I replaced my heater T fittings the other day, however as I was replacing the first one, a small piece of the end on one of the T's broke, and I'm not sure if it went down another pipe. I tipped out as much fluid as I can to "wash it out" If it happened to have gotten in my system, 1- what's the worst that could happen, and 2- what should/could I do to remedy before the worst happens. It's been a couple of days and nothing seems out of the ordinary
