# Where do you put sprinkler heads?

Rectangular Areas

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.

Subsequently, question is, how high should sprinkler heads be? The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.

Keeping this in consideration, can you mix sprinkler heads?

If you set that same irrigation zone to run based on the precipitation rate for your spray heads, well then they’ll have an adequate amount of water, but the areas with the rotors or rotary nozzles are going to be severely underwatered, so you don’t want to mix them.

How many sprinklers can I run on one line?

The resulting number will equal how many zones you need. If, for example, each sprinkler head will require a flow rate of 1.31 GPM and you have 20 of them, then you will need 26.2 GPM total. If your system can only handle 16.67, you will need to use two zones to cover that same area of your yard.

### Do it yourself install sprinkler system?

Table of Contents Step 1: Plan the System. Step 2: Access the Water Line. Step 3: Dig the Trench. Step 4: Install the Valve Manifold. Step 5: Run the PVC Pipe. Step 6: Install the Sprinkler Heads. Step 7: Install the Controller.

### What size pipe should I use for a sprinkler system?

When you install a sprinkler system, you might use PVC or polyethylene piping to deliver water to the sprinkler heads. If you use PVC, the typical diameter of the pipes is between 1/2 inch and 2 inches. The right size pipe depends on the overall capacity of your system.

### How many sprinklers do I need per square foot?

In the case of the extended coverage heads the square footage can range between 144-196 square feet per sprinkler head. The most important application when using extended coverage heads is based on the recent testing using the EC-25 sprinklers.

### How Much Should sprinklers overlap?

Sprinklers are intentionally designed to require 100% overlap of watered areas. That means each sprinkler throws water ALL the way to the next sprinkler in each direction. READ THAT AGAIN! That’s right, 100% overlap of watered areas is REQUIRED or you will get dry spots!

Dig a trench from the new valve to the locations for the new sprinkler heads. The trenches should be 2 to 3 inches below the average depth of frozen ground in the area, or a minimum of 6 inches deep. Cut into the PVC pipe wherever a sprinkler head will be used and install a “T” fitting and a threaded sprinkler riser.

### How do I increase water pressure in my sprinkler system?

Adjust Your Pressure Loss Data: Increase the mainline size. Lower the sprinkler head operating pressure. Reduce the pressure loss in the laterals. Increase the size of the backflow preventer or valves. Lower the Initial Design Flow. Add a booster pump to increase the water pressure.

### How do I increase the pressure on my sprinkler system?

Remove a few sprinkler heads from each of the zones in your system and cap the plumbing that led to them. Decreasing the number of sprinkler heads will increase the water pressure in those that remain. Install a boost pump on the main irrigation line.

### How much water pressure do I need for a sprinkler system?

The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi. You can measure the water pressure at your site with a flow meter or water gauge attached to an outdoor faucet.

### How long should sprinklers run in each zone?

Try this: Cut in half the amount of time you water each zone, but run your watering program twice. In other words, instead of watering each zone for 30 minutes, water each zone for 15 minutes, then cycle through all the zones again for another 15 minutes.

### How much does it cost to put in a sprinkler system?

Both Key and Allen say the typical yard they deal with is about a quarter-acre in size and the sprinkler systems cost about \$2,500 to \$3,500 to install. Allen says the cost to install sprinklers on half-acre lawns runs \$3,500 to \$5,500, and one-acre properties cost \$6,000 to \$8,000.

### Can one sprinkler valve control two zones?

Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
