Thank you. 6 Jan 2001 at 10:30 pm #289561 Glenda FlyParticipant I am a plumber in Texas that does new construction. The problem is that you need a new wax ring. I is under your commode. You can pull up your commode, replace it, and it will be good to go for a few years. It is not hard to do. Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
