• All hazards, densities and areas of application for end or centre fed, looped or gridded sprinkler systems or any combination
• Room Design or Area / Density type calculations to set out the operating sprinklers
• All types of heads - upright / pendent, ESFR, quick response, large-drop etc
• All pipe, fitting and valve types stored in user editable database(s)
• Can be used in two ways, either by Computer Aided Design or created directly
• You can simply draw an isometric-like drawing using LINEs in CAD (LibreCAD is free), then add some data relating to each pipe with TEXT entities in the centres
• Alternatively, you can use options like add, break, copy, delete, edit and move to sketch out the hydraulically remotest area within FREEHCP - very quick and easy to follow / revise
• Every time you make a change, the updated calculations are instantly displayed with multiple undo / redo
• Gives a clear Water Supply Graph and Results Presentation on screen, PDF files or to print out
• Also spray, deluge, drencher, birdcage, ring-main, special-risk type water based fire protection systems to the NFPA 15 standard, with or without velocity pressure
• Produces a file specifically for AHJs so they can see all of drawing, graph and results themselves
• If you need to verify that I have used the correct equations and procedures, just ask for the source code of FREEHCP
• Very simple to use but comprehensive in scope / ability
• It will only take you a few minutes to download my latest program and run through the four examples to establish that FREEHCP will be of immediate use on your projects and to directly compare it with your current program.

FREE program #1 of 22 : FIRSTHCP

FIRSTHCP is simple 'point and click' drawing program for first-time users to the NFPA 13 / 15 Rules and dating from March 2017.

DOWNLOAD this program now or READ MORE about it ...

FREE program #2 of 22 : CAD2HCP

CAD2HCP will permit you to prepare your sprinkler layout drawing with any 2D CAD program (the excellent free LIBRECAD one is shown here), following a few, simple guidelines to add some text alongside the pipe sizes on the LINE / CIRCLE entities :-

Choose 'Open' in CAD2HCP to select the file name to see this automatically generated 3D isometric using these items of text :-

Just click on the heads within the required branch lines to immediately do all the full hydraulic calculations with the flow rates shown and the most remotest head in green :-

One more click will show part of the RESULTS (use the 'arrow' keys to see the rest) :-

and one more click will PRINT to PDF or inkjet/laser printer if needed, or SAVE TO JPG, ZERO HEADS (to start a new design area) with other 3D views of your system and helpful labels (such as pipe pressures shown here) 'zoomed in' :-

I think you will find CAD2HCP is a viable, zero-cost alternative to your current task of abstracting and duplicating a lot of information and data from the sprinkler layout drawing to / from a separate hydraulics program, for the same project. With my latest program, the 2D CAD drawing is the hydraulics data file to the latest NFPA / FM Rules in metric units. Just by adding a few more notes next to the pipe size (that you always show anyway), you don't need to buy any Building Information Management (BIM / REVIT) programs or continue with your existing hydraulic calculations software. If you wish to follow the EN12845 (and similar) Rules, please continue downwards to CAD2ENRULES.

FREE program #3 of 22 : CAD2ENRULES

You just draw out the sprinkler heads and pipes following some simple guidelines in your existing CAD program and add sizes / notes (mainly on vertical pipes) and you have finished - both the layout drawing AND as many hydraulic calculation areas as you want a few minutes later with this program.

The following screen shots show how you run CAD2ENRULES with your 2D CAD layout drawing all done in LibreCAD or similar (here zoomed in to the top left hand corner) :-

Choose 'Open' in the program (under Windows 7) to see the 3D isometric full size :-

Just draw a 'box' around heads in a plan view or click on the heads at the end of the required ranges in an isometric view to immediately do all the full hydraulic calculations with the flow rates shown, with the most remotest 4 heads in green :-

One more click will show part of the RESULTS (use the 'arrow' keys to see the rest) :-

and one more click will PRINT to PDF or inkjet/laser printer if needed, or you can get other views of your system with helpful text information. Here I have selected to view the pipe pressures and right clicked to zoom in - what could be easier?

