Return pump noisy

[kamino]

Hi brothers,

Since about 2 months ago, my Ehim 1262 return pump become noisy. Not sure if it is my imagination but the flow rate seems to slow down. Everytime I adjust the return pump abit, the noise my subside for awhile then returns. I feel may be some part is loose?

Any advice? or are there tank maker or maintenance guy to engage for help? Unfortuantely I am not a handy guy

Try to soak Ehiem pump, or take out and water. Maybe got salt or Ca deposit on the pump that cause it like that.

You have to take out the pump and check the impeller and hosing of the pump. Something could be broken or calcium deposit. It's good habit to wash your Pumps every 6 months to prolong the life span. If you are not sure how to do it, either sought help from reefer friends or engage the service of tank makers found on our sponsors' section.

Usually it is cost by dirty pump impeller. Try removing them and clean them. It may just solve your problem.
