Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Cleaning out my pond- Overflow pipe questions

Thanks for the reply. If I use a siphon style overflow would I still need to use anti seep collars? Also, would it be a good idea to put in a traditional style overflow pipe for backup in case it gets clogged ect? I like the idea of a siphon style so I would not have to dig much of the dam.
