I need help. I'm very slow at learning. "health reasons" Anyway, I think I jumped the gun a little. I let out about 16" of water by useing my pool pump. I switched it to waste. Because I was thinking of having the local pool store come and have my lines blown out. I have a aircompressure and a shop-vac. But I'm nevous I might screw it up somehow. I have a gizzmo, dont know what its for . I'm going to change over my eco-dumb to BBB. "I hope" Im planning on being a supporter and need a good test kit. I also went to user control panel to put in exactly what I have for gear. I dont know what to click on. Sorry for being such a sad case. filix.
