Can't win on this issue, it would neccesitate me leaving the spa on thru a Northeast winter while I'm not even present(and the worry of what may happen while I'm not there), though this year quarantine might keep me home.
I've had this tub since 2000 and thru good upkeep it's still working fine but I feel at this age as I work on one trouble spot it might aggravate another spot.
thanks
