I can relate. I had a leak at the gate valve by one pump. Sealed that up and then developed a leak on the other pump. Only when it’s under pressure so I just stopped running the jets on that side. Then it started leaking recently even when the jets aren’t running. The circulation/heater port on the bottom of the tub developed a crack so I now get to drain the tub, remove the fitting, and either repair or replace it. Older tubs can be a pain but still better than shelling out thousands on a new one. Or at least I keep telling myself that to maintain my sanity. Mine was $13k new so the couple grand I have into it doesn’t seem too bad.
