When it comes to buying water pumps and filters for your RV, there are several factors to consider. You should consider the flow rate, which is the amount of water that can be pumped out in one minute. Flow rates above two hundred liters per minute are best, and smaller units should have a flow rate of 100 to 200 liters per minute. You can also consider the type of filter you want to use. Some pumps come with built-in filters. The pump style filter usually has a prefilter on the end of the hose to filter out biologicals and suspended solids.

In addition to the pump, you might also need other accessories such as check valves, float switches, water alarms, replacement wheels, hydraulic power unit, impellor kit, and control box. You should always consider the size and price of your water pump before purchasing it. Also, consider the pump's power source, as some may have more powerful engines. A gas-powered pump can work for a more mobile situation. When purchasing a water pump, you should also consider the maximum head, which refers to the highest height the pump can reach. A pump that can't reach more than 60 meters will not be able to work properly, and will result in zero flow. So make sure to purchase a pump that has a higher maximum head than you plan to use it. Lastly, consider the brand of the pump, as it can indicate the quality of the water pump.
