Pump hums but water doesn't move, after cleaning: the replacement pump.
Lost the spout or a holder broke: the accessories kit.

Filter schedule

Swap the cartridge and sponge every 1–2 weeks. One cat on a two-week rhythm uses a 6-pack in about three months; several cats on a weekly rhythm go through a 12-pack in the same time.
