When SHOULD you be mowing your grass??

We deal with watering times frequently here are Sprinkler Warehouse, but we are often asked questions outside of irrigation, especially dealing with grass – like, “when is the best time of day to mow the lawn?” (And lets face it, if we are doing our job and helping you to water properly, your lawn should be growing healthy and strong!)

So we did a little research and consulted with some friends who are experts in the lawn health department and came up with a few guidelines that we will share with you in a simplified form below!



Fixing dead spots, brown spots and burned grass

Brown patches and uneven plant growth can be caused by a number of factors, but in this article we are going to focus specifically on sprinkler systems as the source of the problem. Below are several common problems and some tips for fixing them.


Incorrect sprinkler head height is one of the most common problems leading to brown spots and poor growth. Heads installed at incorrect heights can also lead to damage to the sprinkler system.

Sprinkler heads that have been installed too low aren’t able to rise above the ground or turf level, or the level of the plants directly around them. This prevents the water from spraying properly, and often leads to coverage gaps and flooding around the sprinkler head. Additionally, sprinkler heads that are too low are more likely to have retraction problems and mechanism failures. This is caused by dirt entering the internals of the sprinkler head.

Heads that have been placed too high are a tripping hazard, and are a risk that could damaging lawn mowers or other landscaping equipment. The easiest way to correct this is to dig out around the head, disconnect it, and reconnect it using funny pipe or a swing joint, which can be positioned to exactly the right height.

Another common cause of incorrect sprinkler head height is the natural growth of surrounding plants. A sprinkler head that was installed correctly near a shrub may need to be adjusted as the plant grows. Sprinkler heads watering ground cover plants will also need adjustment.

Over time, ground levels can raise or lower (soil is washed away with rain and flooding, and built up with decomposing leaf matter, grass clippings, etc.), which can cause a sprinkler head to be too high or too low. Either way, the best solution is to dig it out, remove it, and reconnect it using a swing joint or funny pipe. All sprinkler systems should be checked periodically to verify that the heads are still at the correct level.

Clogged Nozzles:

Clogged sprinkler nozzles are caused by dirt or debris working its way into the sprinkler head. This can prevent the sprinkler head from spraying properly, causing gaps in the spray pattern, which will lead to brown patches. The first step in diagnosing brown spot is to observe the sprinkler while it is running. You’ll be able to see if overgrown plants are blocking the sprinkler, the head is broken, or the spray pattern is being internally disrupted.

Note: Don’t try to remove a nozzle by prying at it with a screwdriver. Both rotor and spray nozzles are easy to remove, but must be removed carefully to avoid damage.

Wrong spacing of heads

Even if sprinklers appear to be spraying evenly over an area, there may be gaps in the coverage. When planning and installing sprinklers, it is important to lay out the heads with “head to head” coverage. This means that the spray from one sprinkler head should reach the next closest sprinkler heads, and vice versa. Head to head coverage creates optimum watering overlap, and help compensate for spray pattern imperfections.

Uneven growth or brown patches in your lawn may be an indication of damaged or clogged heads, or improper installation or placement. It is important to check all these possibilities, and repair or correct any problem areas to maintain a healthy lawn. Often, poor coverage will not manifest itself until severe hot, dry weather conditions prevent your lawn from receiving supplemental water through rainfall. New plantings can also reveal problem areas, as they have not yet developed mature root systems. additional watering times or hand watering can help, but the best solution is to adjust your sprinkler system properly and clean or repair any damaged or clogged heads. A well-maintained, properly installed and adjusted sprinkler system will keep your landscape well-watered, beautiful, and healthy.

Irrigation retailer Sprinkler Warehouse releases new perfume system for your yard!

It is not uncommon now-a-days for a person to apply perfume or cologne before going out on a date or to work. You buy fragrance clips and hangers for your car. You even buy candles or outlet plug-ins for your home! So it makes sense that you would want your yard to smell just as good as the other parts of your life!

Online sprinkler retailer megalith, announced today the release of a new fragrance delivery medium for your yard using your yards existing sprinklers system. The kit can be used with underground sprinklers or hose end sprinklers alike. Using a patented, proprietary injection system, the fragrance is evenly applied across the yard and is controlled using an “on-demand” smart phone app. The app lets the homeowner control how much fragrance is dispensed, and for how long. You can even switch between different scents (with optional kit, sold separately).

Perhaps the  most exciting news about the scent-system is that it can use your own favorite perfumes and colognes! However, if the thought of spraying your $300 bottle of Creed or Le Labo onto your yard is more than you had in mind, Sprinkler Warehouse offers a range of less expensive scents that can be purchased directly including; freshly cut grass, Sun-dried clothes, campfire, tropical island seabreeze, or even new car scent!

This $3 part can save you thousands after a cold winter night.

Tired of blowing out your sprinkler system each year in preparation for cold — you wait and wait for the day when the temps dip below freezing to validate the hard work you did to purge every last drop of H2O from the myriad of pipes and elbows and rotor heads. If you live in a part of the country where freezing pipes are not a primary concern than there is one very simple device you can install in just minutes that will always be watching over your pipes and protecting them from damage year round…

What is the name of this oh-so-valuable part? Its called a lateral drain!

