Drinking water is supposed to keep moving in the pipes. It gets treated with chlorine (or other chemicals) when it leaves the treatment plant, which protects the water during its trip from the treatment plant to your house… but the treatment process can’t kill 100% of pathogens in the water, nor can it do anything about pathogens that might get into the pipes via tiny cracks.
If the water spends too much time in the pipes, it warms up, which makes it a friendlier environment for pathogens to multiply. It also gives those pathogens more time to multiply. If the water pressure is low, that means you aren’t effectively keeping the water moving, and thus you’re creating a good environment for pathogens to grow.
