Dometic CTS 4110 Spare Cassette

The ventilation hole has changed from earlier models to provide a better seal. The part that actuates the ventilation connection is a removable white part on the toilet base. This part is included with new cassettes.

Optionally you may remove the ventilation outlet from the old tank and place it in the new tank by rotating 45 degrees. However this will not improve the ventilation seal.

Suits:  Dometic CTS-3110* and CTS-4410 Cassette Toilets  (*CTS-3110 is the previous model to the CTS-4110)
