dont know..most likely yes
This sprinkler does not rotate.
Just turn the top to which adjusts to any spray area
The rubber hose size diameter can vary. The coupling with threads is standard, i.e. the one end of a garden hose will naturally fit on the water source faucet from the house, while the other end will attach universally to the simple thread of the unit. I have used this sprinkler at various locations with different fatter and thinner hose diameters and it makes little difference. The amount of volume one lets by turning faucet on high or low will affect the broadcast area a well as the quickness of saturation.
I don't know about flow rate, I have no way to measure. I am on metered water and am careful about usage. I set a square pattern on mine so it covers my whole space but only that space. This is quite easy.. I only need a small amount of water pressure to do this. If I turn up the pressure it will cover quite a distance. I turn it on in the evening and wait until it has done a good job and then turn it off.
At least in my case the water comes out pretty hard. I got one of the cheap ring type sprinklers that works good.
It has easy to use adjustable spray patterns.
I haven't had any leaks. I use the rectangular setting to water that little strip between the sidewalk and road, without wasting water. I just need to adjust the distance based on the spray.
