How to Diagram and Install Pipes, Trenches & Timers

Last week we covered how to select and place heads, as well as how to create zones and place manifolds. This week we’ll be moving further along in the design process and even get into some installation.

Picking up where we left off, we are now going to diagram our pipe layout. First, you will choose where to cut your mainline to add a tee fitting. This tee fitting will make it possible for you to maintain water flow to your home, while still having water flowing to your sprinkler lines. The line connecting your sprinkler line and main water line will need a shut-off valve. Including the tee fitting and shut-off valve, draw a line from your mainline to your sprinkler valve box. From the valve box, draw header lines out to each zone. Look for opportunities for piping to share trench space. Once you get your header lines out to the zones, draw lateral lines. From these lateral lines you will attach a riser that a sprinkler head will connect to. Please continue reading for more detailed explanations and diagrams.

What Type of Sprinkler Pipe Should I Use?

There are two types of piping used in residential sprinkler systems: PVC and Poly pipe. Though there are other types of pipe, these the are the two that you’re likely to encounter. We’ll discuss both briefly here, plus Orbit’s contribution, Eco-Lock Sprinkler Pipe.

PVC

PVC is generally considered the stronger material used in residential irrigation, but recent developments have made us re-evaluate that view. PVC is a hard, white plastic pipe. It has very little give to it, and is thicker than poly. PVC pipe does not bend too much (or at least shouldn’t), and if it does it will snap. While PVC can withstand higher pressures, both

PVC and poly ratings far exceed that which will ever occ

ur in a residential system.

There are some drawbacks to PVC. The way PVC is made includes the use of significant amounts of chemicals that are damaging to the environment and has led to talk from environmental and green building groups about abandoning PVC. Also, the fittings used to connect PVC pipe require the use of special PVC primer and cement.

 

Poly Pipe

Poly pipe is more flexible and not as thick as PVC, and its malleable properties give it added protection in freezing areas. Because it can be bent to match the contours of trenches, it is easier to work with, requiring fewer fittings, thus reducing necessary parts and installation time.  It is also more affordable than PVC. Fittings used to connect poly pipe require the use of steel clamps.

The type of pipe you choose for your system will really be a personal preference as both have their pros and cons. PVC is a bit stronger and this should be a consideration if you’ll be doing minor digging, as it will be able to withstand a certain amount of impact more than Poly Pipe (though, neither of them will withstand very much impact).  However, when it comes to repairs, the poly is certainly easier to work with.

 Eco-Lock

You may have noticed that Orbit offers its own poly pipe, known as Eco-Lock Sprinkler Pipe. This green-colored poly pipe can be used with traditional fittings and our exclusive Eco-Lock fittings. PVC, as we mentioned before, is tougher to work with because it requires primer and cement in addition to its stiffness. Take it from a lot of professional experience, this is a hassle to work with. The primer and cement are messy and can’t be removed from clothes. Fittings need anywhere from 1-2 hours of dry time before you can run a system test. But Orbit’s locking fittings (both Eco-Lock and PVC-Lock) make installation faster and easier. They both operate by sealing fitting connections with rubber O-rings and stainless steel gripping teeth that are able to withstand over 1200 PSI. PVC-Lock and Eco-Lock fittings can swivel on the pipe to provide 360-degree directional adjustment.

 How do I Diagram Pipe Layout?

 Once your pipe has been chosen, you’re ready to diagram the layout. The water from the mainline enters your manifold contained in the valve box. Water is then released by individual valves to header lines. Header lines are usually no smaller than 1 inch and no sprinklers are attached. Rather, lateral lines branch off header lines within a single zone. Risers are attached to these lateral lines and sprinkler heads are attached to the risers. Lateral sprinkler  lines are generally ¾ inch and risers are generally ½ inch pipe. The reason we don’t attach any sprinklers to the header line is because it will decrease pressure along the way, resulting in lower pressure at the end of the line. Thus, header lines are used to keep consistent water pressure. In the example below we have header line in black and lateral lines in red.

Remember, the shortest distance is a straight line, so try to make the lateral lines branch out perpendicular to the header lines.

Diagram the runs for future reference.

One of the unique advantages to Orbit’s Online Sprinkler System Design tool is that it maps out everything, even your pipe runs. This is useful when you put in the system, but also for future reference whenever digging is required to make repairs or add more heads. It’s nice to know where everything is years later. If you don’t use the tool, we still recommend doing this. Yards change and irrigation needs should change with it.

