Hello,
I have a JEBO pump that is 75w and rated for 6000liters which is more than adequate for my pond (that I just inherited when I moved)...it was working fine but now it almost seems like it has lost power. Here are some notes:
1) It is submersible
2) It was working just fine
3) Then working very weak
4) Pump "grate or casing" was removed and cleaned so no obstructions
5) Water has to climb less than a meter (3 feet)
6) When I tested it, the higher I lift the outlet hose the lower the power
7) Tried situating as shallow as I can but that added 20cm max
8) I moved it around to see if it was an air bubble
9) Tried a Bestway pool pump while I was trouble shooting but I could not get the external pump and filter to suck water up from the pond despite it only being less than 30cm above the water
Any advice for a noob pond owner would be greatly appreciated
