Modification to run external pump


Recommended Posts

Hi all ..

Thinking of moving my ehiem pump to run as a external pump rather than submerge in the sump. Can I get away from drilling hole in the sump and just use normal pvc pipe with elbow to connect back to sump and suck water (after I put some water in the pipe for the first run) ?

Possible ?

I got the setup from RC but cant get the link. So I draw out the piping.

I am using this for my skimmer with Rio14HF for ~ 1 + month, so far it perform good. Even if the pump off and on, it will restart the sifon again.

First you will get some microbubble then later it will run smooth after clear all the air in the PVC pipe.

One thing, have to make sure the joint in tight so it wouldnt get the venturi effect and create microbubble in you tank.
