The pipes would need heat to build pressure, no? Where does that come from?

What ifffff the home tips over with all the extra wieght of the valves.
Just kidding , Anyway what makes it a open system if there are no open valves? Boilers often have 2 valves installed.

Larry put ten valves in, if you are going with the more valves is better theory.

I am sure all the water leaking costs waaaaay more than an extra valve and labor.

Two valves seems redundant to me and not as safe as one valve.

I am starting to think some of the posters are Valve Salsemen.

How is one valve safer?

When all the faucets are closed in the house it's the same.

No problem my friend. The snow is getting a little deep in Michigan, too.

You gotta admit the ten valve things was good though.

I have never seen a water heater installation manual recomending two valves. Dosen't mean it is wrong though. Probably the plumber needed some extra money for the weekend or something.

Permitted by some unadopted plumbing code. I guessed that. Thanx Larry.

Further along was interesting, not allowed in Chi Town, that would be right also, they have to be different about everything.

Most international plumbing code states only a valve on the cold water is required in order to service the water heater. However two valves are more convenient for servicing. There is absolutly nothing wrong with it. Especially when the tank is in a bad spot i.e the aforementioned attic. The The tank would not be a closed system because of the TPR valve. If it is bad then that is a whole different problem. I hope that helps.

Thank you. But I am as confused as when I started.

One is needed, two is OK
