I've been using a 2 litre High Sierra's water bladder to go underwater to practice drinking in fishland. Could do it fine and comfortably. I had quite a bit left over from Sunday's session so I took a sniff at the water a few days later and it smelt chemicalish. I could have sworn that I'd washed it properly with mild bleach and rinsed it thoroughly including giving the hose a good flush too.
Anyway, today I tried again. Filled it with a few hundred ml of water, went to the pool and BEFORE I donned the gear, took a sip. Didn't taste too right but never mind. Poured it away, flushed it for some time and filled it up with bottled drinking water. After I came out of the pool, I could have sworn again that it tasted chemicalish. Could the valve have allowed some of the swimming pool water to leak in?
