Dewinterizing 620

  I would think that's normal,  since it holds 20 gallons plus water lines. 
  
  We use the blow out method, so not concerned about flushing any RV antifreeze out of the lines. I sanitize with spa chlorine granules.  I put a teaspoon in the hose and hook it up, fill the tank normally.  Drive around a bit,  let it sit a few hours and drain and then fill again.

  Thanks DB. I got it sorted things out eventually. Dewinterizing in VT when it’s only 12 degrees the morning I needed to do it was a bit of a challenge. It warmed up to 45 eventually. LOL. Good time of year to head south for a spell!

  I personally don't fill the tank since only the very bottom of the tank has water on it during the winter.  I put in just enough sanitizing fluid to fill the lines and just a bit in the tank.  This for me makes it easier to flush the system of all the sanitizing fluid.  Do this on my boat as well.

  Thanks Rich. I’ll keep that in mind for next season’s dewinterization.
