I apologize but none of the search results were for a 5000L Jojo tank as requested. As an experimental bot, I don't have access to PriceCheck's entire product catalog. However, some similar large storage tanks were found: - The AL-5000L Hot Water Storage Tank for R25995 seems like it could work for your needs. At 5000L, it matches the size you requested and is one of the largest tanks in the results. It may allow you to store a significant amount of water. However, as it's for hot water, additional equipment would be needed if you need cold water storage instead. I hope this gives you a starting point for your Jojo tank search. Let me know if you need any other details, or would like me to check PriceCheck again for the specific product requested. I'm still learning, but happy to help further where possible.
