Water heater bypass 27bhs???
Can anyone help me figure out if there is a water heater bypass on the jay flight 27bhs? We just bought a 2017 and I wanted to sanitize the water system. But I can't for the life of me find a by pass for the water heater?
The access panel is in the back of the trailer. But there are no bypass valves that I can see.

Typically HWH bypass valves are on the "back side" inside the RV.
In some cases the owner's manual may have more detail and information needed.

Lots of TT's I have seen, the valves are in front where the cold and hot water pipes enter the water heater. Should be 3 valves.
Sometimes you have to almost stand on your head to reach them.

From what I can tell there is no inside access. It's a bunkhouse and the "inside" of the water heater is behind the outside kitchen and under the bottom bunk. There's not a panel to access from inside that I can find.

Got to get to them from the inside of the tt. Often you need a #2 screw driver to remove a panel. Find the water heater outside. Then look inside in that same place. Mine was under the dinette bench, access from above, screwed down. I have seem them behind a cabinet door, that is screwed shut. When you find it, I'd recommend leaving the screw(s) out.
Pull the matress, and I bet you need to remove part of the board the matress is on.

It would be behind the outside fridge which is screwed down. I guess I can remove it and see what's back behind it.

in my TT you can lift the bottom of the bed up and it gives me a direct shot to the bypass valves. I just lift up the mattress and the plywood for the bunk is exposed lift up the plywood and it is a direct shot to the back of the hot water heater.

Found it!
Unscrewed the fridge and looked behind. Then I saw a little access panel that looked like it was under the bottom bunk. Then it occurred to me to remove the bottom bunk mattress and there was a hidden loft up door that gave access to that panel from inside. That's how you get to the bypass valves.

Now the issue is that there aren't three valves. There are two. I assume I just switch both of them to activate the bypass?

If you can't find the 3 rd valve you don't have a bypass.

first of all apologies to you for the PDI guy not showing you the location.. i always show the back side of water heaters to customers so they know where and what there looking @. i believe on your unit its in the back under the bottom bunk. i could be wrong. if so you will need to lift up the bunk board to access it.

Agree on the location. It does not need to be adjacent to the other 2 valves. You just have to find it and figure out the valve positions as shown in the diagram I posted.
The newer fifth wheels with the utility closet make you spoiled.

My 28bhbe only has 2 valves as well. But I can tell you it does bypass the heater. How do I know? After blowing out all of the water I turned the valves and then ran antifreeze through the system. When done I opened up the pressure relief valve on the wster heater and only got air.
However my Greyhawk had a triple valve bypass. Go figure....
