Pond Boss Forums POND CONSTRUCTION Building a dam 24" Corrugated Pipe/Fittings

I have not used the belled end pipe that you show. I have used single walled pipe with a 90� coupling that was zip tied together. I liberally coated the whole inside of the fitting with roofing mastic before attaching it to the two pieces of pipe and burying it 4' under ground. I have not noticed it leak but can't tell for sure because the way the water level is inside and outside of my pond.
