Hello,
There is no direct way to do this, but if you're creative, you may find a way. For example, you could set up your controls such that when Pump A turns on, it also changes the status of a 'dummy' pipe to closed. The condition to turn it on would check if the status of the pipe is open. If it's closed, then turn pump B on and switch the pipe status to open. =)