All the information about the project data, layers, sizes, design parameters, pipe sizes / types / bores and fitting types / equivalent lengths is stored in BSEN12845.TXT - but you can add to, change or copy it as many times as needed for your own country / company / specific projects / CEA / DBI / CP52 / AS2118 etc Sprinkler Rules and can even translate the text into your own language as shown below :-

No longer do you have to waste a lot of time in entering most (if not all!) the pipework / sprinkler heads that you have already drawn on the 2D CAD sprinkler layout plan into a separate hydraulics calculations program. Just by marking on a few extra items of text next to the size in mm against the pipes in CAD, I can produce a 3D isometric instantly and automatically so that any design area can be selected, the complicated 'sums' done immediately and the familiar results presentation shown on screen / printed out. Try it out for yourself for FREE today and compare it to your existing design office procedures / workload - there are 6 demonstration examples to aid this evaluation. If you wish to follow the NFPA / FM Global Sprinkler Rules, please go back up the screen to CAD2HCP.

FREE program #4 of 22 : ISO2HCP

You prepare your isometric layout in your chosen CAD program as normal drawing the pipes as lines and the notes about the project data / design parameters / pipe sizes x lengths as text entities :-

Run ISO2HCP and select DEMO1 from the 'File options' menu to see the project data, calculations summary and then the same drawing with all the flow, pressure, velocity etc hydraulics data displayed by moving your mouse over the pipe of interest :-

Thats all! No need to node up the pipes, type in all the size, length, direction etc information to a separate full hydraulics program - this has all be done directly from your isometric - what could be easier?

Calculation of hydraulically designed sprinkler (room design and area/density methods) and spray systems to the NFPA 13/15 and FM Global Rules in metric units. Node references are only required at tees / crosses (not at each end of all pipes) and you give the size, length, direction and slope of the pipes to the operating heads / nozzles so a 3D picture is produced as a DXF file. There is just one way and place to add, break, copy, delete, edit, move, locate or view pipes - no confusing options to learn or superfluous videos / manuals needed to find out what does what! You may have a background CAD drawing so can 'draw' the pipes on the building / rooms / services plan rather than a blank screen. See the CAD2HCP program above if you prefer to do the CAD drawing first.

Click here for tutorial [24th January 2013 - about 9kb - just 'Save' it to somewhere on your hard disk]. I have redone this as as .RTF file so users with HD screens can just reduce the width of FREESHP and have WORDPAD or similar running alongside, making it easier to step through the various options and see the program in operation.

