Frequently Asked Questions (FAQ) and Troubleshooting

Have technical doubts? Here are answers to common questions from users and professionals. A knowledge base to avoid classic mistakes and optimize your system.

How do I calculate available pressure for my system?

To calculate static pressure, you need a gauge on the tap. For dynamic pressure (what really counts), measure while water flows. An empirical method is the 'bucket test': fill a 10L bucket and time it. SprinklerMap helps convert this data into operating capacity.

What is 'Head-to-Head' overlap and why is it important?

It's the golden rule of irrigation: a sprinkler's throw must reach the adjacent head (100% overlap). Rain from a sprinkler isn't uniform: it's heavy near the head and drops off. Overlap compensates for this, ensuring uniformity (DU).

Can I mix spray and rotor sprinklers in the same zone?

Absolutely not. Sprays have high precipitation (e.g. 40mm/h), rotors low (e.g. 10mm/h). Running them together for 20 mins floods spray areas and leaves rotor areas dry. Separate them into different zones.

How much does SprinklerMap cost?

SprinklerMap offers a free mode for basic design. Advanced features like Auto Sprinkler, material export, and precise overlap calculation are Premium features for professional results without costly errors.

How do I configure Auto Sprinkler for irregular shapes?

The algorithm works best with clean perimeters. For 'L' or 'U' shapes, try virtually splitting into rectangles or focus on manual placement for difficult corners, letting the algorithm fill central areas.

Does the software calculate pipe pressure loss?

Currently SprinklerMap focuses on placement and coverage. Pipe sizing requires complex hydraulic calcs depending on elevation and fittings. However, we provide a linear estimate of tubing needed for your bill of materials.

Can I import a satellite map of my garden?

Yes, GPS mode and Editor mode allow using Google Maps as background. You can trace your garden directly over the satellite view for maximum precision.

What if sprinklers don't cover some corners?

Corners are critical. Always start by placing sprinklers in corners (Corner Strategy). If one is missing, you'll likely have a dry spot. Use adjustables (VAN) to match the exact angle (90°, 120°, etc).

How to choose between drip and pop-ups?

Use pop-ups for lawn, needing uniform large-scale coverage. Use drip for hedges, gardens, flowerbeds, pots, where water must go to roots without wetting leaves (reducing disease and waste).

Is a rain sensor mandatory?

In many municipalities it's mandatory for new systems. Regardless, it pays for itself in one season by avoiding useless watering.

How many sprinklers on one line?

Depends on available flow (l/min) and individual sprinkler consumption. Sum the consumption of each nozzle: total must not exceed 80-90% of available flow at operating pressure. SprinklerMap helps visualize total zone consumption.

Best time to water?

Sunrise (4:00 - 6:00 AM). Evening encourages fungus as grass stays wet all night. Day evaporates too much. At sunrise, water penetrates, leaves dry with sun, optimal cycle.

Are SprinklerMap weather data reliable?

We use global weather APIs for ET estimates, but microclimate varies. Treat our data as a professional starting point to refine with direct observation.

Can I use well water?

Yes, recommended. But ensure you filter it if it contains sand/debris, which clog nozzles and valves quickly.

How to do winter maintenance?

Winterization (blowing out) is vital in freezing zones. Expanding ice breaks pipes and heads. Use a compressor to blow water out before freezes.

Why does my lawn have round brown spots?

Often fungus, but if geometric, likely a malfunction or poor coverage (bad overlap). Check Distribution Uniformity.

Should I put gravel under sprinklers?

Yes, a small gravel drainage bed under the body helps stability and drainage, preventing sinking into mud over time.

What pipe diameter?

For residential, 25mm (3/4") or 32mm (1") is standard for main lines. Smaller pipes cause huge friction loss, reducing pressure at end sprinklers.

What is water hammer and how to avoid it?

The bang when water stops suddenly. Can break pipes. Avoid by designing non-excessive water speeds (under 1.5 m/s) and using slow-closing valves.

Does SprinklerMap work on iPad/Tablet?

Absolutely. The interface is responsive and designing on a large touch screen is the ideal experience.
