: 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.
===> Personal experience and opinion here, but the drain plug should be left in, but loose so it won't stop any condensate etc.
from dripping out.
Leaving it out invites critters and insects to make nests
inside, even bees & wasps
: 2. Yes, pressure gauges last longer if removed
: in winter.
===> Definitely. There is almost always SOME water left in them as they sit installed. The diaphragms aren't very tough.
