The nozzle has a snug fit on the Spray Collar and will require slight arm muscle. This tight fit was intentional so that the sprayer setting could be adjusted from the sanitary outside of the Spray Collar.

The Spray Collar fits without taking the Bumkins ring off – this is just an alternative installation hack. The ring hanger on the Bumkins sprayer serves no intentional purpose anyway. 

Most cloth diaper brands get their sprayers from the same manufacturer. For example, the Blueberry Flo diaper sprayer is the same as the OsoCozy diaper sprayer.

The Bumgenius Sprayer is the same as the original Aquaus sprayer, and the Spray Pal sprayer is the same as the Bumkins.
