Bottom Drain
I am in the process of finishing up with my new pond bottom drain. I have
used approximately 30' of 3" ABS pipe from the center of my pond to a gravity fed vortex tank. I am using a TETRA bottom drain which I have enclosed in concrete (2' x 2' x 2'). At a recent water garden show someone told me that I should not have used ABS/PVC pipe because bacteria will form inside the pipes causing them to clog up. Is this true? Also that person stated that flexible pipe should be used instead of the solid pipe. I used ABS as opposed to PVC beacause a plumber friend of mine stated that ABS will withstand the cold weather here in NE. Any comments. One final question: I am using stone dust underneath and around the pipes leading from the bottom drain to mthe vortex. Anyone ever experience using stone dust to fill the bottom of your pond? That is what they use to do inground pools here in NE. Another thought: what are the chances of the bottom drain breacking/splitting at the junction between the concrete and stonedust?
