In my 302, there is an access panel in the toilet room with a black box with the following:
"B&B model 571"
It doesn't seem to be a valve at all. Numerous searches reveal nothing.
Is there a valve somewhere else?

Water heater bypass valves will be on the back side (inside) of your water heater.
Not all water heaters come equipped from the factory with a bypass setup. They can be easily added after market.
Here is an example of what to look for...this is a 3 valve system. Some are two valves and even one valve. (note, the valves in this picture are all open..which is incorrect)

Here is a follow-up to my previous post...
If you find that you don't have a bypass system - you can easily add one like this for about $25...any RV parts outfit, dealer or Camping World.

Some manufacturers don't have bypass systems as standard equipment. It's possible yours is one of those. If you have good access to the heater it's not that big of a job to install one. Your OTHER option is to just buy an extra 6 gallons (or 10 gallons) of antifreeze and fill the water heater along with the rest of the plumbing.

I'm pretty sure Keystone uses by-pass valves on all their trailers. Mine is similar to this but with one valve.
They are located directly on the back of the heater.
I think you have a 12 gal. heater, so filling with antifreeze is out of the question. $$$$$ Some heater tanks can react with antifreeze and should not be filled. Check the paper-work that came with your trailer to be safe.

I found this on the back of my heater. As you said, I have one valve. So what keeps the water from going into the heater on the hot side?

Dan,
There should be another valve..look close to the tank on the cold water inlet.

I am assuming there is a check valve in the heater itself. There is only one external valve and the system works fine.

Yeah, there must be an internal check valve on the water out.The valve in the photo is on the cold in.

Did you try a search on Google ???
A quick search there and you will find out that B&B Model 571 is a "Tank Flusher" for cleaning out "stuff" from your black tank.

As others said check the backside area of your Water heater for the bypass valve. I would be shocked if a Fuzion didn't have one standard.
