What is the difference between the Crown Head II and the Atlantes?

The Atlantes is an all-ceramic unit with the mechanism contained within the confines of the bowl. The Crown Head II has a molded plastic cover over the macerator and discharge pump at the bottom of the head. Additionally it uses a remote-mounted intake pump or solenoid valve, usually mounted below deck. Both units contain a built in macerator.

What is the noise level of the Crown Head II?

The discharge pump and macerator, situated directly beneath the bowl are very quiet, comparable to a home toilet. The intake pump is somewhat noisier but is remotely mounted, usually below deck. Freshwater flush models are virtually noise free. All CHII models are significantly quieter than Crown Head original series.

What is the difference between the Crown Head II and the Crown Head.

The major difference between the two is that the intake pump on the rear of the Crown Head has been removed, mounted on its own motor and mounted remotely.

The discharge pump and macerator are the same.

A minor difference is the appearance: The Crown Head II uses a streamlined lower cover or skirt, whereas the Crown Head uses a square lower cover.

The Crown Head has a built-in deodorant siphon system, the Crown Head II does not - it requires the addition of Raritan's optional Toilet Water Kit (TWK) if this feature is desired.

The Crown Head II has available, as an option, a Deluxe control system that allows timed flush, momentary flush or dry bowl flush, as desired. The Crown Head may only be configured for momentary or timed flush - no dry bowl flush is available.
