Water heater drain plug? Trailer about 21 years old.

Trailer about 21 years old and I have never removed the plastic drain plug on my Atwood water heater.  Do you think if I remove that "nylon" plug and flush out the water heater I will be able to rein...

I think you have been extremely lucky. There’s an old Navy saying that our rusty ships are held together by paint. Your water heater may be held together by crud. If you decide to flush be ready for a possible full replacement.
