Best Solder For Copper Pipe

Time for some construction work today! If you want to do some DIY construction work on your own, you will need a solder. Now, if you are confused about the solder, then let me explain.

Solder is a mixture of metals that can be used to join pipes and do other repairs. Copper is the most common material used to build water pipes and other household things.

 For bathroom or kitchen water pipes, copper is used. In this article, we will discuss the best solders you can use to work with copper pipes. It won’t be obvious if you are new to construction work, but I can help you.

I have researched the market and have selected the best ones with good ratings. These solders will last you for a long time and will provide you the best performance.

There are some basic things that you need to know before inventing into solders for copper pipe. I have discussed it all.

Go through the article, and by the end, you will know everything about solders for copper pipe.

What is Solder?

Solder is nothing but a mixture of wire that is used to join pipes. You can also use it in different electric works.

The metal alloys can be melted at a specific temperature; later, you can use it to join two pipes.

For copper pipes, people use non-electric solder. In this article, we have only focused on the solder that works on copper pipes.

Different Types of Copper Solder

You can get confused about what to get for copper pipes. There are different types of copper solder available in the market.

You must know the fundamental differences to select the ideal one that will do your job. Not all of the solder can be used in household works. It would be best if you made sure what actual piece you will do, according to your work type, you will choose the solder.

The most common type of copper solder is lead and lead-free. If you are working on pipes for the drinking water, then avoid lead solder. You can use lead solder in drain pipes.

Those are safe to use. The lead-free solder can be used on drinking water pipes. Those are safe and won’t create any bad reactions. The lead-free solders need more heat than the lead solders.

Things you should consider for Copper pipe solder

I am going to explain the necessary things. If you are working on a home project that includes copper pipe repairing, you should keep the following things in mind:

What gas to use

Which gas you will use depends on the material you are working on. First, examine the copper pipe.

What purpose will it have? Is it for drinking water or drainage pipe? For drinking water pipes, the copper melts in comparatively low heat.

For the drainage pipes, you will need more heat. For household work, you can use propane or MAPP gas.

For drinking water pipes, the propane gas is the best one to use. On the other hand, MAPP gas is better for drain pipes. You can use propane gas for drainage pipes too.

What flux to use

Solder flux for copper pipes is an essential tool while you work on copper pipe soldering. Flux makes the joint perfect.

It prevents the pipes from oxidation, and it also makes sure the join has no leaks. If you don’t use flux, then the oxidation can make leaks in the future.

For flux in copper pipe soldering, I would suggest the superior No.75 inorganic acid. It contains Zinc Chloride. You can also use this for iron and hot plates. 

Which torch to use

You can find several good quality torches for soldering copper pipes. Depending on your budget, you will select the one.

If you are low on budget, you can try any torch with a mid-level budget. Those will also perform well and will last a decent amount of time.
