I hope someone here can help me. When "winterizing" a sand filter, should
the handle be left in the "backwash" or "winterize" position? I would have
thought "winterize" was the obvious answer but my pool guy left it on
backwash. Also, should the pressure guage be taken off?

1. Where there is any risk of freezing, remove the
drain plug from the bottom of the filter to empty it
(and leave it off all winter.) The position of the
control handle is irrelevant.
2. Yes, pressure gauges last longer if removed
in winter.