How do I Dig Trenches for My Sprinkler System?

Congrats! You’ve made it this far and now you’re ready to start the actual installation of your new irrigation system. First step: dig the trenches. You can dig these by hand or use a trenching machine. If you’re putting in an entire system, the trenching machine is really the way to go. If you are brave, you can rent the machine and do it yourself, otherwise, you can pay a contractor to dig the trenches for you. Although it does cost money, using the trenching machine is easier than digging by hand and you can usually dig all your trenches in a matter of hours.

[stextbox id=”warning” caption=”WARNING!”]WARNING!  Whenever digging trenches in your yard it is imperative you take proper safety precautions, starting with having your local utility lines marked. If digging by hand, make sure to maintain correct posture, and take breaks as necessary. If you do it the wrong way you’ll hurt your back. Trust us on this one. If using a trencher, follow the instructions exactly. These are very powerful machines and even experienced operators have trouble with them sometimes. We also recommend wearing safety glasses and gloves.[/stextbox]

Okay, now that we’ve covered trenches, next, mark the lines. You’ve already drawn them on the diagram of your yard, so get some sprinkler flags and mark where each head will go. Next, get some spray paint used for ground marking and paint the lines on the ground. Once this is done, you’re ready to dig. If you already have grass in, you may consider putting a tarp down to throw loose dirt on as you dig your trenches. Cleanup will be much faster this way.

The trickiest part when trenching can be getting under the driveways, sidewalks, walkways, and other rocky or concrete features. The Orbit Walkway Tunnel Kit simplifies this process. This tool attaches to a hose end and uses water pressure to tunnel under these obstacles. To use the Orbit tunneling kit, dig a trench on both sides of the walkway or driveway. Attach a garden hose to the tunneling pipe. Next, turn on the faucet and work the pipe back and forth, allowing the water to spray and form a tunnel.

Now, besides digging a trench for each sprinkler line, you’ll need to dig for the main line (which municipal code may require to be a certain depth, depending on frost line conditions in your area), for the manifold boxes and a trench for the sprinkler wire leading from the manifold boxes to where your timer will be placed.

Speaking of timers…

What Control Timer Should I Select?  Where Should I Install It?

 Timer Selection

Your timer is the brain of your underground sprinkler system. It controls when and how long you irrigate your yard. Orbit timers are known for their reliability, ease of installation, programming simplicity, and their 6 year warranty.

To help you narrow down your options, select a timer that will accommodate the number of zones your sprinkler system will need. Timers can usually control 4, 6, 9, or 12 zones. If you have more zones than this it will be necessary to purchase additional timers. Orbit offers a large selection of timers to fit your needs. They are all simple to use and easy to install. Pick the timer that suits your system’s needs and personal preference.

Timer Placement

Where you put your timer is largely a matter of preference. Timers can be placed indoors or outdoors (with the use of weather resistant housings). Indoors tends to be more convenient (if an indoor space is close) and protects the timer from the elements. If your manifolds are some distance away from the manifold boxes we recommend some of our timers with remote controls that allow you to activate the different zones from a distance, which is extremely helpful when performing maintenance.

Remember to place your timer near a power source where you can access it easily. Also, consider running sprinkler wire through underground conduit to make any future expansions or repairs easier.

Next week join us again as we continue the installation. We’ll connect the system to the mainline, install necessary back-flow prevention devices, and lay the pipe.

14 Ways to Love Your Home

In honor of Valentine’s Day, we are sharing fourteen ways to love your home.

1. Set a regular cleaning schedule

There is a quote—often attributed to Benjamin Franklin—that says, “Failure to plan is planning to fail.” Don’t let this be the case with your house. Make a schedule to clean one or two rooms each day and then stick to your schedule. By doing this, you won’t have to feel overwhelmed by a day full of cleaning and you’ll feel happier and more comfortable in your home.

2. Take care of your yard

Whether you love to spend all day in the dirt or would rather be off having some other adventure, take a little time to trim the grass and keep the weeds in check. A well cared for yard, no matter the size or style, increases the value of your house and how you feel about it.

3. Transition to LED lights

While the cost may be a little more upfront, LED lights are gentler on your wallet in the long run. These lights are longer lasting and more durable, which gives you more use than a regular light bulb.

Plus, they look great in your house and in your garden. Check back often to learn more about the release of our new line of energy-efficient, LED landscape lights.

