water bladder cleaning and manual pump repair

[xluke]

Hello,
First, I have a water bladder that has had stagnant water in it for a while and I'd like to flush it out and clean it -- what is the recommended procedure for doing this? I presume some concentration of clorox but I'm open to any suggestions.

Also, I have a manual hand pump at the sink that isn't working (the galley sink doesn't work but the bathroom does, so I do not think it is a plumbing pressure issue). Is there anything that can go wrong that can be repaired with a manual hand pump faucet? I already took the bottom off and found a small rubber "valve" that appeared to be in good shape. I flipped it over and it didn't change anything...
When I pump it it seems to just move the water back and forth in the clear plastic line from the bladder to the sink, like it isn't holding the vacuum.

Thanks!

C-Brite or B-Brite are commercial cleaners/disinfectants restaurants use and work well.
A winemaking supply shop will have them.

The same type "valve" should be also on the top. Check that one also.
