My new setup has three 3-way valves. What is the traditional/or best way to label them to avoid confusion. They aren't in a line, they are at different angles and orientations so no matter how I try to label them it seems confusing. Do you label the pipe the handle tail points to as ON? Or the pipe the "off" tab points to as OFF? What about in between (balancing) positions
For example, on the suction side, the valve looks like this --| The skimmer pipe is to the left, the pump pipe is down and the vac pipe is up. When the skimmer is selected the handle points down. When the vac is selected the handle tail points to the the right where there is no pipe to label.
On the return side, I have two valves in series, and that is where it gets very confusing. How do you do yours?
