Frequently Asked Questions

Does Vanderwist guarantee their work?
Warranty: Vanderwist of Cincinnati, Inc. and it’s divisions warrants all installations to be free from defects in material and workmanship for a period of one year from activation or substantial completion of system. Gear driven heads, valves, transformers and controllers are warranted for 2 years for material only.

Is yearly maintenance covered under the warranty?
Typical irrigation maintenance, i.e., winterization, spring activation and site inspections are not covered under a warranty. Typical lighting maintenance, i.e., resetting transformers, resetting timers, cleaning lenses, and changing of bulbs are also not covered under warranty.

Do I need to be home during the installation process?
We feel its important for you to be home at least during the first phase of the installation so we can cover such items as controller location, valve placement, special concerns and unmarked lines location which might be damaged during the installation such as dog fences, drain lines or low voltage lighting. Also it is very important to review property lines which should be clearly marked by property owner and reviewed with a Vanderwist representative.

Will you tear up my lawn or ruin my shrubs during the installation process?
Vanderwist uses a vibratory plow for most of its installation instead of a trencher. A plow "pulls" the pipe and wire under the ground and is less intrusive than the trenching method. Vanderwist will make all possible efforts to save existing turf and landscape. If irrigation and/or lighting is installed in beds, we make every attempt not to disturb plant material. Our customers are often amazed at the care we take cleaning up at the end of the project.

Why do I need a backflow and are there any fees associated with the unit?
County water departments and plumbing codes require the use of backflow devices to protect the potable water supply in many of our service areas. Some backflow devices are designed to dump (relieve water) to equalize pressure. Reduce Pressure backflows can likewise; stick open due to debris induced by the city water supply. Debris may be found in the city water supply due to activity on the water main such as a break, fire, of regular hydrant flushing. When backflows are required, the initial permit fees and testing are included in the installation price. Future testing and fees are the customer's responsibility and typically run anywhere from $80 - $125 each year.

How much maintenance is involved with my lighting system?
Although maintaining a lighting system is relatively easy and is not time consuming, we suggest a yearly site inspection to clean lenses, remove debris from fixtures, go over adjustments and if necessary to change out bulbs. Our service department can arrange this service for you. We also have bulbs available to you at our division locations or we can UPS the product directly to your home or office. Please Note: Periodically, it is wise to inspect your lighting and to make sure leaves, debris and mulch are not covering the lamp, which may increase the risk of fire.

How can I arrange for maintenance on my system?
Warranty, as well as service issues can be scheduled through our service department. Regular office hours are from 7:30 a.m. to 4:30 p.m., Monday through Friday. To avoid the spring and winter rush, advance scheduling is available and recommended when scheduling your winterization and spring activation maintenance calls. If you wish to order parts either for your lighting or irrigation system, we can UPS the order to you or have them available for you at any of our division locations.

When building a home or office, when is the best time to install the irrigation/sprinkler system?
We feel it is best to install the irrigation system after all driveways, walkways, decks, patios, and landscape beds are installed. A clean site and final grade should also be completed before we begin. We should be one of the last trades on your site just before you seed or sod. Please remember to have your contractor install sleeves under the walkways and driveways. Please discuss any other concerns with a Vanderwist representative.

Why are there two types of heads in my lawn?
Gear driven heads are for larger turf areas and spray heads are for smaller turf areas. Gear driven heads are designed to water up to 40 feet as spray heads can cover up to 15 feet.

Where do I shut off my system if I have a problem?
Most Vanderwist installed systems have two shut off locations typically one inside the house as well as outside of the house.

I turned off my controller but the water will not shut off?
Turning the controller off will not stop the water flowing inside your main line. If a valve is stuck open, the only way to turn the system off is to turn the water supply off to the irrigation system.

Why are my lawn heads not covering my flowerbeds?
Irrigation systems are designed to water the beds and lawn areas separately so you do not over/under water delicate plant material.

How do I maintain my irrigation/sprinkler system?
Irrigation system should be activated yearly checking the pressure on the main line, head and valve adjustments, position of heads, copper work and overall performance. We also suggest winterizing your system each year before the temperatures go below freezing.

Can a rain sensor be installed on my system? What are the benefits?
Yes, the Hunter Mini-Clik®, Rain-Clik™ and Wireless Rain-Clik™ are compatible with all brands of irrigation controllers and can be installed by Vanderwist. Currently the states of Ohio and Indiana do not require rain sensors on irrigation systems but it is a good idea to have one on your system. They help to save water by interrupting any automatic cycles scheduled after enough accumulation of rain has occurred. This not only saves money, but can help to make sure that plants are not over watered and can keep you from the embarrassment of watering while it is raining. Even with the use of a rain sensor, the best monitor for an efficient watering system is an educated user.