4. Plant a tree (or two, or three)

Trees are a great way to bring beauty and variety to your yard. Take care to pick the right variety for your area and need—talk with a specialist at your local nursery for more ideas. A well-placed tree can also serve as shade and protection for your yard and home and can lower energy costs.

5. Plan a date

You know that list of projects you want to get done, but never seem to have time for? Plan a date. Whether it’s a deep clean or a new paint job, your home needs a little pampering once in a while. After all, it does keep you safe and comfortable from the world outside.

6. Keep unwanted pests out of your yard and home

Whether you are dealing with deer eating your prized tomato plants, or ants invading your pantry, there are ways to protect your house. For those annoying spiders, ants, and bugs, try calling a local pest control company. If it’s bigger critters in your yard that you’re worried about, check out our Yard Enforcer. The Yard Enforcer is a motion-activated sprinkler that deters unwanted pests with sound and water. The best part? It actually works! Check out this video:

7. Increase the safety of your home

There are little things that we can do all year long to increase the safety of our homes. Whether it’s keeping the walks shoveled, or keeping our yard well lit at night (again, check back for more information on our new landscape lights), or baby proofing our cabinets and stairs, do the little things to make your home a worry-free space.

8. Give your plants the perfect amount of water

To keep your yard lush and green, give them the water they need. Our sprinkler timers are a great way to ensure that your landscape receives consistent watering, because in our crazy world, we all have a lot on our minds.

9. Try something new

Don’t be afraid to try out a new idea. The internet is full of DIY projects, for budgets big and small that may give you just the change you need. Check out our Pinterest page for some great DIY ideas for your home and garden.

10. Plant a garden

Who doesn’t love fresh produce? If the weather is nice, set aside some land and start working the earth. But don’t let snow keep you down. You can start your garden seeds indoors. What’s better than getting your hands in the dirt again? Plus, you can start enjoying the fruits of your labor earlier than if you wait to plant when the weather’s nice.

11. Give

Sometimes we let our lives get too cluttered. Instead of throwing things away, pick a number (any number) and then select that number of items to give to charity or a family in need in your area. It’s a great, and easy, way to serve your community.

12. Add some color

If you’re not ready to commit to a big color change or if you just want to update a space with this year’s color trends, try incorporating color in small ways. Buy some plants for a room, or plant some flowers in the garden—it doesn’t have to cost much to bring a lot of life to your home.

13. Take time to enjoy some peace and quiet

Whether you like to spend your time indoors or outdoors, it’s always nice to sit back and relax for a few minutes. Read a book, work in the garden, or sit on your porch and watch a rainstorm roll in. Take some time out of your busy day and do whatever it is that relaxes you. You will find that you are more centered and ready to accomplish any task.

14. Build relationships

Often, our homes are special because of the people we share them with. Don’t forget what truly makes your house a home. Take time to build those important relationships with the people you love.

 

Please share. What are some of the ways that you love your home?

How Much do Automatic Sprinkler Systems Cost? Part V

Do you need drip irrigation or garden valves in certain areas?

Drip irrigation is a very cost effective to install a system and it also happens to be a very cost effective way to water, as well. The valve, filter, and pressure regulator combination that is required for a drip zone will cost more than a control valve for a spray head or rotor zone, but the overall cost of the zone is much lower, especially if you are using emitter tubing.  Drip zones require careful planning, but are well worth the effort.

Do you need a sprinkler timer that can automatically calculate the amount of water to apply?

The sprinkler timer or “controller” can be a fairly big driver of the cost of your sprinkler system, especially if a professional contractor is installing it. The latest trend is toward “smart controllers” which automatically calculate the amount of water to apply for a given geographic location at point of time in the season. Smart controllers help reduce the amount of overwatering while helping ensure survival of your landscape in the hottest months. The downside to these controllers is that they cost more, are harder to install (they require the mounting of sensors on a roof or other unobstructed location), and more difficult to program.  Surveys of homeowners show that, while they like the concept of smart controllers, the complexity of operating them leads many homeowners to turn off the smart features and use them as a regular controller. Perhaps over time these controllers will become easier to use.

Do you need a rain sensor to automatically delay or shut off the system if it is raining?

The addition of a rain sensor to your system is pretty much a no-brainer. You can set these sensors to delay or shut off watering once they detect a certain amount of rainfall. This saves you from wasting water on rainy days and the annoyance of fines (in some communities) and public embarrassment as neighbors become more aware of water conservation.
