Another Pump Failure


Another failure with same symptom, wire damage. Look closely at the wire few inches from the pump body, sign of being nibble.

This is the second pump that fail the same way in the same tank, never had happen before. The tank was not new and I had pumps in it before without any problem.

First it happen : Here as photo below.

Initially I thought it was the pump build quality, then could it be the wire chafe against the fibre tank. The pump has been use before and the tank is not new, no failure of this nature.

I know rats love to chew on wire, sometimes we can find them electrocuted while trying to munch through the insulator. But this wire is underwater, and rat don't do scuba dive.

One possibilities... its the Pacu that did it. Only this tank has Pacu fish and I only started doing pacu this year. I never had this problem before.

Wiki on pacu : Here

Photo above from the web of a Pacu fish.


  1. Hi Affnan,

    Maybe if you protect the pump and its cable with some PVC or better with a stainless steel mesh (I don't really like PVC unless it is for waste water), you will find out if the Pacu is guilty or the pump cable is poor quality...

    Thanks again for sharing your experience.


    1. I was thinking of that too, maybe a PVC tubing. But I think it's easier for me to place the Pacu fish in my CRAFTS return tanks. There is no pump in it.

  2. I have had this same problem with all these pumps, usually the plastic on a surface grubbing takes over time. The pump should be free of pay to write my coursework pre-mature wear and tear. See my videos on youtube, I have been making them for 3 years...I will give you another way to open the box otherwise in shipping they placed it back tight enough as to cause damage that can not set right....Use this method if all else fails: REMOVE 24 12V ACTUATOR FROM PUMP, (see page 5 for info) unplug wiring harness kit .

  3. At first I assumed it was the construction of the pump, Dissertationguru Writers but then I wondered whether it might be the wire rubbing against the fiber tank. No such failure has occurred because the pump has been used before and the tank is not brand new.
