Fresh water tank

We have a 2016 Cruiser Aire 5th wheel and are having issues with the fresh water tank leaking from the connection coming out of the tank. Is there any type of sealant that will stick to this type of plastic tank?

Had the same issue with 2014 Cruiser, used marine grade silicone to patch around the bung where it was dripping, and 2yrs later itís leak free. I also added a piece of aluminum channel across the frame under the tank to stop any sagging or movement of the tank, not sure that is what caused the leak, but we boondock a lot so travel with a full tank. Be sure to clean area thoroughly and apply a thick coat and allow to cure before use.

Did a quick Google search for "RV water tank repair" and there a lot of videos on you tube and a lot of different products. I personally have not had to repair one so cant recommend one product over another. Please let us know what product or method you use so if someone else has this problem it may help them.

Failed Water Tank Fitting

We just experienced a total failure of the drain line fitting on the water tank of our 2015 Cruiser 5th Wheel, which has about 5,000 road miles on it. We purchased the unit new. It appears that the failure is due to stress cracking caused by a ridged connection of the drain line to the under belly cover. The drain line was manufactured with a significant "glob" of adhesive where the drain line penetrates the under belly cover. This ridged connection appears to have created a situation where the probable constant movement of the underbelly cover as the trailer is being towed transferred that movement to the tank fitting. Since we are having a very difficult time locating a new tank with similar connection layouts, we are hopeful that the repair shop can reattach the fitting using a "weld" of the ABS Plastic, which is literally melting ABS plastic around the fitting. My guess is that there are many Cruisers on the road that will experience the same failure.
