faucet) we have installed a vacuum breaker. On it are two shutoff levers, and either one will shut off the water to the irrigation system.
2. Does each zone need a start time?
No, start times only start programs. Every zone that has minutes set will run one after another with only one start time. For example, if the “start time” for program A is 6:00 a.m. and Zone 1 is set for 60 minutes and Zone 2 is set for 30 minutes, then program A Zone 1 will start at 6:00 a.m. and program A Zone 2 will start at 7:00 a.m.
3. There is a leak in my valve box, what should I do?
Leaks are usually caused by one of two things: a loose cap or a loose screw. To fix them, remove the filter cap and reset or try tightening the screws on top of the valve.
4. I don’t see any emitters. Do I have them on my drip system?
Yes, you do. The emitters we like to use are on the end of the tubing. They rarely clog and are very reliable. They are called MF emitters. It is common for the drip line to be under the granite to conserve water, yet thoroughly moisten root systems. After the drip system has run you should be able to see a damp area around the plant
5. Do all my plants get the same amount of water?
No, we use three different size emitters: 1/2 gph, 1 gph, and 2 to 10 gph (gallons per hour), depending on the plant requirement.
6. My clock is blank and nothing is working on it. What should I do?
Check these two items on your timer: the batteries and the power. If the battery fails during a power interruption, your program will be lost. When power is restored, the rain dial controller automatically defaults to its fail-safe mode. See your programming guide page 13 for more details. We recommend changing batteries at least once a year. It takes standard 9 volt batteries.
7. Will the batteries run my irrigation system?
No, the batteries only keep the controller from losing the programs if the power goes out.
8. How long will the batteries last?
About 1 year.
9. Why is my grass turning brown?
You need to make sure that you are watering your new lawn enough – about three times a day for the first 10 days or so. The soil beneath the new sod should remain “squishy wet”. Keep pet and foot traffic off the new lawn for at least 10 days. Do not mow the grass until at least 10 days after it was installed. After 30 days you may fertilize. If water is standing for longer than 48 hours, give us a call. Refer to the feeding and watering schedule in this packet as well.
10. Okay, the answer I need isn’t here!
