Sprinkler Irrigation 123 Tutorial

As the Canadian Spring and Summer months approach each year the most common enquiry we receive are from home owners wanting to install a Sprinkler Irrigation System for their home or cottage. With contractors charging through the roof installation fees and offering systems that are often times too complex to understand, home owners are turning to DIY installations but don't know where to start.

We have good news! IT'S NOT THAT HARD TO DO!

This tutorial is intended for home owners who want a system that works, is inexpensive, and relatively simple to install. Don't kid yourself, you're going to have to do some leg work but in general it will be less painful than you think. We will look at systems for small to medium sized yards and assume the hook up will be from a standard outdoor faucet (yes you can install from a faucet).

Notes Before You Begin: We have based this tutorial on assumptions which are common to many sprinkler designs we have completed in the past to provide a simple approach to a successful design and installation.

1. MP Rotators - We recommend all home owners with small and medium sized lawns (and large ones) to design systems using MP Rotators from Hunter. These nozzle/spray body combinations provide the most efficient watering system available for lawn applications and also make designing your sprinkler system a simple process. For more information and videos on MP Rotators please visit the Hunter Industries Site Click Here.

2. We will assume a flow rate of 280 gph and a minimum of 60 PSI which is the flow rate and pressure of a typical residential water supply. However, before you begin the design process you should take the time to note the flow rate and pressure available from your hose faucet. 

Calculating The Flow Rate:  Take a pale and measure the time to fill it when the hose is on full. 

For example: A 5 Gallon Pale takes 45 seconds to fill.  There are 3600 seconds in a minute.  Your calculation is 3600 / 45 (to calculate how many pales you can fill in an hour) x 5 gallons (size of your pale).  3600/45 = 80 pales, 80 x 5 = 400 gph.  

The 3 Step Process To Designing a Sprinkler System

1. Plan Your Layout

2. Calculate Your Zones

3. Choose Your Components

We will now look at each individual step in detail using a sample installation.
