Well its time for me to replace my livewell pump. Replaced my 500 Lph Rule with an 800 Lph and its way to loud. Has anyone ever removed theirs from the flow-rite valve? I know they screw in, but my also is sealed with some black sealant that is making this a difficult process. I'd like to know if I'm wasting my time or if it is even possible. Would appreciate any info...
