Dobber, Since you are in GA you should give the folks at pond dam piping (Macon) a call. I've always ordered my fittings from them for all the siphon systems I've helped install. I'm sure since they are a paid advertiser in POnd Boss they would appreciate it. For other folks asking you can see a diagram of the siphon system at their website. www.ponddampiping.com
Good luck, Greg www.lakework.com
