12 Volt Caravan Water Pumps, Filters & Accumulators

Keep Water Flowing Smoothly in Your Caravan

When travelling off-grid, a dependable caravan water pump keeps your sink, shower, and washing setup working like home. Many caravans use 12-volt water pumps to keep water pressure steady without draining the battery. Without the right pump, pressure drops and the motor may wear out early.

Outback Equipment stocks a wide range of caravan water pumps and accessories designed for Australian conditions. Choose a compact hand pump for a simple setup or an automatic Shurflo or Seaflo product for a full plumbed water system. Match flow rate (litres per minute) and PSI rating to your layout to keep water supply consistent at every tap.

Caravan Water Pump FAQs

What flow rate is best for a caravan water pump?

ChatGPT said:

Most caravans use a 12-volt water pump that moves 10 to 12 litres per minute. This flow keeps the sink, shower, and toilet running at the same time without losing pressure. A Shurflo 4009 or Seaflo RV Supreme MK2 suits most setups, while the Outback Explorer 3.8 L pump works well for smaller portable systems. Pick a pump that matches your setup so your caravan water system runs smoothly on every trip.

What PSI should a caravan water pump have?

A 12-volt water pump rated between 35 and 45 PSI gives reliable water flow. The Shurflo 4009, for example, cuts off automatically at 45 PSI to protect your water system and maintain consistent pressure.

Do I need an accumulator with my water pump?

An accumulator helps keep water pressure steady and reduces how often your pump turns on and off. This makes the caravan water system run more quietly and helps the pump last longer. It’s a good idea to use one in larger setups or where you notice pulsing at the sink or shower. Many new 12-volt water pumps already include internal bypass systems, but adding an accumulator can still make the flow smoother and the operation more consistent.

Can I use mains water at caravan parks?

Yes, you can use mains water at caravan parks. Attach a pressure regulator to your caravan water inlet to stop high pressure from damaging fittings or seals. Mains water can reach 80 PSI, so keeping it around 45 PSI protects your pump and hot water system. You can shop caravan water inlets at our site.
