Re: 2016 Bullet HW bypass
I have the 2017 272BHSWE and I found the Hot Water Heater Bypass access in the rear storage.
There was a cut out leading to underneath the bunkbed, then I was able to remove that small cutout and reach the single valve that bypasses the water heater and sends cold water right back down the hot water lines.
When I checked under the bunkbed mattress, the bed frame/wood was securely fastened and i would need to damage/cut/ruin the bunkbed to gain access to water heater valves...
Assume there is that newer one-way flow switch built into these models so, a single turn to open/close the valve...
