The small white "flow indicator" check-valve-ball in the Ehiem 2022/2028 series is the same as in the Ecco series. The replacement for the Ecco costs $4; the replacement for the 202x series cost about 4 times as much. The ball housings are very diff and a new one needlessly comes with the replacment ball. The housing hardly ever wears out or breaks -- it would be a neat trick to break one -- you'd have to try. But the balls can get beaten up bouncing around the output tube and they deteriorate over time. So, if you need to replace the ball on you 202x series filter, get the part for the Ecco, toss the housing in the wastebasket and save yourself about $12.
