Waterlife Posted March 1, 2023 Share Posted March 1, 2023 FX6 pulsating after cleaning and maintenance. There’s a knocking sound inside it too, maybe the pulsating is bumping things around in there. It’s not an air issue, it’s sealed and valves are open. There’s very little water coming out sporadically in small pulses to nothing at all. It’s been fine for 18 months. many ideas?

AndEEss Posted March 1, 2023 Share Posted March 1, 2023 Did you properly prime it before starting it back up? Link to comment Share on other sites More sharing options...
Waterlife Posted March 1, 2023 Author Share Posted March 1, 2023 Yes I filled it to the top. Link to comment Share on other sites More sharing options...

Waterlife Posted March 1, 2023 Author Share Posted March 1, 2023 Yes both lines are filled. There is a knocking sound coming from the motor with every pulse, no water flowing out. But the lines are pulsing like it’s trying to pump water. Link to comment Share on other sites More sharing options...
mynameisnobody Posted March 2, 2023 Share Posted March 2, 2023 @Waterlife I’d check the impeller. It may need a good cleaning. 1 Link to comment Share on other sites More sharing options...
ColBud Posted March 2, 2023 Share Posted March 2, 2023 Second on checking the impeller. Not sure on fx6 I don’t use that but make sure any cover over it is in place and the impeller is seated properly. 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted March 2, 2023 Share Posted March 2, 2023 The noise you're hearing is air being hit by the impeller. Even if you purge it perfectly there's a few things going on.... A. You might need to clean the pump / impeller so that the flow i strong enough that it can push out the bubbles. B. You might need to rock or angle the canister itself to push the air out of crevices and then let the pump push it out. C. A pinhole in the tubes that is pushing air into the canister. 1 Link to comment Share on other sites More sharing options...
Rewcolee1 Posted March 2, 2023 Share Posted March 2, 2023 (edited) I’d check the impeller as well. I typically have to replace mine every 18-24 months. It’s cheap and easy and certainly knocks the db’s down. Edited March 4, 2023 by Rewcolee1 1 Link to comment Share on other sites More sharing options...
Luciferkrist Posted March 2, 2023 Share Posted March 2, 2023 I support checking the impeller. When I set mine up last year it was doing the same thing and it ended up being a snapped impeller shaft. Dropped a new one in and works like a charm. 1 Link to comment Share on other sites More sharing options...
