My 400D is leaking fluid out the 90 degree elbow of the exhaust. I've checked all the lines and can't find a leak anywhere. I'm wondering if I should pull the burner out and check there.Called aqua hot and couldn't get anyone to offer any advise except buy a new unit.I don't mind paying someone to look it over but I'm in a small town in west PA and don't really trust anyone here that I know. Would travel for an experienced tech. Not parts changer, I can do that myself. Any thoughts or suggestions. Unit has only been used 10 or 12 times. Was winterized properly.

If NOT winterized properly, the fluid would leak out the overflow reservoir when water pump or city water was connected. If you have fluid leaking out that elbow, have you smelled that fluid? A non firing diesel burner will leak out excess diesel at that elbow. The ONLY way to verify a bad weld or inner tank crack is to pull the Aqua Hot and remove the various outer shells and insulation. If this is the case the ONLY fix is to buy a new unit or send back to Aqua Hot for a rebuild. Doug

It WAS winterized properly. This is my 11th RV and not my first aqua hot. I never hook up to city water. I use pump only. It fires up perfectly and works on electric also. Fluid leaking is definitely boiler fluid. I replaced 3.5 gallons of it in a week. Hard to believe this unit is bad with so little use.

zb, call me between 8 and 8 central and I will help you sort this out. I am a Authorized Aqua Hot Service Center, so I have 14 years experience to call upon to assist you. But what you are describing does not sound like a minor repair. But a few questions will solve that.You do not need a new heater and that expense. So call me and lets see what we can deterine.Rudy Legett 7 one 3 8 one 8 3234
