Pump Capacity or GPM

The GPM of the RV water pump changes as per the pressure of the machine. Therefore, while considering buying this tool, you will need to determine the amount of water you can generate through the pump. Do not choose a unit with more GPM if you do not have that many needs. However, if you have a larger RV, you can consider buying a machine with a 5-GPM capacity.

Water Pressure

The next you need to consider is the pressure of the flow. Check the pressure before deciding on the RV water pump. While you would know the required pressure for your RV, ideally, the experts recommend around 60-75 PSI for RV use.

Voltage Unit

Depending on your RV size and the amount of water you will need, you will have to choose a model for your RV accordingly. However, keep in mind that higher voltage units are for heavy-duty jobs, whereas lower voltage machines are suitable for small tasks.

Automated Pump Cycle

It is one of the most important considerations that many buyers overlook. When you are choosing a water pump, make sure it has an automatic pumping cycle. This unit will offer seamless operation, and you will not need to operate it manually.

Noise Level
