I need to replace the diverter and gaskets inside my automatic valve. It controls the flow back to the pool or the spa depending on which side the actuator is blocking.
If I open this valve and remove the diverter to replace it, am I going to have water flowing back through the return jets and gushing up out of this valve?
There are no other valves on either side once the line leaves this valve going into the ground to cut off water supply.
If water would be coming back, would plugging the return jets solve this? If so, what size plugs would I need to get.
Thanks for you help.
