Water Softener Installed
The water at our house has too much calcium so I just bought a water softener that is on sale at Sears. I had some help on my last plumbing project - moving the laundry room to the main living level of the house. Having watched that person sweat copper pipes, I thought I'd try doing so for this project. I bought everything I'd need including a propane torch, plumbing solder & flux, and all the pipe, adapters and valves. I designed a 3-way valve so that I could easily engage or bypass the water softener. At each connection point, I sanded the outside points, and steel-brushed the inside points, and dry-fitted things for sizing. Then, I fluxed and soldered together what I could before cutting into the main water supply. I turned off the water, and cut the main supply where I planned to attach all of this, and noticed that although the water was off, it was still sitting in the pipe below my cut. How was I going to get that out of the pipe, I wondered? I tried using flexible tubing to syphon out the excess water and then finishing the job. But from that point forward, the solder just wouldn't take. What was the problem?
I called a plumber for help finishing the job, and learned what I'd done wrong. Since we're on a well, he had me turn the well-pump power off, drained the holding tank, and then opened the shutoff valve. He explained that any water or steam in the pipes prevents proper soldering - the water cools the heat necessary to solder, and steam pressure blows out the solder. Watching his technique, he soldered much faster that I had, heating the fixtures (not the pipes), and touching the solder to the opposite side of the torch, allowing it to run quickly into the seams. Then, he painted the job with a little more flux, wiping it clean with a rag. It all works well now, and I got a $200 plumbing lesson... for about the same cost of a 2-hour flight lesson.
