Gilmour Lawn Sprinkler

Hello,
I have a Gilmour portable lawn sprinkler model 7700PM and I am trying to find out what the gallons per hour would be at 65 lbs water pressure. I contacted customer service and they do not have that information.
Can anyone give me an estimate?

To many variables....hose size and length for instance. Put it in a 5 gal bucket marked with 1 or 2 gallon levels, turn it on and time how long it takes to reach slightly above one of the lines...do the math to reach one hour of run time..that will be your gph.

You can't do it with just the hose end since the sprinkler will add some restriction to flow.

HI,

Your best bet is to aim the sprinkler in a 5 gallon container, and see how long it takes to fill it.

300 divided by the seconds it takes to fill a 5 gallon bucket = GPM
