I am looking to replace the standard 1.0 flood jets on a RotoVac 360i. I looked Jon-Don's parts section and saw 0.75, 1.0 and 1.5 flood jets.

I have been using the original jets (1.0) for about a year. I would like replace them with 1.0 because I am not looking to experiment with new sizes.

This situation has got me curious to know as much as I can about jet sizes. What does the jet size number (0.75, 1.0, 1.5, etc.) mean? What would be a benefit to go to a larger or smaller jet? What other factors need to be considered when choosing a jet size?

Thanks TMF

There all the same the flow rate is at 4000 psi just different jet shapes
So a 2 flow jet will flow 2 gallons at 4000 psi or 1 gallon at 2000 psi or 1/2 gallon at 1000 psi and 1/4 gallon at 500 psi

Aprox flow not real life not much difference tho

So 6. 2 flow jets at 500 psi will be around 1 1/2 gallons per minute

I always thought there was a difference in how flood jets and vee/tee jets were rated. I have an old original steamway wand with a #3 flood jet, so you're saying that it is the equivalent of a #3 tee/vee jet

My understanding is the flow rating is done the same as TeeJet or VeeJet. The pattern and angle are different.

The only difference between v t and flood jets are were the water comes out and the spray pattern that's it They are all sized the same for what ever they are rated for

So if you have one of each and let's say all 3 of them are 5 flow all 3 jets will flow the same amount of water just have different spray patterns at the same psi

Flood jets are not rated the same
page c4 #3 veejet orifice size .043
page c22 #3 teejet orifice size .043
page c30 #3 floodjet orifice size .057 (approx 30% larger opening)

A # 3 flood jet is equivalent to a # 5 vee or tee jet
