Fresh Water Valves?

Can someone confirm where these two valves drain from? Why is there rust - dripping over the years? I am nervous about simply taking pliers to these two valves! I have a 2002 Classic. There is a third valve - that I think is the fresh water tank drain. Click image for larger version

Plastic is fresh water tank drain. The others are water system low point drains. Might want to spray PB BLASTER or similar on threads and take it easy turning them.

Did just that. CCW gently turn with 10 inch vice grips and they opened easily. Wish I knew where to get new ones - even just the inner valve screw. Thoughts?

I've never replaced any, but they look just like petcocks or drain cocks. The unknown is the connection to the plumbing system. Drain cocks are pipe thread. You may not just want to turn out w/o making sure the fitting is secured and your not turning against the pipe.

FW Plastic Drain valve

Check out my previous post from a few months ago. The plastic valve is fragile and I suggest popping it out by pressing from the bottom rather than trying to turn it. There are a few great ideas in previous posts by others to improve reliability. Best attempted when the weather is agreeable and you can improve the trailer height.
