Does keeping hot water in a thermos for 8-10 hours breed bacteria?

I was thinking the same! Wouldn’t these NTM bacteria be in the pipes and thus what’s the point of cleaning shower head. Also filtering the whole house, was an option but are the NTM still in all the pipes to come through with the filtered water?

I think it is a matter of bacteria growth in the shower head. Meaning it never has a long enough time between usages to possibly have the water dry out of the shower and therefore bacteria builds and grows and grows???? Yes? No?
For myself I have the hot water tank turned up to about 135-140 and try to drain as much water out of the hand held tubing with it's own shower head before using it again. Not sure that is a perfect solution but it's something. With the cheap materials they use for shower heads today one needs to understand what certain chemicals do and don't do to the shower head itself and for cleaning the shower heads. My understanding is that Vinegar is just for clearing out calcium from the shower head??? Wouldn't one need to use something like bleach if concerned with bacteria build up in the lines or shower head????

First, let's remember that the goal is to minimize exposure to NTM, we will never eliminate it entirely.
My filter canister is below the kitchen floor in the laundry room, in the cold water line, about 3-4 feet from tap itself. The small amount of NTM that could be in the pipes "upstream" of the filter is vastly diluted by the volume of water coming through. If we are gone for a while, we run every tap for 5 minutes, flush every toilet several times to clear the taps per Dr Falkinaham's recommendation.

Dr Falkinham's studies of showers with hot water at 130-135F or above also notes that the amount of NTM exposure from the cold water mixed in is very small.

I cannot speak to the issue of showerhead exposure, but using the above info, I believe that exposure would be small.

Here is my logic - my "rainwater" shower head doesn't produce much mist, the concentration of any NTM is negligible per Dr F, most of the water drains/drips out after use allowing the fixture to dry, so it is an acceptable level of risk to me. If I was a more cautious person, I would possibly soak the head once in a while to eliminate biofilm.

Each of us must choose our own level of risk tolerance. After 5 years with minimal exacerbation and no return of MAC, this is what works in my life.

Thank you, Sue. I knew you would have a sensible response!

That should not be true if the water is staying hot enough in the thermos. The thermos is broken and the water is not boiling temperature hot water then I could happen. Make sure there’s no cracks in your thermos.

I would like to hear about your airway clearance program. Is this for your lungs? I am having problems with my lungs and saw a comment on here about Keytruda so I was looking for that person. But I noticed your comment about the thermos. I don’t think the Bacteria will grow as long as the thermos is not cracked and working properly.

I am a newbie here and just getting traction on all the traditional air clearance protocols, but in my rather dramatic case, I have found that eating warm soups almost exclusively, and large quantities of very warm water keeps my secretions flowing and prevents me from having violent coughing jags like I used to have in the past. Now that I am revving up my aerobic exercise, and my airway clearance breathing exercises, things have been slowly improving. I am very prone to hemoptysis, and one way that I gauge my progress is to not have those bleeding episodes and what I describe is apparently helping. I walk a very fine line in my protocol.

Hope this helps.
