Check the impeller shaft for wear also. Its not uncommon for tiny

Ok, just need to buy the parts.

Check out the Maxi-Jet line of powerheads. They have quite reasonable
flow and head rates and are very dependable and cheap. Or the Danner
line of Mag Drive or small POndmaster by Danner which also have very
respectable head and pressure values, better than the typical pumps
found in use with factory made filters of any brand. The Maxi Jet and
Danner brands are all submersible and the Maxi-'s are smaller than the
average coffee cup is and rated at 1200 GPH and put little to no
latent heat back into a aquarium which is also a plus in a lot of
cases. Both are pretty darn cheap to buy as well. I use a lot of the
Maxi-Jet 1200 and 900 sized powerheads for pushing water to sumps etc
on my various setups and the smaller 400 and 600 Maxi and the even
smaller 404 etc for current making in the tanks, or pulling water out
for water changes. Just a nice small all around dependable pump that
works as advertised for a long time. Stay away from the Aqua Clear and
Hydor powerheads. Aqua Clar may make a gread HOB filter but their line
of powerheads suck in regards to longevity of use and flow and head
rates.
