Rainmain,
I was thinking of having the multiple vent holes in the smaller pipe if there was some type of build up that might happen because it is buried that I hadn’t taken into consideration when starting and stopping the siphon. If I am overthinking this a smaller pipe cut a few inches above normal pool buried might be the better option. In the drawing it shows covering the larger pipe with rock and some type of trash guard. What would you suggest as an ideal buried setup for an Automatic siphon system?
Thanks!
Heppy
