After months of dealing with a noisy return pump in my sump I've finally found a way to get it nearly silent. I have a Marineland NJ1800 and it started out fairly quiet but now 9 months later it has a noticeable loud hum. First, I took it apart and cleaned it really well, and made sure there was nothing in the pump or on the impeller. After that failed, I worked with Marineland to replace the impeller under warranty. That helped a lot but even after there was still a pretty noticeable hum that was about to drive me crazy. :headwallblue: I was to the point that I was about to order a new pump and throw mine out.
This morning I took a sandwich bag and filled it full of pool filter sand, double bagged to keep it from getting busted in my sump, and placed it under the return pump. Voila! Instant quiet. The hum is gone! :celeb1:
