Was it raining? I thought plumbing leak from water heater area on brand new rig. Turned out it was rainwater leak from top of flange where water heater unit is mounted into trailer. Was dripping down and followed plumbing lines on floor. Unit mounted with butyl tape and then sealant around metal flange at outside of trailer but some gaps in that sealant. Ran a good bead of Geocel across top of flange on outside and no more leak.
Same here. Some generous application of silicone fixed the problem on my prior rig. Took while and some thinking to figure it out. My water heater was on the door side, and normally the awing is up, so no leaking when raining. didn't leak until later that summer, when I had to put the awning up due to wind(first time).
