If you have an extra station on the timer, run up some time on it and manual start it. The pump will kick on and none of the systems will run - make sure you have a hose open on the pump going to the pool. When done, Zero out the time on that station on the controller - must be done before setting it back to automatic because the timer will still tell the pump to come on if there is time on it. Blow up pipe or burn up pump.