SUMMARY OF ALL ABOVE :-

Yes, all of my cost-effective 'Windows' programs will not cost you anything :-

Sprinkler Software Free Install

• All are fully up-to-date and comply with the latest, most common sprinkler rules - NFPA, FM Global and derivatives of EN12845
• Metric (S.I.) units applicable worldwide - only FREEHCP applicable in America
• Printout formats and screen displays acceptable to the respective Fire Authorities, Reviewing Bodies, Insurance Company inspectors in your country, subject, of course, to individual job checking
• None, however, have ever been 'approved' by any of these organisations as they would never do so for any program that they did not directly control and only commercial firms and dedicated individuals will ever produce such specialised software
• Some suppliers say that their programs follow the NFPA 13 / 15 / 750 Rules but the printout format is nothing like that given in the NFPA documents so unlikely to be acceptable
• All calculations are performed in accordance with established sprinkler rules and so give EXACTLY the same answers as the few ~20 year old programs many of you might still use or have purchased
• There are NO other free fire sprinkler hydraulic calculation programs elsewhere on the Internet, so no point in searching for alternatives as you have found them all here
• Other sites may say their programs are free, but that is ONLY for download and 15 / 30 day trials - you have to PAY to actually use them on your projects
• WINDOWS XP, Vista, 7, 8.1 or 10 with Arial and Lucida Console fonts (only FREESPRAY is available for Linux, Apple MacOS X or Google Android but not Chromebooks)
• Simple DOWNLOAD (0.5 to 2Mb EXE file) - no install/set-up, addons, viruses or malware so you can have multiple copies direct from this HTTPS website
• If you have never downloaded programs before from the Internet, then please Email me for detailed instructions specifying the browser / Windows version you have
• Guaranteed NO usage tracking, spyware, toolbars, search engine links, unwanted extra or potentially unwanted programs
• No charges for annual updates, extra copies, training or support by Email
• No personal details ever needed or Email addresses, registration, activation, upselling, tracking, expiry dates, time outs, degrading over time, unlock codes, credit / debit / payment information, advertising or 'in-app' purchases
• You will see that I have always give the extent and scope of the input data needed for the various programs - strangely missing from most other suppliers websites and so you only find out what information is actually needed to perform the full hydraulic calculations for the one or more design areas of your projects until you download them and read the help screens
• All my hydraulics programs are really comprehensive in their features and options but are easy to use with modern intuitive, graphical interfaces, inbuilt help and demonstration examples proved on real projects
• I think that you will find that nobody has produced any NEW software in this field (apart from my programs listed) as they obviously cannot compete with all my FREE ones so if you are waiting for your current supplier to come up with a replacement, you are going to be disappointed
• I, on the other hand, are quite able and willing to DEVELOP any similar sprinkler hydraulic calculations program that you, as an individual or company, may require for your own use (not to sell of course!) - just Email me a full specification (click here for more details)
• I also do not offer any 'paid for' videoes or all day training courses anywhere that overwhelm you with the sheer volume of content - much better to have one of my FREE programs on your PC that you can learn step-by-step at your own pace and I am here by Email should you get 'stuck' at any point or if anything is not clear, all at zero cost
• You get FREE technical support by EMAIL from the same person who wrote these programs but I will never send you an Email, except to reply to your one(s) as I do not have any 'partners' or incentive to sell you anything
• I am not on Facebook, Twitter, LinkedIn, Skype or contactable by telephone
• I do not have any other premium or 'paid for' programs and will never produce software for Building Information Management (BIM / REVIT) systems nor for estimating the operating time of DRY sprinkler systems
• On the other hand, if you think that 'anything free is not worth what you paid for it' then just ignore my programs and buy one from another supplier and see how little different it is!

Thank you for taking the time to read the HOME page of my website - didn't take long, did it?

Why not try out one of my programs; I suggest you start with AACALC8 and FIRSHCP and see how you get on. If you don't like it, just delete it as it did not cost you anything and choose another of my programs or another supplier, if you can find one!

Whether you’re a professional landscaper or want to irrigate your own yard, this free Landscape Sprinkler System Design Tutorial is designed to take you step-by-step through the process of creating a professional-quality sprinkler irrigation plan, layout, or drawing.

There are lots of Sprinkler Design Guides, Why This one?

