(Disclaimer I own Walgreens stock, I don't regularly buy their distilled water)Tom Magarian wrote: ↑Sun Dec 23, 2018 10:28 amI have been using my Res Med Auto Sense 10 for about 10 months to date.
I have had sticking issues with the water tank for about the last month.
Today no matter how hard I yanked on the tank, I could not remove it. Upon investigating it further, I found that the stainless steel bottom of the tank had cemented itself to the stainless steel heating element.
The problem is caused by mineral deposits in the water, that over time build up and because of the heat, form a cement that causes the tank to stick in the unit.
This was a surprise, because I have always used distilled water from Walgreen's Drug Store. Evidently, the distilled water is not as pure as one might think.
First, I don't know where you evidently found the information that Walgreen's distilled water is not as pure as one might think.
Second, What does "as pure as one might think" mean? This is a humidifier chamber that gets rinsed out with tap water and left to dry. That last step theoretically adds impurities from the tap water to the inside and outside of the humidifier. I'm not suggesting or recommending for people to rinse their tanks with distilled water after cleaning.
Third, Let's go with your theory that Walgreens water is not as pure, Exactly how is the water in your CPAP getting outside of the chamber and depositing minerals on the heating element? Does your tank have a leak?
Fourth, I believe that one solution was proposed in this thread was to wipe the bottom of the tank with a cloth to make sure there is no spilled water or some dirt, sticky stuff from the surface of where the tank sat as you filled it. I also wipe the top of the heating element on the machine every couple of weeks.
