Hot water service anodes should be checked annually and replaced when worn. If you need advice on water system components for your caravan, our team can help.
Frequently Asked Questions
What size water tank do I need?
It depends on how long you want to be self-sufficient between fill-ups and how many people are using the water. We stock 85L and 160L tanks. Many caravans run two tanks for increased capacity.
How often should I replace the water filter?
Follow the manufacturer's recommendations, which typically range from every 6 to 12 months depending on usage. If you notice reduced water pressure at the taps, the filter may need replacing sooner.
Do the water tanks come with mounting hardware?
Yes. The Melbourne Rotomould water tanks include fittings and straps for mounting. Check the tank dimensions against your available chassis space before ordering.
