JayFlight 224BH hot water heater bypass valve location?

[wordsmyth]

So it's time to winterize the bunkhouse. I've watched a half dozen videos, but I've not yet located the bypass valves for the water heater.

Can someone (in particular another 224BH owner if on the boards) point me to the location of those valves?

Thanks in advance,

Rick

I'm not 100% familiar with your floorplan, but is your water heater located below the bottom bunk? If so, there should be an access door under the lower mattress.

That was it. Thanks.

Here are the steps I followed.

1. Drain water heater
2. If still open, close the outside low point drains.
3. Close the valves that bypass water heater. On the 224BH the access door is at the rear of the cargo space underneath the bottom bunk.
4. Turn the valve on the water pump to allow antifreeze to be siphoned into the system
5. Insert siphon tube into the antifreeze jug
6. Starting with the faucet furthest away from the water pump, turn on the water pump and open the faucets to siphon anti-freeze into the lines. Working around, open the hot, then the cold side of all faucets in the trailer until pink fluid is flowing freely. On ours I followed this order: shower, toilet, bathroom sink, kitchen sink, outside sink, outside shower.
7. Dump a bit of antifreeze into each sink to fill the p-traps
8. Back at the pump; turn the siphon valve back to its original position.
9. Gently pry the screen and rubber washer out of the city water connection, then stand aside and press the tip of the white valve inside fitting. This release the pressure on the system.
10. Reinstall the hot water heater plug.

The notes above are compiled from two YouTube videos.

Crawling under the bunk was the worse part. There's a catywampus photo below of the access door at the back of the compartment underneath the lower bunk. I'm working on some additional photos and may come back later via edit and include them.

Any thoughts on this for the 2023 and later models that use a tankless water heater?

Not much on these systems yet online (YouTube).

I assume no bypass and I can just ignore the water heater (leave it off) and follow same steps as you've shown above?
