I recently extended my tunze by about 15’ from the ato water to my sump. I used stranded 14 AWG wire and 1/4” drip irrigation tube. There is a vertical rise of ~5’. When I first turned it on it worked no problem. After it’s initial cycle I raised the sensor in my sump, the controller will turn the pump on but no water will flow. I check the pump and it’s making noise but nothing is pumping. Even if I pull the 1/4” tube out noting is pumping. Any ideas?
