Yard Service and Irrigation Repair Specialists

Irrigation Installation

Your home's irrigation system is the backbone of your landscape.  When designed and functioning properly, it will provide you with a healthy, beautiful landscape.  When designed and functioning poorly, it can cost you money in many ways.  From a higher water bill to plant replacement to repair bills to HOA fines.  A poorly designed and installed system can cost you more money in the long run than having it done right from the start.

At On Par Landscaping we don't just get the system in the ground for you. We use superior grade materials and sound design principles to give you a professional grade system that functions properly and lasts for years and we guarantee all parts and labor for two years.

All of our components are installed professionally to give a clean look!  We mount all of our controllers securely to the home and hard wire them to the breaker box for a clean and tidy look!  We install our valve boxes near flush and level with just enough rise to keep the surrounding rock out!

Here's a list of what we put into our irrigation systems.  When soliciting bids, ask potential installers if they do the same.

Schedule 40 vs Class 200 PVC Pipe

Most installers will use Class 200 pipe, commonly refered to as "class" pipe.  This is an inferior pipe that is thin walled and easy to puncture.  It typically costs 10 cents less per foot than higher grade pipe which is why it is the pipe of choice for most installers.  We only use Schedule 40 pipe which has a thicker wall and is a far superior product.

The Schedule 40 pipe on the left is easily twice as thick as the Class 200 pipe on the right.

Cut Of Risers vs Swing Joints

Most installers will use cut off risers to attatch the sprinkler body to the pipe.  This is a rigid connection that doesn't allow the head to give at all in the soil and is easily cracked when the head is run over or struck at a side angle.  We use swing joints that, in addition to allowing the head to give, allow us to set the head flush at the soil level.


As you can see, the cut off riser on the left is rigid and offers no flexibility while the swing joint on the right offers plenty of give and flexibility.

We Only Install 4 Inch Pop Up Heads

The cost difference between a 2 inch and a 4 inch pop up sprinkler head is negligible, but many installers will use a 2 inch model simply because they don't dig a deep enough trench to get a 4 inch head below grade.  Anything less than a 4 inch pop up is unacceptable.  The spray head needs to get up above the grass canopy to provide proper coverage without the spray being blocked.  It's not uncommon to keep a lawn cut at 2 inches and winter lawns should not be cut below 2 inches.  If your sprinkler head is only popping up 2 inches, what happens when the grass grows up above 2 inches?


The 4 inch pop up on the left easily clears the grass canopy while it's obvious the 2 inch model on the right would get very little clearance at all.

This is a classic example of what happens when the grass blocks the spray of a sprinkler.The heads are located along the perimeter.  As you can see, the grass close to the heads is lush and geen from over watering by knocking down the spray while the grass in the middle is being deprived of water.

This is an actual photo from a competitor's ad.  You can see the pipe is no more than four inches in the ground and the 2 inch spray head is attached to the pipe with a cut off riser.  Obviously the trenches were hand dug and the installer was forced to use inferior methods to get the sprinkler heads below grade.  Pipe this close to the surface also runs the risk of being punctured by an aerifier.  The ad claimed over 10 years experience.  We have over 15 years experienc of doing things the right way! 

We Use Advanced Nozzles With Matching Precipitation Rates

Spray nozzle technolgy has come a long way.  In the past, only fixed pattern nozzles were available ranging from quarter circle to full circle.  Most lawns in the valley are irregular shaped and don't lend themselves well to set spray patterns based on a square layout. 

The first major advancement was adjustable arc nozzles which allowed for spray patterns that covered the curves usually found in valley lawns.  While a major improvement, this did not adress the problem of even coverage throught its radius and consistent output regardless of spray pattern.  In other words, a normal spray nozzle puts out more closer to the spray head and a nozzle set at 90 degrees will put out more water over the same time period as a nozzles set at 360 degrees.

The next step in the evolution of spray nozzles is Hunter's MP Rotators which put out even water thoughout its coverage and its precipitation rate is consistant regardless of radius.  This is the only spray nozzle we use.  This nozzle makes better, more efficient use of your water which saves you money!

We Install Filters And Pressure Regulators On all Drip Lines

Some installers will forgo this and simply hook the dripline up to a valve.  Drip systems and their components are designed to be low pressure systems.  Allowing full pressure to the system results in premature drip line failure and emitters to overwater.

A proper drip zone vale should have and inline filter and pressure regulator typically set to 35 PSI

We Only Tap In To A 3/4" Or Greater Water Source

When adding to an existing system, our first choice is to extend off of that.  In some cases it's necessary to tap another source.  Some installers will chose to come off of a 1/2" line for a hose spigot.  This line is too small to allow adequate flow for the irrigation system.


This is a backflow prevention valve tapped on to the main line coming into the house.  This is the ideal source for your irrigation water as pressure and flow will be the greatest.  It's important to note that a backflow valve is required by law.  This device prevents any water that has entered the irrigation system from being pulled back into the home's water system.  This valve should be installed with copper pipe on both sides of the valve going into the ground.

This is another photo from the same competitor's ad.  As you can see they have tapped on to a 1/2" hose spigot line.  Not only will there be flow issues but the small 1/2" line has to carry the weight of the backflow valve.  They have also chosen to come off of the valve with PVC.  When left above ground, PVC quickly breaks down from UV damage and becomes brittle leaving it prone to pressure blow outs.  This is a classic example of how not to do it.  Again, this competitor boasted 10 years of experience.


Some installers will instal anti siphon valves, as shown on the left, instead of using a backflow valve on the main.  While legal, these valves are unsightly and the lines are very susceptible to breakage.  We always use brass backflow valves which allows us to use inline valves that can be installed below grade in a valve box as the photo on the right shows.

We Only Use Commercial Grade Controllers From Hunter

The controller is the nerve center of your system.  Our clocks are user friendly and offer a wide range on programming features to meet the diverse needs of any landscape.  Don't trust your investment in an irrigation system to a do it yourself model from the local big box store.

The Hunter X-Core controller is economical, solid and reliable.  This controller can handle the needs of most residential applications.

This is a photo from another competitor's ad stating "their customers appreciate the quality work and low rates".  We certainly hope this customer recieved an unbelievable rate considering everything that is wrong in this photo!  The controller and valves are low end products from the local big box home improvement store.  There is no need for above ground anti-siphon valves when a brass anti-siphon device is already being used.  Having the valves above ground as well as using PVC above ground exposes the plastic components to the sun which causes premature failure as well as exposing them to possible freezing in the winter which the plastic components are highly susceptible to breaking in these conditions!  The controller has exposed wires coming out of the bottom and is plugged in to an outdoor outlet.

As you can see from the picture above this one, we always use conduit going into our controllers and we always hard wire our professional grade controllers!  We leave nothing exposed to the elements for a clean, professional looking instal!

Don't trust an inferior grade controller to handle your landscape investment!

Installation Prices

Our price guide applies to any residential subdivision home with a lot size of 25,000 square feet or less.  If you have a larger project, please call for a free onsite estimate and consultation.  We use high efficiency Hunter MP Rotator heads for all turf applications.  A typical turf zone can support up to 8 heads and cover up to 1,200 square feet. 

Typically a single drip zone is sufficent for either a front or back yard.  All drip zones include running emitters to all existing plants as well as any future plant locations as desired.  We match emitter output to specific plant type and add multiple emitters to larger plants and trees.

Multiple drip zones may be neccessary in case of extreme plant diversification.  If you wish to have pots and containers set up with a drip system we highly recommend a dedicated zone as these require much less water as plants in the ground.

Bubbler and spray zones are also available for annual beds!
