Recreational vehicles are not just an investment; they also express an individual lifestyle. Additionally, everything must function perfectly. If a Dometic CT 3000 or 4000 toilet model has been improperly installed by a previous owner or is showing its age, don’t replace it—revitalize it instead. With the Dometic replacement kit, you can swap out essential components, saving both money and time while ensuring a clean, hygienic, and reliable toilet. Easy replacement, clean and hygienic. Package includes: waste tank, toilet seat with lid, flush ring cover.
