    Soldering Quick Tips

    Brass ball valves just take patience, the brass takes much longer to heat. I always tried to solder the valve on the pressure side of the fitting first, (with the water off) and the handle in the open position, facing downstream. Because the brass takes longer to heat, and any water in the tubing will be drawn to the heat. If the valve is horizontal, I started at the bottom of the fitting, with the flame heating the back of the valve and touching the solder to the joint periodically. when the solder is sucked into the fitting, move the torch and solder slowly around the valve to get a good even bead of solder around the joint. Close the valve and solder the other side. when it cools naturally, turn on water to check for leaks With a vertical valve, keep the valve open, make sur...

    Brass ball valves just take patience, the brass takes much longer to heat. I always tried to solder the valve on the pressure side of the fitting first, (with the water off) and the handle in the open position, facing downstream. Because the brass takes longer to heat, and any water in the tubing will be drawn to the heat. If the valve is horizontal, I started at the bottom of the fitting, with the flame heating the back of the valve and touching the solder to the joint periodically. when the solder is sucked into the fitting, move the torch and solder slowly around the valve to get a good even bead of solder around the joint. Close the valve and solder the other side. when it cools naturally, turn on water to check for leaks With a vertical valve, keep the valve open, make sure the water level is at least twice the valve size from the joint. If you continue to get water rising into the pipe, the bread trick works great, (white bread only, no crust), or you can but a jet sweat ( brand name, but also sold under many other different names) from your local hardware or plumbing supply store. I also had a turkey baster with about 12" of micro drip line attached to the end and sucked the water out with that. solder the pressure side first, the the down stream side. be careful when doing the bottom of the valve, as it's very easy to miss a small spot. Use a small mirror to inspect your work. If you get drips, you are either not moving the solder and torch fast enough, and excess solder is dripping down, or that the valve, or fitting is to hot and expelling the solder. when you have completed each solder joint, wipe the joint with a DRY cotton cloth, quickly, to give the joint a good clean look. As a reminder, when you clean the joints, do not put your fingers on any cleaned or fluxed surfaces, as the oils and dirt from your hands very well could cause the solder not to take,
