That sounds like my problem just a bummer I didn't buy a thick sound proof material because my hole is drilled straight on. Would it be worth plumbing that pump on the concrete floor or not worth the extra head? Also sucks that shelf is screwed right to the wall my couch is on you can hear everything that's why I'm thinking just use the smaller dart and run no manifold off my main display pump buy a smaller pump for manifold. Thanks for the help
