![]() I would try throttling back your return pump.......I have HOB over flow that claims to be rated for 1200 gph, and I tried everything to make it quite.
The only thing that worked for me was to back off the return pump to about half. Here is a great article on reducing the noise from your overflow http://www.wetwebmedia.com/SystemPIX...Oneinchart.htm Hope that helps |
