Ira Posted April 23, 2006 Report Share Posted April 23, 2006 I find my durso pretty easy to tune. Tighten air valve water level drops. Open air valve water level rises. The whistling from the valves is pretty noisy though. I keep meaning to throw some airline into them and throw the ends into the sump where it would be contained a bit...

cracker Posted April 23, 2006 Author Report Share Posted April 23, 2006 another way is to place some open weave foam up the durso head to muffle the air...it might help. Quote Link to comment Share on other sites More sharing options...
