A co-worker was telling me about his first foray into the world of sweated plumbing connections.
He was a installing a new shower valve which involved a threaded connection at the valve and then sweated fittings after that.
He got everything installed and sweated but when he turned the water on, it leaked at one of the threaded fittings. He looked at the situation, realized he couldn't tighten the connection since everything else was soldered in place, so he took the easy way out.
He grabbed the torch and sweated the threaded connection.
Is he looking at problems down the road?
