Recently had a navien tankless NPE 240a installed. Also got two navicirc one for each bathroom and set up external recirculation through the cold water line. At the end of a recirculation cycle (can hear the water flow + clicks for the navicircs) one of the navicircs (the one in the master) makes a squealing sound. I tested multiple situations and it seems to be related to the navicirc in the master itself.
