  • Failed after 3 weeks of use By on 4/7/2016

    Maybe I just got a bad one, Mine failed after less that 3 weeks of use. I contacted cobalt directly, they said I should soak the impeller in vinegar for an hour, I did that it still did not work. Soaked it for a full day. Still did not work. Called cobalt back and they said they would send a new impeller. That was almost four weeks ago, still no new impeller

    These are tried and true workhorse pumps. I use them for multiple purposes and they are extremely dependable and quiet. The Cobalt brand is much quieter and the build quality is superior to the Marineland version.
