Winterizing Issues

Thanks! I hope that turns out to be the problem.

When I dewinterize, I sanitize with chlorine. Then I follow up after draining that with baking soda. I have ot had a taste issue.

I use 1-2 cups of bleach in a full fresh water tank, run it through all water sources and then rinse. No issues very fast.

I was skeptical the first year I did this even though those who told me "no sweat" had done it for years.  I literally took the pump apart; hmm, no water.  The little filter that you unscrew on the output side of the pump I took off as well, and again, no water to be found.  The pressure obviously clears pump and filter of any water and/or residue.

There is probably enough flex in the plastic line from the water holding tank to the pump that allows for expansion or else gravity must pull it back into the tank.  Our winters get quite cold and I have never had a frozen/burst line issue.  One of the golf courses I maintain has an old Toro hydraulic system for its irrigation controllers.  The 3/8" lines are only taken apart between controllers (31 of them) and then from the controllers to the sprinkler heads (about 400) there is a 1/4" hydraulic line that runs from the controller to the sprinkler head.  Again, no freezing/burst line issues and these are only in the ground about 12-15 inches.  There isn't enough water in the 1/4" to burst the plastic line, even though nothing is done as far as opening the lines to reduce pressure except to allow gravity to reduce inline pressure over the winter months.

Negatory unless the one who put all the icons for us to swipe on this forum took a pic of Whitefish Point, which indeed does look like it.  Did you see any color in the U.P. when you were there or was it too early?
