Caravan Water Pump FAQs

How do I know which water pump I need for my caravan?

Choosing the right water pump for your caravan depends on several factors, including the size of your water system, the pressure requirements of your appliances, and your water usage habits. Consider the following:

  • Flow rate: Measured in litres per minute (LPM), a higher flow rate is needed for larger systems or if you require more water simultaneously.
  • Pressure: Measured in pounds per square inch (PSI), ensure the pump meets the pressure requirements of your caravan’s appliances.
  • Voltage: Most caravan pumps operate on 12V, but ensure compatibility with your caravan’s electrical system.
  • Type: Diaphragm pumps are common and suitable for most caravans, but submersible pumps might be preferred for certain setups. Consult with manufacturers or specialists and consider your specific needs to find the ideal pump.

Can you leave the water pump on in my caravan?

Yes, you can leave the water pump on in your caravan, especially if you’re using the caravan or need regular access to water. Modern water pumps are designed to be pressure-sensitive; they automatically start when a tap is opened and stop when it’s closed, thanks to an internal pressure switch. However, it’s advisable to turn it off when the caravan is not in use for extended periods or when you’re disconnected from a water source to avoid unnecessary wear and dry running.

Are all caravan water pumps the same?

No, caravan water pumps are not all the same. They differ in type, size, flow rate, pressure output, and power consumption. The two main types are:

  • Diaphragm pumps: These are external pumps that pressurise the water system and are known for durability and efficiency.
  • Submersible pumps: These are placed inside the water tank and are quieter but may have a lower pressure output. Choosing the right pump depends on your caravan’s specific water needs and system setup.

Do caravan water pumps work off a battery?

Yes, most caravan water pumps are designed to work off a 12V battery system, which makes them suitable for use in off-grid situations where mains power is not available. Ensure your caravan battery is in good condition and adequately charged to power the water pump effectively.

How do I know what size water pump I need?

The size of the water pump you need for your caravan is determined by its flow rate and pressure capabilities, which should match your water usage and the requirements of your water fixtures. To determine the right size:

  • Calculate total flow rate: Add up the flow rates of all fixtures that might be used simultaneously.
  • Consider pressure requirements: Ensure the pump can achieve the required pressure for your system to function correctly.
  • Consult with experts: When in doubt, consult with a caravan supply store or a plumber experienced in caravan setups for personalised advice.

How do you get air out of a caravan water pump?

Air trapped in the water pump or lines can cause the pump to run poorly or become noisy. To remove air:

  1. Fill the water tank and ensure all connections are tight.
  2. Open the faucet closest to the pump and turn the pump on. This allows water to flow through the system, pushing air out.
  3. Open other faucets one at a time to purge air from different sections of the plumbing.
  4. Run the pump: Allow the pump to run until water flows smoothly from all faucets without sputtering, indicating that most air has been expelled.
  5. If the problem persists, check for leaks or loose connections that might be allowing air into the system.
