There are basically two ways of determining your maximum flow rate in Gallons per Minute (GPM).

If your pressure is significantly lower, you can consider buying a pressure booster pump – you’ll probably save more than what the pump costs due to the way adequate pressure simplifies the overall sprinkler system design.

You may want to install a pressure regulator if your water pressure is higher than this, if only to save the inlet valves on your domestic appliances from wear and tear. Also make sure that all the taps in the house are closed and the dishwasher isn’t running: pressure drops as flow rate increases.Īny reading between 50 and 60 psi should work well with a sprinkler system. Remember to check this at ground-floor level, again because water pressure varies with height. However, especially if you live in a hilly area, this may be fairly inaccurate – a rise of only 30 feet changes the pressure by almost 15 psi – so it’s better to use a cheap pressure gauge to get an exact reading. One way to determine your water pressure is to simply phone up the utility company and ask for your neighborhood’s “static” pressure. This level is reduced in a number of ways before it gets to your house and varies considerably between different properties, so it’s important to get an idea of what you have to work with. The pressure in those big concrete pipes used for water distribution is typically around 10 bar (150 psi), which is enough to dig an impressive crater when one bursts. If you’re unsure of either, it might actually be cheaper to pay for professional, hassle-free installation.Īs we’ll get to in a little while, the type of pipe you use and the distance between the supply and the sprinkler head also play a major role. On a closely-related note, you’ll have to be honest about your DIY skills and the amount of time you’re willing to put into this project. When it comes to sprinkler systems, you can generally expect to pay between $0.25 and $1 for every square foot covered, and trying to save money by cutting corners is rarely a good idea. You may have to settle for a smaller installation than you originally had in mind and plan for it to accommodate future upgrades or expansions. We might as well take this opportunity to point out that the last part – figuring out what everything will cost – is often where expectation meets reality, painfully. Some of these preliminaries may seem tedious, but they’re definitely worth knowing about. We’ll be covering each of these aspects in detail down below, hopefully answering any questions you have along the way. Mistakes and oversights are much less likely when you have a framework like this to guide you through the process.

It works equally well for planning a totally new system or tweaking an existing one.

Sometimes, these are used to confuse customers: How Landscape Architects Approach Irrigation (and How You Can, Too)Įvery profession has its conventions and jargon. Think of it this way: plants basically need dirt, sunlight, and water – only one of these is really under your control. Crucially, aside from layout and plant selection, designing an efficient irrigation system is a large part of this. Planning a garden is therefore all about finding the best possible compromise between your horticultural dreams and your resources. All plants won’t grow well or even survive in every climate zone your soil type may not be adequate for what you have in mind, and the time and funds needed to realize your vision may just not be available right now.
