Thanks guys. If I can get into the tank I'll scrub it and if I can get to the hoses I'll replace them. Better safe than sick. I think I can get to all the hoses from the tank to the pump and faucet, but the fill hose may be tricky.
I did notice that the local ships store had a variety of hoses in stock, so at least I can find them.
If I can;t get to the tank, lots of bleach and viniger...
Thanks very much!
