The sight glass from my current system was wasting away in the ends. I've been living in my house for the past 4 years and was paying an expert to do the annual maintenance of my boiler, close to $400 USD. After doing my research, I felt that I could maintenance a good portion of the boiler myself. (I am not a licensed plumber). I was able to replace the sight glass and clean everything out as well. I did purchase a glass cutter from the bigger box stores to cut the sight glass to size. Highly recommend for those with Williamson boiler or similar to get this repair kit.
