There could be multiple reasons for the toilet leaking, it may be the supply line connection at the water valve. It might be the vacuum breaker that leaks whenever you flush the toilet, or the water module, depending on model. Here is a link to the manual https://www.rvupgradestore.com/v/vspfiles/assets/pdf/Bravura-Manual.pdf
on page 2 there is a troubleshooting guide for leaks. If you are able to identify exactly where the leak is occurring I should be able to find you the correct replacement part. Thanks.
