You can operate 2 or 3 sprinklers at one time with 'Y's and extra hoses, depending on your water pressure. To run more than one sprinkler off the same faucet, attach a 'Y' to your faucet and run a hose to each sprinkler.
This will primarily be determined by the total flow rate and pressure you have available at your source. For example, you generally have a flow rate of 10 gpm from a ¾-inch spigot where you connect your hose. With your 10 gpm flow rate at your spigot, you could run two sprinklers at 5 gpm each.
If all your sprinklers flow rates are 1GPM you can add 3 of them on the same line to run simultaneously. If you need more sprinklers you can set them up on a separate hose and run them at a different time, essentially creating sprinkler zones.
The rules vary by system type. Pipe-schedule systems and hydraulically calculated systems with a density at or over 0.25 gallons per minute per square foot have a 12-foot (3.7 meters) maximum distance between sprinklers. Hydraulically calculated systems with less density have the standard 15-foot (4.6-meter) maximum.
A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”. This requires sprinklers to be positioned away from obstructions a minimum or three times the maximum dimension of the obstruction.
The high volume pressurised water stream gets harder to be distributed evenly. Thus, that size of impact sprinklers have another small (4-6 mm) nozzle to water the area for the closer area to the sprinkler. The main stream will start spreading in the air after a certain distance to the sprinkler head.
One sprinkler does the job pretty well. And while my setup doesn't reach the edges of my yard, I do have the option of installing up to three additional Quick-Snap sprinklers down the road. These can either be daisy-chained together to function as one unit or used independently when needed.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter.
Daisy chain connectivity
Multiple sprinklers can be joined to increase coverage distance. Look for Flow through connection feature on the sprinklers to join multiple sprinklers.
My recommendation is to bury sprinkler lines 8-12 inches. I usually try to keep a standard depth of 10" because it provides more safety if I need to do some type of ground work so I don't have to worry about hitting lines. A walk-behind rototiller generally won't go deeper than 8".
The optimum operating pressure for most residential sprinkler heads is between 30 and 50 pounds per square inch (PSI). With correct water pressure, each head will perform the way they were designed, and the result will be even spray-patterns and efficient use of water.
System maintenance can help save you a lot of money and water! Cracks in pipes can lead to costly leaks, and broken sprinkler heads can waste water and money. You could be losing up to 25,000 gallons of water and $280 over a six-month irrigation season! Now is the perfect time to spruce up your irrigation system.
Not more than 1000 automatic sprinklers shall be controlled by any one preaction valve.
Meaning that spray heads should never be placed further than 15 ft. apart as this would create dry spots (i.e. dead grass) in your lawn. It is always important to install sprinklers with overlap for full coverage. Spray heads have a higher application rate than other sprinkler heads.
Most residential plumbing systems are designed to handle 40 to 60 PSI of pressure, with 80 PSI being the typical maximum and anything over 100 PSI being possibly detrimental to plumbing components.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.
The pressure level can vary, but 60 PSI (pounds per square inch) is recommended for most residential homes. Water pressure should not be higher than 80 PSI. Anything higher can cause major appliances, including water heaters and toilets, to stop working properly because of the stress on plumbing and other parts.
This depends on the flow rate you are able to achieve from your water source. Calculate your flow rate using the bucket test, then reference the flow consumption of the pop-up sprinkler. E.g. If you have a 45lpm flow rate, you can run 7.5 half circle professional sprinklers as they use 6 lpm (45 / 6 = 7.5).
Hook up a sprinkler booster pump for your hose.
All you do is hook your hose up to the pump, and then hook another hose up that runs from the pump to the sprinkler. Plug the pump in and turn the water on. The pump will artificially force water out of your weak water line at a much higher psi.
Don't water your grass before mowing. Wet grass tends to clump together on the lawn which could suffocate the grass underneath or promote fungal growth. Also, it could clog up your mower. Mowing is an essential aspect of home maintenance.
Water up to 25 minutes for rotors, rotary, and impact sprinklers. Tips for new seed: Keep the top 2 inches of soil moist watering daily, morning would be best to get it through the heat of the day.
