While the BB-2000 has a removable nozzle tip, many customers never have to change the tip out. If you have hard water, and are not in the habit of cleaning the bidet regularly, the tip might built up with sediment over time. In situations like this, the tip may need replacing. This is really the only situation where replacing the tip is a must. Long story short, the removable tip on the Bio Bidet Bliss BB-2000 is nice to have, but chances are it won’t be something you’ll end up taking advantage of.
