What exactly do you mean by “return section”?
The water level in the ato is higher than the water level in the return section.
I believe I installed the siphon correctly. It can only go two ways and I went by the picture on the box.
And wouldn’t the fact that it filled so far above the safety sensor imply that neither sensor worked properly?
