Have inground pool & spa with Jandy eq. In spa mode, jets are very weak. In pool mode, jets are normal for pushing water over waterfall. Air blower pushes air through 3 of the 7 jets.. Pressure on pool inlets is good. Jet Pressure is normal when filling spa after draining to pool. Status is the same after backwash and filter pressure gauge is 25lb. Any ideas.
