Hi, i have got home to take a no.2; flushed and now I have floaters 😂. The other half is saying its been blocked all day except it was going down after a few mins. Its now been about an hour since its been filled. Any advice? Or how much it will cost a plumber to unblock? I live in a top floor apartment with 2 kids. Could the kids have put something down there and thats why its not going down? Or is it just an over flowing of poop n tissue 😂
