I called Delta to figure out which version of their valve body to get. They said "with stops" is better than "without stops" because you can shut off the water right at the valve. That's all they had to say. Nothing in their product brochures or literature tells you what this stuff really means, and I've looked at a lot of it.
Is there any benefit to being able to do that?
I could see one advantage in that I could hook everything up, test it out, and then turn the water back off at the valve while leaving the rest of the house water on while I finish up things. Or am I seeing the purpose of this wrong?
