We find that the guys that rinse the lines between jobs and at the end of the day have less corrosion on the fittings and hose reel. However, we know that it is not always possible and when you have several roofs lined up in one day, it is convenient to roll up with the love still in the hose.

If you have a 12 volt or roller pump, it is critical that you rinse EVERY time.
