I am working on planning the replacement of our old Wilcox-Crittenden Headmate toilet.   I have been looking at the Raritan PH Powerflush as I like the idea that it can be used as manual toilet if there was any problems with the electric flush.   There are previous posts about others using Raritan PH II, Sea Era and/or Marine Elegance models.   

Has anybody installed the PH Powerflush model?  Or researched it and rejected it for some reason that I might not be aware of.

Thanks
John
