low pH bathroom faucet water

Low pH yet mild water is a mild antibacterial. Low pH water can be produced with electrolysis, so faucets could be electrified to produce water that is say, 10x better at being antibacterial

The talk of being conservative with antibacterials at bathroom handwashing made me think, well, wouldn't that objection go with regular soap? So pH modified faucet water is even milder than soap, yet antibacterial. Sanitation has saved lots of lives so this could be a mild extension of that.

       How low are we talking here? Battery acid?

       Great idea, although it's possible that regular washing with very low pH water might not be suitable for people with sensitive skin - or any skin, in fact

       Vinegar is indeed an effective biocide, but it doesn't kill all bacteria and viruses ... chlorine is much better at that.

       What is “faucet water”? Well, I know what water is, and I know who Farrah Fawcett was, but what type of water is that?

       Tap water, [IT]. He only speaks a form of american (pidgin) English ... more deserving of pity than condemnation...

       // very low pH water might not be suitable for people with sensitive skin - or any skin//   

       A quick search verifies that an electric gradient can create a temporary pH gradient so if you arrange electrodes into a kind of filter, all the water will go through a gradient and return to normal pH once exiting the filter. If the water isn't conductive enough, a circuit could regulate voltage. The DARPA article I found though wasn't clear on the amount of bubbling generated so the antibacterial properties could have the side effect of making tap water flammable.   

       All that said, you might as well blast the water with UV.

       I recently visited quite a large city in eastern Europe, which built its old town 200 metres from the foot of their large and active hilltop cemetery. With EU funds (150 million euro plus), they recently had to update their public water system, but I still contend, like the Romans, who had a law against it, that you don't mix cemetries on hills and city centres.   

       The little link shows a WHO test procedure for testing elimination efficacy re viruses which get through pipe seals. Turns out that anything less than 99% is unacceptable, which is like saying that eating raw chlorine is delicious.

       [+] although somehow the idea of electrified faucets sounds like a not so good idea.
