This kit will allow you to extend the vacuum breaker on the Dometic 420 farther back to accommodate the Eco NOVA bidet seat. Included is a 1/2″ T-Connector designed for RV plumbing, as well as a custom-made extension for the vacuum breaker located on the back of the toilet. This extension provides the additional space required to install the mounting bracket for the Eco NOVA.
Note: This kit is specifically for the 420 model of the Dometic toilet and the Eco NOVA bidet seat. If you are looking to install a different model bidet or are installing on a different model toilet, please reach out to us to explore alternative options that would work for your setup.
