Review on Dometic 385310683 Spring Cartridge Toilets by Scott Yenson

There is a difference between black cap and white cap with spring cartridge. Of course, the first set I bought with the ball set was wrong. So I had to buy these separately. The foot pedal drive cam on the side of the cover is larger for the black device and smaller for the white device, and the foot pedal design does not work interchangeably with them. Before you buy, look under the drive lever cover on your toilet bowl for a white or black toilet bowl. This assembly is placed between the toilet and the water valve, and the screws go through the valve first and then through the spring cartridge to attach it to the toilet.
