Does anyone know anything about plumbing? At least one of our toilets (usually in the kids bathroom) backs up almost every day. Of course, we assume they are just using too much TP or whatever but occasionally the garbage disposal backs up into the other side (we have a split sink). If drains right away as soon as I turn it off and it doesn't happen every time but I am wondering if both of these things are a signal that something is going on in the pipes somewhere? Happy to call a plumber if that is what's needed just not sure .
