no hot water flow

Here's a good one.
I have a 2005 29' Wildcat 5th wheel. I brought it out of storage and de- winterized it.I filled the water heater by bleeding the air out through the pressure relief and fired it up. When I turned on the sink tap there was no water flow on the hot side! I double checked the bypass valve. It was in the correct position for water flow to the tank. There was something blocking the line and after some dissassembly I found the problem. There is a check valve on the Hot side of the tank that closes when the bypass is used for winterizing so there is no backflow into the tank through the hot side. It is a plastic piece with an o-ring seal inside a brass fitting. There is a retaining clip of some sort ( I guess) on the tank side that keeps it from coming out so far that it actually blocks off water flow out of the water heater. This clip or retainer was gone! So I removed the piece with the o-ring and had hot water flow again. I searched for a replacement check valve and have had no luck even finding a mention of such a thing. I noticed on some of the newer RV's they are using valves on both the cold and hot sides of the water heater now when you bypass. Guess I'll have to do some re-plumbing before I winterize again.
Any one else had this problem? Can someone tell me where to get a new water heater anti backflow valve????? It's a suburban 6 gal. water heater.

Can you describe the exact location of this check valve? I have a problem with no hot water to my kitchen sink (but I DO have hot water to the bathroom sink and shower) and I figure there must be a check valve somewhere but I cannot locate it.
