just a vid on how i set up my herbie overflow using a HOB overflow, its a little on the ugly side but it works like a charm... chose to use a mod. durso because i found it quieter than just a taller standpipe. it seems a little noisy in the vid, but i opened the ball valve a little more and its quiet now *gate valves would of been smarter to use, but i couldnt find any locally, but ball valves work alright*. any questions, dont be scared to ask.
