Buying Guide – How to Choose the Best 12v Water Pump for RV
Selecting the right pump depends on several factors that affect performance and compatibility with your current setup.
Flow Rate
Flow rate measured in gallons per minute determines how quickly water moves through your system. A higher flow is better for multiple fixtures but uses more power.