Lateral Drains (sometimes referred to as freeze drains)are a very simple device that do not require any electricity, maintenance or attention on your part to work. simply install them and forget about them! Each drain works using a one way valve that stays open  when there is not pressure in the system, and it closes itself whenever there is water in the pipes. The primary benefit of the automatic drain is that it will allow the water that remains in your pipes after shutting off the sprinklers to have an easy path out of the pipe.


Broken pipes occur when the water inside your pipes reaches a freezing temperature and expands as it turns to ice. Without anywhere to go when it expands the ice will force it’s way out of the pipe either by splitting the pipe or breaking a valve or rotor or worst of all a backflow preventer!

You can purchase automatic drains in a variety of styles, but each uses the same primary design to allow the left over water to pass through them. Some drains use a spring to control flow while others use a loose metal ball inside the device that moves out of the way to let water by.

How to repair a backflow by installing a new “Bonnet & Poppet”

Cold weather is finally here and regardless of where you live, there are certain things you need to know about your sprinkler system that will help you to avoid unwanted repairs or costly repair service calls. If you have a sprinkler system chances are that you also have a backflow preventer. A majority of backflow preventers are designed with a fail-safe in mind to prevent irreparable damage. The following guide will outlines the steps necessary to repair your own backflow preventer if freezing temperatures have damaged it.


1. Shut off the water supply to the backflow preventer.

At Sprinkler Warehouse, the 4th of July is one of our favorite holidays! Summer is in full swing, grass is green, trees are filled with leaves and flowers are blooming all around us. Its a great time of year for having a picnic, or getting out of the house for a game of soccer, baseball, volleyball, frisbee, golf or any other activity that you can enjoy with friends and family together. It makes us proud to know that the green, lush carpet of grass that everyone enjoys all day long, from the parades in the morning, the afternoon picnics and the evening fireworks, is green and lush as a result of excellent watering! So this forth of July holiday, when you are out and enjoying the grass somewhere in your city, lawn or park, take a minute to look around and notice the sprinklers those sprinklers that make that grass so green and nice to enjoy!


The picture above is of the sprinkler warehouse team members who dressed up (even the slightest) in celebration of the holiday.  There are 5 shirts in 5 different colors that correspond with a schedule. Blue Shirts on Monday, Grass green shirts on Tuesday, Navy Blue on Wednesday, Forrest Green on Thursday and Royal Blue on Friday. Since the 4th of July falls on a Friday this year, we will have the day off, so to celebrate the freedom holiday we wore our Friday shirts on Thursday in place of the usual forest green colored shirts. We were also invited to accessorize our outfits with any red white or blue we had. The people in this photo,  are those employees (including yours truly) whom went the extra mile to add a touch or two of patriotism to their outfit.

So this 4th of July weekend we hope that you have a fun, safe and exciting time with friends and family. Please be responsible with fireworks, alcohol and on the roadways.



When To Water & For How Long?

When should I water my lawn and for how long?

Regardless of whether you live in the country or the city, the best time to water your lawn is in the early morning. This is the time of day when your lawn will absorb the most H2O and you will lose the lease H2O to evaporation. However, one bonus to watering in the early morning for city dwellers is that the water pressure will be at it’s peak before the population of you city gets up and starts using up all that water pressure for showers and baths! For rural folks, whose water comes from a well or direct from a lake, or pond or other source through an onsite pump.

Avoid watering during the day time, especially when the sun is at it’s brightest. Only a fraction of that precious water will actually make it to the grass.

How much should I water my lawn?

The amount you must water your lawn is largely impacted by the amount of rainfall you get where you live. This will be driven by the weather and a phenomenon called evapotranspiration (i.e. “ET”.) ET is the combined effect of water used by the plant and that which is lost to evaporation. ET is expressed in inches (or mm) of water per week. So based on the amount of water your grass takes in for nutrition and the amount of water that the environment takes out of the soil, you will have a new amount of water that has been debited due to ET and must subsequently be replaced.  Often times a local university will have accurate ET rates for your area of the country. You may also be able to find these rates published regularly in the newspaper or on a website.

How deep into the soil should water penetrate?

Soil-depthGenerally speaking, water should be able to penetrate down 6-inches into the “root zone” of the lawn. Ideally it is time to water again when that water level is at about 3-inches. You can check this in a variety of ways, by using different tools such as a shovel, a soil sample puller, or a digital sensor.

How much is too much (or too little?)

Most people are surprised to discover that there is more damage done, by overwatering a lawn than by under-watering it. This is due largely in part to the plant structures inability to extract the water left in the soil once so much water has washed through it. Without the water to provide it nourishment the grass becomes susceptible to insect problems, physical damage and disease.

What happens to grass during a drought?

ng655_01_front TurfSpyGuideIf your lawn can’t get enough water it will first go into a dormant stage, often marked by a bluish color. If the drought continues until the soil water is fully used, death will result for most cool-season grasses. Bermudas and other warm-season grasses will probably recover, however, the lawn’s quality will not.
