Whether or not blocked drains are covered by home insurance in Australia can depend on your specific policy and the cause of the blockage. Generally, if the blockage is due to normal wear and tear, it may not be covered. However, if the blockage is caused by a sudden and unexpected event, such as a tree root intrusion or a broken pipe, it may be covered under your insurance policy. It’s important to review your policy and speak with your insurance provider to understand what is covered and what isn’t. It’s also recommended to regularly maintain your drains to prevent blockages and potential damage to your home.
