Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Leaking, rotted outlet pipe

Any repair to the old one seems like it has limited life. I still feel the siphon drain is the way to go for the ideal overflow pipe. The line thru the dam is not buried down deep into the core of the dam so if there are any future problems with it would not drain your entire pond. You put that in and seal off the old one. Gotta wonder what the cost of that is versus the cost of a repair that will last ten+/- years.
