Yep, that will wake you up quick when the CPAP stops working. I had that happen one night when our power went out. That is a shocking way to find out when you can't get any air. Glad you are getting it all fixed. We have been dealing with major plumbing issues with the lines under the cement floor. Three days later we still have to have another company come and line the old galvanized pipe that is rotting away. What a major job and expense by the time we are done.
