When my trailer was new we discovered a drip at the water pump.
There was a stainless automotive type clamp there but it was not
Also found a bigger drip at the water heater. A screw on fitting at the inlet
was just finger tight.
My first trailer blew off the water line at the pump. Luckily we were
in there at the time and heard the pump suddenly start running and
quickly found the flood and shut off the pump. Again it was a loose
screw clamp at the pump outlet.
Every trailer I've owned leaked somewhere or other when they were new.
Seems like they get tired at the assembly line and loose plumbing fittings
Glad you found yours right away!
Now go camping and
