The bypass valves should be right by the water heater. My WH is in the rear pass side corner. To access the bypass valves I have to move the mattress in the rear bedroom, and reach through a hole in the bed frame and another hole under the corner cabinet by the bed. The WH is drained and bypassed when winterizing so it doesn't freeze and explode. It should stay bypassed and drained until it's needed again so it's not surprizing that you've had it over a year and it was drained and bypassed(it was still winterized from the PO)and you haven't needed it till now.
Wherever the WH just search around the other side and you should find the access to the valves.

It has been my experience that the bypass valve is usually located pretty close to the water heater. Depending on your water heater location, I would look in the closet, behind drawers, behind a closed panel, etc. If you have an owners manual I would think there would be a section in it that would tell you where it is located.

Your "House" owner's manual SHOULD tell you the location of the valve(s)

There are 3 different types of bypass systems. one rare, two common

3-Valve.. Look for a letter "H" made out of pipe, This will likely be lying on it's side on teh "Back side' (inside) of the heater, you have to remove a panel or open a door to access it, With the heater being on "TOP" of the H there will be 3 valves, on each in the "Cross bar" and the top halves of the two legs.

The cross valve should be closed, If it has an oval head this is NORMALLY with the long axis of the oval across the pipe (KEY WORD NORMALLY NOthing etched in stone)

The other two valves should be open (Long axis NORMALLY in line with pipe)

The other system is a "Single valve" this is a 3-way valve and all bets are off as to which setting is which.

The rare system is a 2 valve,, basically it's the same as the 3 way but they used two single way valves and a "T". (Home made 3-way)
Home is where I park it!

So Stupid question are you hooked up to city water? when trying to fill tank?

or are you running water pump and is there water in the freshwater tank? the bypass valve is on the backside of the water heater. or also on your model where you hook up the water there will be a valve that says winterize make sure this is turned to normal. not all units like yours have this but its worth a shot. I work on motorhomes everyday so hopefully you get this worked out i know how frustrting it can be

Think the OP figured out his problem and does not want to share the oops. It now 425+ days, but what the rush. Didn't know there was a problem for over a year. I'll stay subscribed - expect answer in six months or so. Just my damn two cents...

If he fired it up empty he will probably need to look somewhere else for a warm shower.

Anyone that fires up a hot water heater without first checking to make sure there is water in the tank should look for a different recreational activity versus owning a RV.

That's the quickest way to damage the hot water system but it does keep the Camping World's in business.
