Tag - Irrigation System Backflow Testing

Backflow is a term used to describe a condition where water flows through a water line in the opposite direction from which it was intended to flow. Numerous conditions can cause this to occur: a broken water main near your house, firefighters using a fire hydrant in your area, or incorrectly connected pumps. These conditions can cause contaminated water to flow back into the water main in front of your house.

Is Backflow A Hazardous Situation?

Definitely. One of the more common hazards is the unprotected lawn irrigation system. If the water pressure in the water main in front of your house decreases, fertilizer and pesticides can be drawn back into the water main via the lawn irrigation system. If this happens, there is a high probability that this water will end up in your household plumbing. Anyone drinking water from your household plumbing could become very ill.

Can Backflow Be Prevented?

By installing an approved backflow prevention assembly, you can rest assured that you, your family, and your neighbors are protected from contamination from your sprinkler system.

Is A Backflow Prevention Assembly Required?

The Missouri Department of Natural Resources (DNR) requires all lawn irrigation systems to have an approved backflow prevention assembly.

Does The Backflow Prevention Assembly Have To Be Tested?

DNR requires the backflow prevention assembly to be tested annually to make sure the device is working properly.

Who Performs The Backflow Prevention Assembly Testing?

The testing must be done by individuals approved by DNR for backflow prevention assembly testing. Our certified backflow inspectors at Gabris Landscaping can test and report these results for you as a part of our basic irrigation maintenance services.

In the event that your backflow device fails inspection, we can repair or replace it as well. It is quite common for a seal or spring on a backflow prevention assembly device to bust or break. We try to keep repair kits in stock for the most common devices. Depending on model and age, a backflow prevention device is occasionally less expensive to replace than repair.

Keeping your backflow valve box free of debris can speed up repairs and keep repair costs to a minimum. Maintaining a decent size limestone gravel layer inside the box underneath the backflow can absorb moisture which prevents the individual parts in a backflow assembly from rusting together. When you can not take apart the backflow because it is rusted-stuck together, the device is considered un-repairable.

Irrigation system backflow testing is included as a part of our basic irrigation maintenance program at Gabris Landscaping. We also provide lawn sprinkler backflow testing services for clients who do not wish to be included in our annual sprinkler maintenance program.

Common Lawn Drainage Problems

Do you get a small lake in your backyard after a healthy rainfall? Poor lawn drainage is a problem that needs to be addressed and can be fixed.

Problems Resulting From Poor Lawn Drainage

The most common landscaping problem associated with poor lawn drainage is that most plants are not adapted to water clogged soils.

Turf grass can suffer from root rot, if sitting in water too long. Moss, on the other hand, never gets too much water. So poor lawn drainage tends to tip the balance in favor of moss over grass.

Most trees and shrubs are also not adapted to growing in water saturated soils. They also suffer from root rot and lack of oxygen. Some trees, such as bald cypresses and red maples, are better adapted to such conditions.

Another big annoyance that comes with bad lawn drainage is that you can’t enjoy your yard, let alone walk on it, until the water has completely dried out, which can take days. Walking on a wet lawn can cause soil compaction, which is also bad for your plants.

Sitting water close to your house’s foundations can be a big problem, since it may slowly sip into walls, possibly cause cracks, mold, and other problems.

Mosquitos may also be an issue. If the water stays on your lawn for two days or more, that is long enough for mosquito eggs to hatch.

Finding the Source of Your Lawn Drainage Problems

The first step to fixing your problem is to understand why it’s happening. Start by observing how water gets into your yard, and how it flows or sits. Then, you need to think about what you want to do with your landscaping and consider your possible options.

Keep in mind that no drainage is ever instantaneous. Rain water is never completely absorbed immediately by the soil. On lawns especially, roots can create a thick barrier that can greatly reduce soil permeability. Soil compaction may also be an issue.

Water always follows gravity and therefore ends up in the lowest point. When water falls on the ground, if it can’t penetrate the soil, it runs down to wherever gravity may pull it. And then it may get trapped if the place to which it runs happens to drain poorly.

So the two most important issues pertaining to lawn drainage are soil permeability and yard topography. Consider where the water is coming from and how it travels on your yard.

If a fair percentage of the water actually trickles down from elsewhere (your roof, your driveway, for instance) and ends up on your yard, then you need to find a way to divert the excess water, possibly using drains.

If the rain falls directly on your yard and it just sits there, then there are a few options.
You could work on the nature of your soil and the topography of your yard. You could also consider installing drains.

If the problem is not too major, you could simply get wet plants that enjoy the wet environment or create a rain garden.

French Drains and Yard Drains

French drains swallow up the water accumulating around the foundations of your house, while yard drains can drain water from anywhere on your yard.

In a setup where you have a French drain and yard drains, the yard drains may be connected to the French drain and the whole thing connected to the sewer system.

If you only have yard drains, then they may be connected to a dry well. Another possibility is to let the water escape to a stream.

In both cases, a good layer of gravel on top of the drains will help the water reach the tubes. And you need to ensure that the tubes are sloped so as to let the water flow towards the escape route, and not the other way around.

Installing drains is a big job that require finding someone like the drainage experts at Gabris Landscaping who know what they’re doing. Many drainage jobs involve digging out landscaping plants while the work is being done.

