Well the answer to that is yes.The RV pump is what creates and pressurizes.and makes the water move.So the rating on a pump,say five gallon a minute or 3.3 gallon per minute,is the output capacity of the pump.Now once you hook it up to your distribution system,you’re not gonna get 3.5 or 5 gallons per minute.because the water gonna travel through pipe,it’s gonna travel through elbows and fittings and your faucet fixture,and it maybe less than that.But the important thing is that you have enough flow and enough pressure to be very workable in your RV.
