I have come upon a pair of Eheim 2215 filters. Both make much more noise
than I
expected, and not even close to the near-silent running of a 2224 that I
use. Pump
output seems quite normal.
Right off I replaced the obviously worn rotors with new ones. The ceramic
shaft
and rubber bu****ngs that sup****t it seemed in good condition and not worn.
I
cleaned the impeller housing carefully, and have repeated the dissassembly
and
cleaning without improvement.
I can feel more vibration on the top cover of the 2215 than with other
canisters
that I have used. The noise goes down noticeably by pressing down slightly
on the
top. Perhaps it is rattling slightly due to vibration.
Is this typical of the series, or should it be better ?