We will ensure that we leave enough roots for your plants to protect both the plants and their roots from the sun and from overheating or freezing, and that the roots won’t dry out. A good natural fertilizer helps your plants grow roots faster when we put them back in the ground.

There are many different types of yard drainage systems. Each method has its strengths and weaknesses. By combining the use of dry creeks, dry wells, French drains, standard drains, burms, and calculated plant placement, we are able to create some effective solutions to manage water flow and drainage issues. Our yard drainage systems solutions maintain the aesthetic appeal of your landscape while improving the functionality of the land.

Winterize Your Lawn

Winter is serious business here in the Midwest. Before you know it, your beautiful lawn will be covered in a blanket of ice and snow. Be sure to prepare so that your grass, shrubs, and plants spring back to life and health when the seasons turn again. Before that happens, you need to prepare and winterize your lawn so that it will be the envy of the neighborhood, when it warms back up in the spring.

Why Winterize?

You may think that your grass just sits there waiting to freeze its roots off when the temperature starts dropping. Actually, grass is smarter than you might think. Cool season grasses can feel when the temperature begins to dip, and they know that it’s time to shunt their energy away from their surface leaves and down to their roots so that they can hibernate during the winter. Come spring, your grass will need to call on those reserves of energy to do lots of growing as the weather warms back up.

A big part of winterization is giving your lawn the right dose of high quality fertilizer so that all of your plants have plenty of energy to store through the winter. You won’t be able to do a thing for your lawn during the winter months, and by spring it will be too little, too late. The time to fertilize is before winter hits.

More Winterization Tips

If you are going to make the effort to fertilize your lawn as part of your winterization efforts, you might as well do it right. Give your lawn even more support by aerating and seeding. Aerating your lawn helps introduce more oxygen into the soil, which the roots of your grass and plants will be eager to gobble up. Seeding can also address any patchy or bald spots on your lawn that a hot summer, lots of use, and pets have a tendency to create.

You’ll definitely be able to see the results of all of your efforts if you winterize the right way. When the snows melts, your grass will spring back to life, lush, green, and healthy. The more grass that grows, the less room for weeds to find their way in!

Include Your Sprinkler System as Part of Your Lawn Winterization Plan

You could perform try to perform some of these lawn winterization tips by yourself if you have the time and the energy, but there is one more important winterization activity that you should definitely hire professionals to perform. During a long, cold winter, the frost can go deep into the ground and freeze any liquid that remains in your irrigation system. Since water expands when it freezes, it can damage your lines, which will be expensive to fix.

Call the professionals at Gabris Landscaping to perform a sprinkler blowout. We use an air compressor to forcefully blow all of the remaining water out of your irrigation system as part of our winterize sprinkler system process before the winter cold sets in. A blowout requires the use of dangerous equipment, and it is not recommended that you try to do it on your own. Instead, let us handle this last part of your winterization plan. A yearly sprinkler blowout is necessary since our winters always include deep frosts.

Don’t gamble with your sprinkler system. If you want to have a beautiful yard in the spring, you need to take the steps to winterize your yard properly.

How to Water

Drip Systems —Advantage of drip systems is adding emitters and increasing the area watered as the plants grow, but most drip systems do not have enough well placed emitters.

Hoses — A perforated hose is a good device for watering, but can spray water in a random pattern.

Sprinklers — Your lawn sprinkler design can cover a large area but can be inefficient with plants, grass and trees because of wind and evaporation.

Watering Frequency

Water consumption rates vary among plant types. Plants that use a lot of water, such as willow trees, need more water than mature arid plants.

Root depth

Root depth has a huge impact on how often plants should receive water. For instance, deeper rooted plants do not need frequent watering periods, but somewhat surface deep roots may absorb the water faster and cannot hold the water for very long.

Watering Time

The amount of time needed to water your plants depends on your type of soil, your irrigation system, root depth, and weather. All of these characteristics of the plants can be seen by how quickly water is absorbed in the soil.

Weather

During the summer moths, plants tend to use 3 to 5 times as much water then they do during the winter. Watering your trees, plants and grass when summer is on the horizon is good practice once a week. If you have evergreen trees, in the winter they will keep moisture at their roots to keep from dying but generally the cold weather is normal for trees and plants to loose their leaves and even die.

Plant Type and Maturity

For new, young plants it is good to water them more than old established plants. After the new plants have been accustomed to their surroundings, and one year has passed it is good to start lessening the frequency of watering them. This allows the plant to adapt to lessened water and become tolerant.

Type of Soil Irrigation

Most of the time, you have multiple types of soil in your yard, but usually the top soil is what most people will see and use for their plants. However, if you have clay soil in your yard, this type holds water easily but if you have sandy soil, you should irrigate more often but less frequent.

Mulch

When water stays in the ground and does not evaporate, this is a good situation to be in because it doesn’t allow the plants to be in a drought or stressful situation. 3 to 4 inches of organic or rock mulch on top of a plant root area will reduce the frequency of watering because it is holding the water near the roots.

Under and Over-Watering Signs

When under-watering occurs, the soil becomes dry, the leaves will turn yellow or brown and can even fall off. Also, old leaves are wilted which shows the lack of water. When over-watering occurs there is water standing near the plant or tree, new leaves become yellow and brittle, shoots are wilted and mushrooms start to grow.
