1990 six pac camper sc100

Hello all!..I just joined r.v.net..and have a general question about my camper...my wife and I just bought a 1990 six pac camper..excellent condition...like new on inside..but I can't for the life of me figure out how to drain the fresh water tank..... I've looked everywhere..I've drained the black and gray....but see no valve for the fresh. I would assume you open the gray and just run the pump till it empties..but I do not want to burn the pump up...does this sound right??.I've checked the owners manual..nothing.i have all the manuals for all the equipment on board...it's a shurrflo water pump I believe...

    In my 1986 Six-Pac SC100 there is a drain plug lower left/front side of the tank as you're looking at it. Attached is like 8' of clear hosing with a clamp at the end. I snake that out the back, suck on it just enough to get it flowing and let it do it's thing. I don't know if a previous owner added that or not. It gets all, but maybe 1/2 gallon at the bottom. I usually throw a pinch of bleach in there to keep everything at bay if it's sitting for awhile.

    As a water capacity test I ran the pump for 15 minutes straight once without a problem, but it did get HOT.

    Thanks Tiger4x4RV...I have the original manual and you are right it doesn't say...it just keeps stating drain the water tank after you winterize it or clean it out with bleach and water, then drain(to get remaining bleach out) but says nothing about how to drain lol...oh well...It did say that the water pump is not equipped with an automatic off when the pump gets dry.Ill just open the sink faucet and empty it through the gray tank.

    The only thing that will "burn the pump up" is running it dry. Go ahead and pump it out.

    My camper has a drain on the main tank, but it empties directly into the truck bed, which would not be good for the UNtreated OSB (flakeboard) bottom of my camper. The only option is to pump the tank out through the shower between trips so the water doesn't turn into a science experiment.

    That's what I'm starting to think...my main concern was burning the pump up trying to empty all the water through the sink..

    It might be that it has no drain. I had a 1989 camper (not a SixPac) which was that way.
