My Fix-It class at Emeritus College has been a revelation. My professor Margaret Ross has such a wealth of plumbing, electrical, appliances, gas, and house repairs, that my classmates are having nightmares about not keeping up with a required maintenance calendar. I just learned today that within the dishwasher there is a filter that captures food and it should be cleaned every time you run your dishwasher. Margaret put the fear of God in us about dryers. Not only do you have to remove the lint but there are hidden areas of the dryer that need to be cleaned monthly. She discusses shut off valves. How to keep your water heating from blowing up. What happens with sediment in your toilet. It’s exhausting keeping up with her lectures. She explains how to patch holes, caulking, fix switch plates and hanging pictures. She keeps throwing in these disaster stories where fires and floods occur if you don’t keep maintenance up to date. This knowledge will be helpful when hiring handymen, electricians, plumbers and painters. Margaret handed out a five-page list of verified referrals for a myriad of services. Ms. Ross could pass herself off as a superhero.
