I just installed a new sillcock faucet to replace an outdoor faucet pipe that burst last winter. I have sweated pipes before and I felt I did a decent job on it. I heated up the bottom of the joint of the sillcock pipe where the threads are located, applied the solder and I was happy with my work. The connections where cleaned and flux was applied before soldering, and I removed the stem from the sillcock faucet fixture before soldering the joint. When I turned on the water I had a leak, but it wasn't from my soldered joint. The leak was coming from the factory connection directly behind the threads of the fixture on the factory joint. I am wondering if this is a factory defect in the sillcock faucet or if I did something incorrectly. I feel like by heating up that joint I possibly compromised the factory joint located directly behind the threads. If anyone can give any advise I would greatly appreciate it.
