Our 1995 45' Newell has developed a slow leak in the waste tank. The tank is pretty well concealed and hard to look for the leak. Is there an easy way to locate the leak? All I know is that water is coming out from under the tank and leaks out the compartment door. Is there something that can repair the leak without locating it? What am I going to do to get this thing fixed? The coach is for sale and might have to give an allowance to repair this, how much allowance should I give?
The most common problem is a Zap electronic odor control probe corroding and then leaking. The probes are located near the bottom of the tank. You can pull the carpeted board between the tanks, the tanks must be empty, and see the probes. If it is one of the center probes the tank will have to be pulled to repair it. You can replace the probes with plugs, as ordor control is not necessary on late model coaches with toilets that have a water seal.
