Before starting your sprinkler system design you’ll need to take a couple of readings from your outdoor spigot.
Water Pressure Reading (PSI)
Optimum performance of your Lawn Belt sprinklers is based on 40-60 psi (pounds per square inch). If you are operating a water pressure between 30-40 psi our Water Saver Kit operates well within this range.
Use a pressure gauge (available in our store or locally for about $8) This will give you the most accurate reading at your spigot.
Optionally you can call your local water company and ask them for the PSI at your meter.
Pressure Reading (attach gauge at the spigot)
If attaching a gauge make sure all water sources both inside and outside the house are turned off. Then simply attach the gauge to the spigot and open the faucet fully. For a more accurate reading test two or three times during the time you’ll be watering.
Gallons Per Minute Reading (GPM)
Can you fill a bucket in 8-9 seconds?
The suggested GPM for your Lawn Belt sprinkler system is 8 GPM (gallons per minute).
Here’s a quick and easy method to checking your GPM. Get a gallon bucket and open your spigot all the way. If you can fill the bucket in less than 10 seconds you have enough GPM.
You can also apply the following formula:
60 / Seconds to fill 1 gallon
For example if it takes 7 seconds to fill a gallon then divided 60 by 7.. or 8.6 GPM. This number is then divided by the number of heads in the kit (3). The ending result should greater than 2 for each sprinkler head.
Note: Some newer spigots have a higher restriction on the flow – meaning that your GPM reading may be slightly lower than actual.
Check your numbers using our sprinkler calculator
Lastly you’ll want to visit our sprinkler calculator page to calculate your GPM with our sprinkler heads and the length of your zone.
