Hi, I am not new to RVing but I am new to this platform. Believe me...every year and every season I learn more and more about this 'hobby'. We just finished to unwinterize our unit and during the last walk around the rig before we completed for the day I noticed this hissing noise coming from behind the water heater and behind the sink. Everything was in the OFF position. I cannot figure out what/why and if this was drawing power. I never noticed this before and cannot tell if this is an anomaly. Is this supposed to be like and/ or for how long this should continue?

Your comments are welcome.

Thanks!
