Water heater leak

[Snappy298]

I have a new jayco class c water heater leaks at times at rear of heater lines are dry only leaks when hot Dometic heater any ideas

[craigav]

I would tighten the water inlet and outlet connections at the water heater. Many times the heat allows for expansion and therefore they only leak (usually only a drip type of leak) when hot. ~CA (btw, not too tight, I think they are plastic, hand tight first, then if needed use a tool (pliers perhaps) but only tighten slightly and enough to stop the leaking, for sure and to repeat, do not overtighten these lines as doing so will break the plastic there and that requires you to replace what broke).

I have tried hand righting hot and cold I will try with players see if that works thanks

Check tightness of all waterline connections like the bypass valves. Depending on floor plan may be hard to get to.
