Fresh water pump question
In the near future, before all the prices go up due to the increased tariffs, I am going to purchase a spare fresh water pump. The question is: is there a reason or downside to getting a larger one than is currently installed? Going from a 3 gph to a 4 or 5 gph? Other than the higher cost what else might go wrong? They appear to be the same, except for the higher amperage draw. Am I missing something?
