Here is the way I understand your setup...
Water flows through your pump and filter and out to the solar diverter in the blue pipe.
At the solar diverter the water is sent directly to the pool returns through the green pipe. And along the way it gets chlorinated by the cell in the pipe.
Or if the SolarTouch controller determines the solar panels can heat the water it moves the valve to send water down the orange pipe to the solar panels.
If I follow the pipes on the wall in this picture it looks like the return water pipe (green) turne the wall.
While the solar feed pipe (orange) goes into the ground.
Are those yellow pipes coming out of the wall suction pipes into the pump?
Now, we follow the pipes around the corner in this picture...
The green pipe contains the chlorinated return water.
The orange pipe contains water to be heated by the solar panels.
I am lost as to where the blue and brown pipes lead.
Or why there is a T in the green pipe,
Or what that manual diverter is for?
Which pipe leads to the pool returns?
The diagram below is a standard solar panel plumbing setup and I used the same colors to correspond to your lines.
The red circled 3-way valve is your solar diverter valve. That either send water straight through to the pool or to the solar panels to be heated.
The unheated or heated solar water connect in a T that feeds the pool returns. The SWG should be placed after the T so that water is chlorinate whether it runs through the solar heater or not.
In summary, you whole setup is janky and I cannot follow the flow. Please explain.
