I used this to get rid of the constant dripping noise from my reverse osmosis sewer line. It was so loud I could hear it in another room. It doesn't stop the noise completely, but like its function, it limits it when enough pressure is released in the reserve tank and the system refills and I happen to be in the kitchen or when I have something under the sink and I'm trying to hear it flow. My system is a WP-50 watt with a 50 gpd filter. Get one with the right flow for your system.