• This tutorial works with ALL sprinkler products and does not base your design on the use of a single manufacturer or store’s products. Most tutorials will force you into using specific products on your plan. Sometimes they are good products, sometimes not. Bonus: This tutorial will teach you how to spot the really bad irrigation products.
• This tutorial assumes you know nothing about irrigation and breaks it all down for you (but the beginner stuff is easily skimmed over for those more experienced.)
• This tutorial is multi-level. Many of the topics start with a outline of the topic, then expand on that outline in detail for those who need more explanation. Finally some subjects then move on to cover special situations or layout that are not “typical” for those who need that additional insight. So while some tutorial pages are long, you may not need to actually read a lot of it. Unless you are a future irrigation professional and interested in learning all about irrigation, which leads us to the next point…
• This guide is complete. It is used by colleges to teach irrigation design courses, and we encourage that use. However, it is written using 6th grade level English, so don’t panic. If you were ever a broke college student you can probably appreciate the idea of a free online textbook! Speaking of free…
• This tutorial is free. Yes there are some ads, along with a few “tips” they pay the cost of keeping it online. The ads on this site are low key. No flashing ads, no pop-ups (except the “we use cookies” pop-up notice that is required by law.)
• If you have a well and/or pump this is one of the only sprinkler system design guides available anywhere (including those $$$ books for sale at stores) that will show you how to correctly design your system so that it will not destroy your pump by making it cycle or run dry.
• Thousands of people have used this tutorial to create their irrigation systems drawings. This tutorial has been online a while, the first version was written back in 1995. You may find an error or two in it (especially in the grammar, it was written by an irrigation expert, not an English major) but most of the technical errors have been found and corrected long ago. Tons of feedback have resulted in rewrites of the parts that were not clear. The advantage of being online is that the tutorial does get constantly updated to incorporate new products, ideas, and methods.
• This tutorial was written by a professional irrigation designer and licensed landscape architect who has over 35 years experience designing irrigation for everything from small tract yards to golf courses. More on the author at the bottom of this page.

Warning: There are lots of online tutorials and this one may not be your choice and that’s fine. However there are a number of design guides around, both online and in stores, that use outdated design methods. Please watch out for these major design errors that may lead to very expensive repairs:

• Beware of measuring flow with a bucket or gauge. The “GPM” value for your new sprinkler system should be based on the size of the existing water supply pipe running to your house. Some do-it-yourself sprinkler system guides have you measure water flow by turning on an existing faucet and timing how long it takes to fill a bucket. Some also suggest using a special gauge that measures the flow. Regardless of how you measure the flow, we now know that just measuring the flow from a faucet results in major errors that can result in your using a irrigation system flow that is way too high for your house’s plumbing to handle. When you turn on a faucet the water from it will often flow out at a rate that is way higher than what is safe for the pipe’s in your house. While running water for a few minutes at this flow to fill a bucket is relatively harmless, running a sprinkler system at that flow on a regular basis is not. This unsafe high flow results in “water hammer” and “scrubbing” damage to the pipes, two very expensive problems that can destroy the pipes in your house. We are talking thousands of dollars to re-pipe your house! The key here is that when determining the water supply volume the pipe size must be a factor considered.
• Sprinklers should have almost 100% overlap. If a sprinkler layout guide shows you coverage arcs that are not going almost all the way from one sprinkler to the next it is based on the old way of doing things back before we had low-flow sprinklers to conserve water. Almost all experts now agree that there should be near 100% overlap of sprinklers. Back in the old days we just told people with dry spots to run the sprinklers longer. That over-watered 90% of the lawn but it greened up the dry spots. We now know it wastes water and even worse, over-watering causes lots of landscape diseases!

All the information you need to create a sprinkler system design for your lawn, shrubs or garden is in this landscape sprinkler design manual. Illustrations, charts and spreadsheets will help explain and simplify the sprinkler irrigation design process. You will learn about lawn sprinklers, shrub sprinklers, and how to select a quality sprinkler head. Automatic and manual valves, controllers/timers, and the basic hydraulics that apply to watering systems are also covered.

Most of the pages of the tutorial are written as stand-alone articles, so that they will be useful to those who do a search for specific information. For this reason there is a small amount of repetitive material throughout the tutorial.

Free Sprinkler Design Software

Don’t panic! It looks like a lot to cover, but much of it you will skim over because it applies only to very specific situations that don’t matter for most sprinkler systems. (But if it turns out one of those specific situations applies to YOU won’t you be glad that we included it?) You will find that the tutorial goes quickly once you get started. Just take it step-by-step and it is easy.

• Start Here! Introduction to Irrigation Design: How to use this tutorial, information on software programs to design your sprinkler system, and a few suggestions on those “free designs” offered by the sprinkler manufacturing companies.
• Step #1 Collect Information:
  • Measure Your Yard: How to measure your yard easily and accurately for your sprinkler irrigation system.
  • Measuring your water supply (critical that it be done right! One size does NOT fit all.):
    • City-Slicker Water: How to find the PSI and GPM if you get your water through a pipe from a water-company.
    • Country-Bumpkin Water: How to find the PSI and GPM if you pump water from a well, creek, lake, etc..
    • Backwoods Water: How to measure the GPM and PSI for other types of water supplies (Moses would use this section).
• Step #2 Select Your Equipment:
  • Selecting Your Sprinkler Equipment: Pressure loss is the key to selecting sizes!
    • Water Meter: Water meters.
    • Backflow Preventer: How to select a backflow preventer. Do you savor the flavor of dog pee? Nope? You want to get this right!
    • Mainlines: What type of pipe to use and how to calculate pressure loss in an irrigation system mainline.
    • Valves: Types of irrigation valves.
    • Elevation Pressure Loss: How to calculate pressure variations in your irrigation system that are caused by elevation changes.
    • Sprinkler Heads: How to select the best sprinkler heads for your needs. How to avoid the ones that aren’t so hot.
    • Laterals: Type of pipe to use between the valves and sprinkler heads which are called “lateral” pipes.
    • Types of Sprinkler Risers: How to connect your sprinklers to the lateral pipes. Get this wrong and your yard will look like Yellowstone with all the geysers shooting water in the air!
  • Adjustments: Making pressure loss adjustments to balance the system. Boring but very important if you want the sprinklers to actually spray correctly.
• Step #3Figure Out Sprinkler Head Locations: How to determine the correct sprinkler spacing, and which nozzles to use. Where to place the sprinkler heads. The rules on this have changed since the 70’s when a lot of the guidelines online were written. New low water sprinklers make sprinkler layout much more critical. You get this wrong, you get dry spots!
• Step #4 Create Valve Zones and Draw in Pipes: Identify hydro-zones, create valve zones, draw in the sprinkler pipe routes.
• Step #5 Lateral Pipe Sizes: How to calculate the size for each lateral pipe in the irrigation system. There’s no easy way for this one and lots of bad advice on pipe sizes in Internet help forums and the aisles of your local big box hardware store.
• Finished!Some Tips. Automation, Freeze Protection, Costs, Contractors, and of course a whole tutorial on Do-It-Yourself Installation without winding up in the hospital.

About the Author:

So I guess if you’re still with me I’ll switch to first person and introduce myself. My name is Jess Stryker. Unless noted, I am the author of what you are reading on this website. I am a California registered Landscape Architect and opened my own irrigation design firm in 1980. I’ve designed thousands of irrigation systems for everything from little squares of grass in a tiny yard to huge shopping centers, regional parks, and golf courses. Much of my work has been for other Landscape Architects who hired me for tricky projects that required a high level of expertise. In my early years I also did a lot of design for agricultural irrigation systems, like pastures, orchards, vineyards, even dust control and cooling sprinklers for poultry. I’m retired now, which means I’m not interested in designing your irrigation system. I’ve designed enough sprinkler systems for a lifetime! This website is a means of passing along what I’ve learned over the years, and keeping a toe in the irrigation water (pun intended.)

The Sprinkler Design Tutorial began in 1995 during a business slow down. I started writing it not really knowing what I would do with it once it was finished. Shortly thereafter the Internet started to catch on. Back then the Internet was mostly educational works (and porn I suppose) and I figured the tutorial would be a good (education not porn!!!) match, so I put it online. It rapidly grew as I added more and more tutorials and articles on other irrigation topics. (I’ve kept porn off it with one notable exception in the early 2000’s when a link was hijacked and I didn’t catch it for a few days.)

I apologize in advance for my warped sense of humor, which you have already encountered and are about to get a lot more of if you continue. Hopefully it breaks the boredom even if it is just to let out a groan. I hope you enjoy this free tutorial and that you learn a lot from it!
