Greetings! Its likely been asked numerous times here but I couldn't find exactly what I was looking for; do the 2 yellow shut off valves in the photo close the supply/return for the rear heater? I dont want to use the rear heat right now and am curious if this will shut it off without looping the lines. Thanks for any help.
