Clean and flux the surfaces of the pieces, heat until solder melts and is drawn into the joint, let cool. Remove the heat and immediately touch the tip of the solder to the connection. The brighter blue portion of the flame that comes to a point within the flame is the hottest part of the flame. Push the SharkBite onto the pipe and make sure it's flush with the mark. Once the solder is molten, place the tip of the desoldering pump against the solder that you want to remove. When re-soldering an old joint be fully prepared to cut that joint out and replace it dr. Copper and PEX piping are the preferred alternatives and can be used in place of the leaking pipe by using sharkbite . You have the choice to use a wide range of tools mentioned above. Soldering copper pipe together can be frustrating for some people. If it melts on contact, you can be sure it's sufficiently hot. The tried and true method for connecting copper pipes has always been soldering, but it's a difficult skill to master. If you are adapting to the copper make sure you ream out the inside of the pipe so it's smooth and free from lips/copper pieces that could impede water flow. You must heat the copper tubing and fitting for about ten or fifteen seconds before touching the solder wire to the hot copper.

In addition to eliminating the need for soldering, you don't need any glue either. If it sticks, twist it about a quarter of the pipe to work it free from the solder. 01-04-2009, 12:28 PM. Although this might seem a bit daunting, it is possible by following a few simple steps. Any damage in the copper pipe or making the pipe thinner will jeopardize its structure. As solder is attracted to heat, the copper coils suck up the solder from the metal surface. Examine inside all cut copper pipes to ensure that the burr (a ridge of copper shards caused by the saw where the cut was made) has . The SharkBite works with copper pipes but also plastic models like CPVC and PEX. You will even get a connection to it. The solder will melt at approximately 180°C, so it gets pretty hot! Step 8: Remove the 15mm copper pipe's olive puller. Richard Trethewey shows another effective way to connect these pipes without pulling out the blow torch. Advertisement.

Apply flux around the hole. 3. The recipe for soldering success calls for two parts prep work and one part science. Dipping the fitting and pipe into water will rapidly cool it off enough for you to (cautiously) be able to touch again. The best method of re-soldering a copper pipe join without removing it is to simply drain the water, then use some sandpaper, plumbers tape, and a soldering torch. You want to line the blade up to the mark you've made on the copper pipe after measuring it. Heat the pipe and melt the solder.

If you are one of the solder challenged and ever wondered if there was a way to connect copper pipe together without solder, then you need to look at a new type of plumbing devices that . Heat the fitting until you see the silver-colored solder begin to melt. Flame soldering (also known as torch soldering) is a type of soldering that can be done by hand or by machine. Pinhole leaks are commonplace and the only way to properly fix them is by removing the leaking section of pipe and replacing it, with either copper, PEX, or PVC pipe. If the metal has reached the proper temperature, the solder will melt and be drawn up into the joint by capillary action. How do you fix a leaking copper pipe without soldering? Step 1: Position Copper Pipe. Heat the fitting for another 30 seconds so it stays hot after you move the torch away. If it melts, the temperature has gone to its optimal point. Some soldering wicks come with flux which makes it easier to remove the solder from the surface. Touch the solder to the pipe.

Might be a problem for a novice because of the location. All three parts of the flame should be blue; if the flame is orange, turn gas down. Use emery cloth or steel wool to clean the outside of the pipe. This is a modal window. When the copper is hot enough, it will actually draw . Take a wet rag and wrap it around the copper female adapter. Step 8: Remove Excess Solder. Use a torch played at the top of the pvc male adapter that is broke off, just to get it soft. In case it sticks, free it from the solder by twisting a quarter of the pipe. Blow out the pipe to make sure all copper bits are removed. Heat the fitting until you see the silver-colored solder begin to melt. I even saw my HVAC guy, after heating 1 1/4" to the boiler, add solder as if he were melting wax in a flame.
