Sprinkler System Problem
I just moved into an old house that has a built in sprinkler system.
Unfortunately, one of the zones does not work, yet 2 of them do. By researching previous posts, I've found some good ideas on how to check if it is the wiring by hooking up the wires from a zone that works to one that doesn't and testing it that way. However, if it still does not work, apparently it is probably a valve problem. The thing is, I didn't know that each zone had a valve and I have no idea where a valve would be or what it would look like. I've looked everywhere near that zone for some sort of cutoff switch in the ground but can't find anything. I'll be calling a sprinkler repair man if necessary but I'm trying to avoid it. FOLLOW UP: For those with sytems... how long and how often should I water? I'm in Texas so the lawn requires frequent watering (I would think) but I'm also trying to keep my water bill at a REASONABLE level. Thanks! |

You really need to find the zone valves and operate them manually before troubleshooting the electrical. In any case the wire is probably open near the valve itself anyway. Start with where the hose hooks up and follow any pipes that don't lead into the house. The valves may or may not be buried but if they are they should be in an underground box with a lid at ground level it will be between the house and the sprinkler somewhere. If you really have no clue what they look like, go to HD and look at ones on the shelf. As for how much water you can ask your neighbors and the guys at the local hardware store or you can start with 20 minutes twice a week then check the lawn for signs of stress or success and adjust up or down as required. A successful lawn needs mowing once a week a stressed lawn has brown struggling spots. Individual sprinkler heads can be adjusted but I'll save that for later. |

Sprinkler System Problem
You want to water infrequently and deeply. Shallow watering every day
or two just encourages shallow roots, disease, and fungus. In summer, you will probably need to water every 4 to 7 days, depending on the soil, weather, etc. When you do water, it should get about 3/4 of an inch. An inch would be even better, but if you're paying for water it may not be worth it. You can tell when a lawn needs water by looking at it. It will start to take on a blue/gray appearance in spots, especially areas adjacent to the street, where it will be hotter, etc. Don't be afraid to let it start to show some stress. That's generally better than overwatering it. A lawn will even go dormant for a long time without water and revive when it rains. You want to water it in the early morning hours, when it's cooler and less likely to be windy, to minimize water loss. Time it so it will be done around 6AM. That will minimize the time it's wet. Worst practice is to water frequently and do it in the early evening. That leaves the lawn wet the longest. Also, leave fertilizing for Spring and most importantly Fall. |

This website has much more than you would ever wish to know about lawn irrigation: http://www.jessstryker.com/index.html This is what a valve looks like: http://www.irrigationtutorials.com/instal08.htm If you have done any digging, you might have cut a wire. Installing a new valve isn't too tough - figuring out what is wrong with one can be. Depending on the layout of your lawn, the valves might be all together at the beginning of the lines - I would start looking (if they are buried and not in a valve box) along a straight line from the timer to the first sprinkler head in the zone that doesn't work. We did hours and hours of searching for the three buried valves on our large condo lawn. With the last one, we ended up digging small holes every few feet along the supply line, then following line-of-sight to go along until we located the box. Wish I knew which dumbkoph buried them all ) |

As for watering, check out your county or state extension service
website. Optimum is usually l" of water a week, but in hot, dry areas that may be insanity. If you have no limitation on water, do it. Also, proper mowing technique can help conserve water by not cutting too short (dries out faster and impedes growth). Florida promotes turning lawn grass areas into xeriscapes and native plants to save on water; we also have reclaimed water. Warm season areas aren't the only ones trying to get away from chemicals and water wasted on grass. |

Sprinkler System Problem
In between the house and sprinklers not the street. Very often these are
above ground or there will be a seperate manual valve to turn off water to the zone valves for the winter and for service. Just follow the pipes and try to visualize how they would get from point to point. wrote in message ups.com... PipeDown wrote: Thanks for the advice.

Sprinkler System Problem
Each zone has a valve. You need to find them.
Each valve should have an electric solenoid and a small manual bypass knob. Turn the bypass know CCW until water flows - you should be able to hear the water flowing and the sprinklers should spray. (Don't back it out too far.) If that works, then you know your valve works and water is reaching the valve. Then turn on your timer and check for 24V at the solenoid. If 24V is reaching the solenoid you probably need to replace it. If no voltage the problem is in you wiring. Good luck. wrote in message oups.com...

Sprinkler System Problem
If you have the irrigation system already installed, and according to
your questions, contacting a professional should be a good option, I think, for the beginning. After that, you should know most of things to do with your garden. Another recommendation I should make, if you live in Texas and you have problems with water, is using a drip or micro-irrigation system. You can check the possibilities in this website: http://www.plasgotirrigation.com/products.htm I hope this information could be useful to you. ha escrito: I just moved into an old house that has a built in sprinkler system.
