The water heater in the guest room, equipped with a tempering valve is located on the other side of the wall of the guest bathroom, in the garage, and is only turned on when there are guests in residence. The main water heater, without the tempering valve, is in the laundry with the kitchen on the other side of the wall and the bathroom on the other side of the laundry, so no long runs of pipe there either.
Of course there is always the chance that the Feds are monitoring this forum and have taken note that I haven't got a tempering valve and there is a squad from the Noncompliant Plumbing Division on it's way as we speak. Keep your head down Hans................oh no.... I've let on the ID of our plumber...

50c is the temp where you don't kill legonaires and other bacteria. Hence why its set higher to kill off any other contaminants too.

What water conditions are best for growth of the organism?

A.Warm, stagnant water provides ideal conditions for growth. At temperatures between 20°C-50°C(68°-122°F)the organism can multiply. Temperatures of 32°C-40°C (90°-105°F) are ideal for growth. Rust (iron), scale, and the presence of othermicroorganismscan also promote the growth of LDB.
