Jim. Thanks For the replyI,
Either you have good flow or you don't...
If you have good flow out of your pool returns, then the cell or more likely the flow switch is bad.
If you have poor, or weak, flow out of your pool returns, then the most likely cause it that your filter is dirty.
I suppose you could have the cell in backwards... We have seen cases where the cell was originally installed backwards, and then the installer turned the flow switch backwards, to make it work.
As long as the flow light is Red, nothing else will work.
Yes DE filter. Seems last owner Backwashed on may 2020. Here are some pictures. Really going insane hereIt appears you have a DE filter. Have you never backwashed it before? What type of valve do you have on the filter?
the cell is in the right position Jim. That’s the way they installed it. Want any more picture?I,
It sure looks like your cell is in backward to me.. But then I can't see all the plumbing because everything is too close up.
Seems to me that water should flow up through the cell and then go left to your pool returns or right to your spa. ????
Tell me what the valve just above the cell does??
Show me a pic of the cell showing the input and output pipes and where they go..
Do you still have the old cell? If so, remove the cover over the flow switch and show us some pics.. I suspect that the flow switch in your old cell was put in backwards so that your old cell would work.
