We recently got some Apex 25-foot long (½-inch in diameter) blue hoses from Walmart that are supposed to be safe for drinking purposes. However, when I first turn it on in order to water my plants and such, the water seems fizzy or foamy for about twenty seconds each time (well, once a day or so). Is this really safe for me or my plants? I'm not sure if this will continue indefinitely, but it's been three or four weeks, now. I have three of them hooked together (but it still foamed with two). Our old hoses never did that, and they probably weren't meant for drinking.
Edit: The site asked me if the other question solved my problem. It is a similar question, but it didn't solve the issue, as my question was specifically about the fizzy/foamy quality of the water from a specific kind of hose—not about the safety/toxicity garden hoses generally, without regard to fizziness/foaminess (and without regard to whether the hose is advertised as safe for drinking). So, I can't honestly say the other Q/A answered my question (although I do understand if others feel they are too similar to keep apart, or if they don't feel the question is a good one to remain open).
