Pre-Installation Planning: Foundation for Success

How to Measure Your Yard for Sprinklers

Start by mapping your entire property accurately. Property size directly impacts material costs and zone requirements. Walk your yard with a measuring tape and sketch all features.

Include house footprint and dimensions, trees, shrubs, and landscaped areas. Don’t forget driveways, walkways, patios, slopes, hills, and drainage patterns. Mark existing water sources and electrical outlets too.

Use your smartphone’s measurement apps for quick estimates. Then verify with tape measures for accuracy.

Water Pressure Testing for Sprinkler Systems

Proper water pressure ensures optimal sprinkler performance. Here’s how to test it properly.

Attach a pressure gauge to your outdoor faucet. Turn off all indoor water use first. Record pressure at different times throughout the day.

Spray heads work best at 25-35 PSI. Rotary nozzles need 35-50 PSI. Impact sprinklers operate well at 30-70 PSI.

Low pressure below 25 PSI requires pressure-compensating nozzles. High pressure above 70 PSI needs pressure regulators.

Calculating Flow Rate for Your System

Flow rate determines how many sprinklers can run simultaneously. Use this simple test to find yours.

Fill a 5-gallon bucket from your outdoor spigot. Time how long it takes. Divide 5 by the time in minutes for your GPM rate.

If filling takes 2.5 minutes, your flow rate is 2 GPM. Small spray heads need 1-3 GPM each. Medium rotary nozzles require 2-4 GPM each. Large impact sprinklers use 4-8 GPM each.

Sprinkler Zone Planning and Design

How Many Zones Do You Need?

Zone requirements depend on yard size and plant types. Quarter-acre properties typically need 4-6 zones. Half-acre properties require 6-10 zones. Full-acre properties need 10-15 zones.

Irrigation Zone Types

Think about different plant water needs when planning zones.

Turf zones cover grass areas with similar sun exposure. Shrub zones handle trees, bushes, and landscaped beds. Garden zones water vegetable gardens and annual flowers. Specialty zones cover slopes, narrow strips, or unique areas.

Plan separate zones for different plant water needs. Shade areas need less water than full-sun locations.

Head-to-Head Coverage Planning

Proper sprinkler spacing prevents dry spots and overwatering. Follow these spacing guidelines for best results.

Space spray heads 12-15 feet apart maximum. Rotary nozzles should be 18-25 feet apart maximum. Impact sprinklers work best 25-40 feet apart maximum.

Each sprinkler’s spray pattern should reach neighboring sprinklers. This overlap ensures complete coverage without gaps.

Best Sprinkler System Components

Choosing Irrigation Pipes

PVC pipes work best in most climates. They are strong, rigid, and perfect for warm areas. Use larger diameter pipes from 3/4″ to 1 1/4″ to improve pressure. Schedule 40 thickness is recommended for durability.

PVC pipes are easy to cut, fit, and repair when needed.

Polyethylene pipes work as a cold climate alternative. They are flexible and freeze-resistant. However, they are harder to repair than PVC. Rain Bird doesn’t recommend poly for main lines.
