Hi folks - I have a basic rotomold water tank under my trailer. It will not be used for for drinking water, just cold water to the sink for dishes. It's like this one:

Still, seems like it should be cleaned out between trips. What's the best way to do this? I can add a valve to one of the spouts but gravity alone won't empty the tank. Any suggestions?
