JDM Posted September 17, 2006 Report Share Posted September 17, 2006 drill a hole just below the water level in the display, this will suck air in and stop the syphon as the level drops below the hole. Quote Link to comment Share on other sites More sharing options...

suphew Posted September 17, 2006 Report Share Posted September 17, 2006 check valves reduce flow alot and are prone to not working once algae etc builds up in them. anti-syphon hole is the way to go. Quote Link to comment Share on other sites More sharing options...
