ok, so the toilets in my house all overflowed this am, because I had a clog in the main part of my drain - under the house apparently, I had a plumber here for a an hour and a half this am. It was all backed up with tampons. ewwww I nearly gagged when he showed me!! Do you flush tampons? He told me I never should flush them. They get caught up in the cast iron pipes at the bottom of the drain. I have lived in my house for 12 years - never had that problem before! Glad I know now before my 3 daughters hit puberty!!
