This is the lowest flow rate water pump we could find, but still claims to be 8-10 litres per minute.

We don’t know exactly how water is going to work in the van yet – how much we’ll use stored water on tap. But we expect it to be minimal, and as the flow rate from these switched pumps can’t be adjusted, we want to use as little as possible at a time.

Even with this pump we could empty a 25 litre water container in 2–3 minutes.

So we’ll see how it goes. We might end up swapping it for a manual pump if this is overkill.
