I purchased the ddc pump with the ek top and res and it worked fine for two days. I went away for two week and came back and it would not long pump. It took it apart and the impeller will spin without the pump top but as soon as I put ek top on it act like its gripping and will only turn every few seconds. I can't see where the problem is. Anyone else have this problem.
