However, it doesn't seem to be working properly and I'm not sure why. I invariably wake up with an extremely parched mouth, and the water level in the tank barely drops, if at all.
I have examined the water tank compartment of my machine and it doesn't seem to be faulty, as far as I can tell, although there is a little L-shaped bit of plastic that links the whole in the side of the actual blower with a hole in the back to tank that did fall out. I have put it back position as far as I know but am wondering if this could be the issue.
The clinic tells me that it could be something to do with the ambient temperature in the room and have advised me to insulate the hose. I am sceptical but will go along with the advice just in case they are right. Any other suggestions?
