I have a problem with my septic drain field - water is being pumped out of the sand filter tank and it's getting to the manifold, but it's not going into the drain field, so the water level in the tank stays the same. I had the laterals jetted and scoped to confirm that at least one line was clear all the way to the ball valve (and that ball valve is open). Still, no water comes out of any of the 5 laterals. The techs claim that the pump is underpowered because the previous Zoeller N-137 died and was replaced by an N-152 which has lower GPM. But it still pumps a lot of water and there's a lot of water pressure all the way to the ball valves.
Does anyone have any ideas of what might be the issue and what to try next? I find it hard to believe that it's the pump because the rate isn't THAT much lower than the N-137, and the water isn't even trickling through. And it's going to cost $1500-$2000 to replace the pump - without knowing if it's even causing the problem.
