Q: Is this pump rated for potable water?

This unit is cast iron and should not be used for Domestic Hot Water. It will introduce rust into your system. You need a pump with a bronze or stainless steel body. I used this pump in a domestic hot water circulating system and it turned my hot water brown in 3 days.

Q: Will this unit work with a single valve faucets?

I have both single and double valve faucets and it works well for me. Be aware there has to be a return pipe from the plumbing point furthest from the pump. It is not one of those 'passive' systems that recycle water back down the cold water pipe. I found it to be a real quality product.Mark

Q: Can you add this 3/4" pump to a 1/2" water line using the flange set sold separately and adding 3/4"-->1/2" adapters?

That should work, I just installed on 3/4 pipe. And long as you have the right flange set should be fine. I got the temp gage also and it's good, turn the pump off and on as needed when the pipe warms up and cools off.

Q: Is this pump super quiet? It will replace the one right behind my headboard wall. Got to be whisper quiet.

It is super quiet to start. But after a while it will start to hum as it wears out. I used mine to the water pump that heats my floor. So maybe with the heating over time it does that? Not sure.
