The toilet in our master bathroom has the undesirable habit of clogging and then overflowing. Using the plunger has corrected this problem thus far, but I am getting increasingly concerned that we may have a bigger problem. Our neighborhood is famous for its septic issues and I am worried that this may be an indicator that we are developing a serious problem. We did have the septic pumped out six months ago after another back up that was indeed because of a full septic tank. However, this is the only toilet in the house that backs up, we have not had similar experiences in the other bathroom, kitchen, or even the other drains in our master bath. Any suggestions as to the cause and/or remedy?
