Waterheater at 130 means no need for filters, showered changes etc?!

May I copy the text of that to a private Australian NTM fb group, without disclosing anything that is identifiable? That is very interesting to hear as we have instantaneous hot water powered by LPG (I'm in New Zealand), and we are not allowed to have it as hot as 130C to prevent scalding. It was suggested to me that NTM would only be in hot water cylinders but if I thought NTM was in all plumbing pipes and wanted to kill all NTM entering our house, we should install a UV filter. I'm sure I read somewhere that UV may in fact mutate NTM's.

Are you saying the UV is good or not good to have?

The problem with UV filtering is that it does not impact any NTM or other bacteria that the light does not contact directly, so anything already living on biofilm in the pipes or hot water reservoir would not be killed.

You may copy the text, but please attribute it to Dr Joe Falkinham, who wrote to Tamara, as he is a recognized expert in the field of NTM and water.

I am sure he is referring to 130F which converts to 55C.
