Answer to Question 1

Make sure the circuit is OFF and properly locked-out and tagged-out. Test the meter on a known voltage source.
Test the circuit that should be de-energized

Answer to Question 2

The pressure relief valve is usually set for 30 psig on a residential or small commercial system and piping is arranged to discharge into an approved drain.

Answer to Question 3

It may not be physically possible to lock out a circuit in a residential setting. However it is advisable to provide some indication that the circuit is off and being worked on so that the power will not be mistakenly turned back on.
