I have recently started the BBB method about a month or so ago. Had a swamp. Now I have a sparkling beautiful pool thanks to everyone on here. My problem is I have some trash, leaves, etc. clogging up my main drain. Turned it off, sent my nephew down to see what he could do. Hurt his ears. So Saturday, I sent my 19 year old daughter down. She has helped with this in the past. She also could not stay down very long because it hurt her ears. She couldnt pick anything out, so I sent her down with a butter knife to poke through. She said she only could get some of it. But after she did that, I am having lots of trouble with air being pulled in when I turned the main drain back on. So not only do I still have trash clogged up in the holes, I think she may have lodged something in the pipe. (not her fault, I sent her down there). But, does anybody have any suggestions on how to unclog the main drain? And I should add, diving to the bottom also hurts my ears. I will be willing to suffer it if I can figure out something that will work. Please help!!
