so jump r and w? leave them connected or an instant jump?
when i ran the self-test, it said to remove the r and just leave it hanging.
ok, so that pressure switch should have some reading, and go to infinity when it closes, if it closes
i havent yet confirmed the vent tube is clear, but unless some animal crawler through the roof pipe... it should be.... what would be the best way to verify? take the pipe apart?
