SRC Member vinccc2009 Posted March 4, 2011 SRC Member Share Posted March 4, 2011 Is there a way to reduce the humping sound of the return pipe? Or the sound is from the vibration of the piping? Any bros any advise? Quote Link to comment Share on other sites More sharing options...
SRC Member tunicate Posted March 4, 2011 SRC Member Share Posted March 4, 2011 Are you running your pump in-sump, or out-sump? Quote Link to comment Share on other sites More sharing options...
SRC Member tunicate Posted March 4, 2011 SRC Member Share Posted March 4, 2011 BTW, it should be "humming", not "humping". Quote Link to comment Share on other sites More sharing options...
SRC Member vinccc2009 Posted March 4, 2011 Author SRC Member Share Posted March 4, 2011 My ehim 1264 is outside the sump. I place it on a cushion. Top up is fixed with PVC pipe all the way to my main tank above. I can feel the vibration is at this pipe. But how to reduce this humming... Read that some change to rubber hose n it solve this noise...any advantage of PVC piping and rubber hose? Quote Link to comment Share on other sites More sharing options...

I suggest u put a short rubber hose after pump return outlet than join with the pvc pipe. This shd reduce the humming sound.

SRC Member tunicate Posted March 5, 2011 SRC Member Share Posted March 5, 2011 The longer the hose, the better the cushion from vibration. Quote Link to comment Share on other sites More sharing options...
acidjc Posted March 5, 2011 Share Posted March 5, 2011 The humming is basically from the pump, because of it high flow rate. It cannot be reduce much. By putting rubber hose before PVC pipe will reduce vibration noise. Do also check is your pump or pipe are touching any part of the tank or cabinet, if it does, this will generate noise If you really cannot stand the humming then replace your pump with 2 smaller one. Smaller produce less noise.
