I’m trying to understand why rinsing down siding with my 4000 psi, 4 gpm pressurewasher is faster than using a garden hose, since the pressure washer is connected to the garden hose. The way i see it the gpm at the end of the garden hose is still the same. So apart from getting more pressure and apart from shooting further, does it really rinse faster? And would it be worth it carrying a tote for rinsing water for residential just to cut down on rinsing time by not being limited by the customer’s spigot? For example using a 7 gpm 12 volt pump from tote seems like it would rinse faster since more volume at 7 gpm than 4…
What are the fastest ways to rinse (12 volt pump, x-jet, shooter tip, other pump…)?
And any tips and advice specifically to cut down rinsing time?
