Water in the tube after adding water tthe humidifier reservoir beyond a certain point

[drago7579]

I have a Resmed AirSense11. When I add water beyond the first line (approx halfway to the max), I will notice water entering the tube. Have any of you run into this issue? Wonder if this a flaw with my specific machine or a common issue or something to do with my settings? My humidity level is set to 5.  The problem with just adding water to that first line is I'll wake up with my sinuses congested after the water runs out.

I've only had that issue due to rain-out, but never seen any water actually go through and into the tub from the resovoir.

It should not happen. It might be condensation. You can use a heated hose.

I think I will try raising the hose temperature  to 84 (from 80) and lower the humidity slightly (from 5 to 4).

This device requires so much experimentation. A year and a half and I still don't have it right.

Lots of folks here who struggle with condensation use a hose lifter.  Amazon sells lots of different ones.  Here's an example of a cheap one that works well:

Yes, a hose holder works wonders. Once you have one, you'll never regret it. No more rain-out and it makes hose management much better.

I do have a hose holder. I went ahead and filled the reservoir to the max and hooked it up. There was a little water that ended up in the hose when I fired it up but it didn't go up. I let it run for a minute and it was gone. Interesting. Maybe I was overreacting after first seeing the water enter the hose when firing it up, assuming that it would make its way through the tube. There have been instances where there would be rainout but that might have been due to the humidity setting.

I'll give it another try tonight and report back.

I have an AirSense 10 and although I do use the humidity option, I never choose to heat the hose. I like the moisture, but not when it's warm. 

I've never had any kind of rain out to deal with. I tried a night or two w/o using the water chamber and it sucked. Thought maybe the 2nd night might be a little better than the 1st, but it wasn't. I went back to a full water chamber and never looked back.

Doesn't the 11 series humidifier tub have that built-in X pipe on the lid like the 10 series? If so, water in the tub should not go beyond the tub itself unless tilted over.
