I am looking at my main diverter valve (another name?) to see if it is not turning fully to allow water to get where it needs to go.
This question is being generated because, when in pool mode, the water flow is supposed to be going to the spa and cascading into the pool, but in the last 6 months very little flow out of the spa is noted (sheets down wall instead of previous waterfall)
My main Hayward Pool pump operates with no abnormal noise and I appear to have good water flow into the skimmer and out of the wall jets
I do not know if my solar heating (separate pump) and booster pump for cleaner influences water flow/direction/pressure.
Could something have changed in the swivel of this valve?
Here is the position it is in when operating spa - the side of the valve facing us says OFF (right over the pipe coming toward us).
Realize that with a busy life I have forgot the water flow of my pipes 100 times despite knowing it the month before!
