I have a pool where the pressure rises about 20 psi when the return lines are on the spa. On most pools the pressure rises about 10 psi when the returns are on the spa. The other abnormality on this pool is that the jets in the spa will go in and out, there will be pressure on a jet and then it will completely stop for a few seconds and then the pressure returns. Any ideas on what might be going on here?

Pressure rise is most common with an obstruction. Pressure on the jets coming in and out still could be from an obstruction. I would start by removing the jets and looking for foreign objects.

I don't view the pressure rise when in SPA mode alone an abnormality.
How many jets does the spa have?

What size are the jet orifices?
