We supply a 15mm alkathene hose which is connected to an outside tap. There is a one off water hose hire fee of $5 per metre for the duration of the cabin hire. The use of typical garden hoses is illegal due to toxicity.
Tank water is fine so long as a pressure pump is in use instead of a gravity feed from a header tank. The pressure required is a minimum of 25psi and a maximum of 75psi, with a minimum flow rate of 5 litres per minute.
