I want a supply line to source from one of two water mains. I was looking at 'y' valves but the ones found all suggest they are 'marine' type (which does or doesn't make a difference). Is there a common Y valve used in home plumbing?
or two regular valves... if this is potable water, you should also probably require one or two backflow prevention valves so one source cannot back-feed to the other.

Only ones I've seen were to divert from one source to two outlets.
I don't know if source selection would be permitted by code with such a valve as you can get backfeeding from one to the other. You'll probably have to put in two valves and code would want a backflow preventer too. We had that system at work for boiler feed from city or well water.
Even if the end use is not potable water, as long as connected to town water it would be needed.

Plus not enough info. Is it potable water or other? What size? If it;s the latter and 2" or so in size, there are 3 way pool valves. And if it's connecting even a potable well system to some other system, eg irrigation, a backflow preventer would be typically required.
It always seems that "potable" ought to mean "can be poted". However I never learned to pote water.
