My 337 unit is about 8 months old, last week I noticed water on the floor near the electric panel door; pulled the lower middle drawer and was able to see into the compartment housing the hot water unit and saw that the outlet hose had ballooned just past the clamp and was leaking. The hose is rated at 150psi, but when hot it is very soft and water pressure greater than 50psi causes the diameter of the hose to expand. The hose walls are quite thin, and do not appear to be very robust for trailer usage. Has anyone else had any issues with water leaks and/or hose replacements?
