Just wondering if you got my post about the pinkish/ peachy residue that I got on my shower head, sinks and toilets. I posted last night. I have lived in this condo for 19 years and contracted Mac about a year after I changed the water heater. I live in Cranston, RI. Once the water heater was changed the pink residue disappeared. I stay on the lookout for it as the plumber told me it was from the metals in the water that sink to the bottom of the water heater creating sludge. That means the water heater is ready to burst. I also have sinus problems but never got them checked. Too many other bigger issues to deal with. Mac, bronchiectasis, gerd, atrial fibrillation and fibromyalgia. All diagnosed.
