I have a 1" spirovent with a sweat connection on my hydronic heating system that has developed a pin hole size leak at one of the copper connections. There is a bead of water that comes and goes. Typically when I've had a leak on any soldered fitting, I've cut it apart and discarded the fitting and just used a new one. However, at $100 for a new spirovent, I was hoping it may be possible to reuse the old one by sweating it apart, cleaning, re-fluxing, and putting it back together. Any suggestions on cleaning it and re-using it? Or should I just buy a new one to not risk another leak. Thanks for any help with this.
