Biofilm-associated L. pneumophila concentrations. a L. pneumophila concentrations in recirculating lines as a function of water heater temperature setting. The x-axis reports the temperature setting for the experimental water heater, with the corresponding values for the control and influent plotted for the same time point. The control system remained at 39 °C throughout the experiment. No error bars were calculated due to the biofilm sampling approach used. b L. pneumophila concentrations at the distal taps as a function of flush frequency. Error bars indicate 95 % confidence intervals on biological replicate samples (n = 6). Note that biofilms were subject to repeated sampling of the same area; thus, the numbers represent re-growth between sampling events
