• How much water does my system use?

    To make the math easy use the following- each rotary head uses 3 gallons per minute and each spray head uses 1 gallon per minute. Multiply the number of heads times the appropriate gallons. Then multiply that number by 60 (minutes per week) and 30 (weeks per year of watering). That will give you annual usage. To break it down a little more by quarter- Q1-0; Q2-30%; Q3-60%; Q4-10%.

  • When and how long should I water?

    We recommend asking your lawn care professional for watering instructions. They are responsible for making sure all of the fertilizers and weed controls are working. Beyond that, we recommend that the system operate between 2am and 6am on even or odd days- whichever corresponds to your house number in order to abide by watering restrictions.

  • Can I adjust the heads myself or reprogram my controller?

    Absolutely! Click here for video tutorials from Hunter and Rain Bird:

  • Can I aerate my lawn?

    Yes! Make sure you mark out all of your sprinkler heads ahead of time and avoid those areas with any equipment.

  • How long will the installation take?

    The average size home sprinkler system takes 1 to 2 days to install. A large estate home can take from 3 days to 1 week. A large commercial system can take months, or even years to complete.

  • Will I have to shut off the system when it rains?

    No, by law (The Water Conservation Act ) all new sprinkler systems come with an automatic rain sensor which will turn the system off when significant rainfall occurs. It will automatically reset itself when the rain ends so even if you are on vacation your system knows what to do.

  • How soon can I have my new system installed?

    Usually our schedule will allow us to install your system 10-14 days after you give us the ok. By law, permits are required and all properties have to be marked out for underground utilities which usually take 7-10 days.

  • Are permits required?

    Yes, each town has specific permits which are required. We will file these permits on your behalf as part of our agreement with you. You will only need to pay the specific fees required by the township and then arrange for the final inspection.

  • How long is my new system guaranteed for?

    We install all major manufacturers irrigation materials and those materials are warrantied for 2-5 years depending on the product. In addition, our company guarantees everything we do (including labor & adjustments) 100% for 1 year.

  • Will my new system need ongoing service in the future?

    Your new system will need to be winterized every autumn which we will do with a large air compressor. In the spring, the system will need to be turned on again and programmed to run. You can have us do this or you can do it yourself. On occasion the system may need service. Garden Irrigation prides itself in our dependable service technicians and our great customer relations. If you need us we are only a phone call away.

  • What is required service after installation?

    The only necessary service is the winterization of your lawn sprinkler each fall. It is important to remove all standing water from the system to prevent freeze damage. We also offer the option of a spring start-up and mid-summer check up.

  • What kind of products do you use?

    Garden Irrigation is using the best products in the industry like: Hunter, Rain Bird, Toro, Irritrol, and Netafim. If you have a product you specifically want, we can get it just for you.

  • What is drip irrigation and what will it do for my landscaping?

    Drip irrigation is a method where small amounts of water are placed on the root ball of plants, using the water more efficiently. This is done with a network of small tubes that provide water to many plants at once. It is generally considered to be better for most planting beds than typical watering, and it wastes almost no water.

  • How often should the sprinkler system be run?

    Each lawn has different sun and soil conditions that require varying amounts of water. It is better to water deep and infrequently rather than lightly every day. Other factors include the type of sprinklers used, direct sun, shade, soil conditions, slope, and temperature. Generally its best to water as much at once as possible without creating run-off, then waiting as long as possible before watering again.

  • New Installation Guide

    Congratulations on the completion of your new irrigation system! For the first 30 days, your system should be set to water every day for a minimum of 20-45 minutes per zone of rotating heads based on the weather. Spot seeding will help fill in disturbed areas faster. Zones with mist/spray heads (that do not rotate) need less time- only 5-15 minutes. After this period, a recommended schedule is every other day (odd or even corresponding to your house number) for same duration.
    As the season goes on, you may notice that different parts of your property need more or less watering time based on sun exposure and slope. Remember- each zone can be changed individually. Please adjust these zones on the timer accordingly.
    As the temperature rises and there is less rain, your lawn will need more water. You will need to change the timer settings for more time and frequency, and less time and frequency as we approach the fall.
    The best time to water is in the early morning. This reduces fungus growth and rapid evaporation.
    Every year, you must winterize the irrigation system. Your quoted price is on your contract. This should be done in October, before the first frost. We will e-mail you a reminder.
