My pool returns to pool wall jets and to the spa which then waterfalls into the pool.
My assumption is that this valve, controls return to the pool (the pipe at bottom of pic) versus return to the spa (nearly off in this pic)
Right now the flow out of the jets is great and the spa falling into the pool is poor.
I have checked the impeller in the pump and there was no debris.
Do I get flow through pool jets AND flow to spa by virtue of this valve not closing spa completely? The valve is not fully pointing off toward the spa return pipe in this photo)
If so, and I am not getting enough flow to spa when in pool mode, does this valve need to be turned even more to the left to allow more water to the spa?
Should I disassemble this valve and look for debris in the return pipes adjoining it?
This valve has two pegs on the top, both set to 180 degrees. If this sets the actuator to flip 180 depending on pool or spa mode, why doesn't it close spa pipe fully by facing the spa return pipe? When in spa mode this valve will turn fully and block the pool return pipe (again the pipe at bottom of picture)[attachment=0:2ig9dxpy]IMG_12601.jpg[/attachment:2ig9dxpy]
