How to Solder Copper Pipe

No one wants a copper pipe to leak in their home. The following is a great way to make sure your pipe joints are leak-free.

Transcript from Video

Hi in this video I’ll be thoroughly explaining how to solder copper pipes, they get a nice leak, free joint if you’re unfamiliar with soldering you’ll be able to solder any diameter pipe after this video with ease and peace of mind. There are 3 steps to solder a copper joint:

  1. Preparation – Preparation is the secret to getting a leak-free joint. If you skip or half do it, it will most probably leak and cause damage to your property. So this step needs to be followed very closely.
  2. Solder – This is the actual soldering process which I’ll get into details in just a moment.
  3. Finalizing – This is finalizing the joint.

With that said, let’s get started all right, so the first thing I want to go through are the tools and materials you’ll be needing to complete the task.


So, tool number one is a torch. You’ll find a good torch at your local hardware, store that should cost you between 20 to 50 Canadian dollars ($15 to $37 US). Yes, there are better models out there for commercial plumbers, but if you’re a Do-It-Yourself doing minor work, these will do just fine to be able to use your new torch you’ll be needing some fuel.


There are two varieties of fuels for you to choose from. You’ve got your ordinary propane gas, which you can either find in your camping aisle, which should look like this or in the plumbing section, at the store or map gas, which should look like this. The difference between both of these is that map gas burns hotter than propane, which in turn heats up your joint quicker.


So, it’s up to you to choose which one you want to use next up is a lighter for your torch. If your torch doesn’t have one builtin like this, you can either use a dedicated igniter, which can be somewhat costly or use a $1 Bic lighter like I do. Your pipe and fitting will need to be cleaned from any surface corrosion or dirt. That could compromise the joint while soldering to do this you’ll be needing some sandpaper or emery cloth for the pipe and wire brushes for the fitting something else.


You’ll need is some soldering flux or paste. The primary purpose of flux is to prevent oxidation of the base and filler material without it, soldering is literally impossible. Here’s what trying to solder with and without flux looks like, and the last thing you’ll be needing is solder.

There are many filler materials that can be used for soldering, copper, but the most two common ones are leadsolder and leadfree solder lead free solder, which is also known as 95/5, is what’s used for potable water line when doing copper drains leadsolder, which is also known as 50/50 can be used, seeing it won’t come in contact with anyone.

Cleaning Joint

So, as I mentioned earlier, the video preparation is key to having a good leakfree joint. The first step to accomplish this is to clean both parts that will be joined together to clean the pipe.

Take. Your sandpaper and sand, the portion that will penetrate the fitting till it resembles this, as you can see, there’s no more surface spottings and that’s exactly what we’re looking for.

Next is the fitting you want to use a dedicated size brush where you’re fitting to get it clean. They most often arrive clean from the manufacturer, but it’s important to get the surface roughed up a bit just so the solder can adhere better if you’re, a commercial plumber and are cleaning a large amount of fittings in a day, a cool trick that I learned Is to cut off the tip of these and use them in a drill as such, making the process much quicker and less tiring, with both of your surfaces now prepped, let’s assemble them, but before you’ll need to apply some flux. Applying flux is pretty self explanatory. All that’s needed is enough of it to cover both surfaces.

That touch just like this. With your flux now applied it’s time for the actual soldering process, which is step 2 now. The goal here is to heat the portion. You want your filler material to be pulled into there’s a scientific term for this, and it’s called capillary action.

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces, meaning it will flow upwards, which is pretty cool. It’s imperative to start heating, your joint at the bottom first, for two reasons: reason: one being is: if you start heating the top first, your solder will want to flow down due to gravity, but won’t have anywhere to go since the bottom of the joint is too Cool to melt the solder so always start from the bottom and work your way up and reason. Two is, as you heat the bottom, the heat rises and heats up the top of your joint, as opposed to starting on top, which takes longer for the heat to go down so keep on heating it up while testing your solder every now and then to see.

If it gets sucked in eventually, your joint will be hot enough to accept your solder, so go ahead and run a nice bead all around the joint to ensure full coverage. A good tip here is always inspect your joint after soldering. It it’ll speak for itself, meaning that if you haven’t correctly heated the joint, you should get something that looks like this. If this happens, all you have to do is reapply a bit of flux, heat up the joint and solder the affected area as a final step.

When you’re sure that your joint is soldered correctly wait a couple of minutes for it to cool down, some plumbers will use flux to clean up the joint while it’s still very hot, but doing this could cause a big drop in temperature in very small amount of Time and can fracture the joint causing a leak once your solder solidifies use a rag to wipe off any excess flux that could potentially eat up your pipe in the long run and you’re done.

If you’re having problems with a copper pipe, one of the best ways to solve the problem is by soldering it. To do this, you can use a propane torch to heat the copper pipe up and then solder it again. This will leave you with a shiny copper pipe. To prevent sweating, be sure to wear insulated work gloves while handling copper pipe.

How can you tell if your mainline is clogged?

With a waterhose, check for blockages in main lines. Any bubbles coming from the faucet indicate that there is a blockage in the mainline.

A flashlight can be used to shine light inside the pipe, even if you don’t possess a water hose. If you see any movement inside the pipe then it is time for a plumber to come.


Can Coca-Cola unclog a toilet?

Yes. Coke has published the entire article entitled “How to Unclog a Toilet with Coca Cola”. You only need to remember that you can only use Coca-Cola Classic since Diet Coke doesn’t contain phosphoric acid.

  • Water damage is the leading cause of home insurance claims, accounting for around 40 percent. (
  • My material cost is between 25-30 percent of the cost of the job.” (
  • Your tank should be pumped if the bottom of the scum layer is within six inches of the bottom of the outlet, if the top of the sludge layer is within 12 inches of the outlet, or if more than 25% of the liquid depth is sludge and scum. (
  • For about 90 percent of clogged toilets, you only need one special tool — a toilet plunger. (

How do I make sure my home plumbing works efficiently?

Water leaks, clogged toilets and drains, as well as broken pipes are the most common problems homeowners face with their home plumbing system. These problems are most often caused by a lack of clear instructions on how to properly maintain your home’s plumbing system. This article will help you keep your home’s plumbing system running smoothly. This article contains some helpful plumbing tips and tricks that you need to know before you attempt to fix them yourself.

If you plan to remove one of your plumbing fixtures (such as a sink or toilet), you may want to think about replacing it with something longer-lasting. You could end up spending a lot of money to replace something you don’t need.

You can avoid having to replace a fixture that hasn’t been around for a while by checking the materials used in its construction. Ceramic sinks can last longer than plastic ones. If your sink starts to crack, you should consider replacing it. Ceramic sinks can be found at large retailers such as Home Depot.

As we mentioned, grease shouldn’t be poured down the drain. Instead, use a garbage disposal to grind up food scraps. A problem with disposers is that they don’t always completely break down fats, which means grease can build up around them and eventually cause a blockage. If this happens, it will be impossible to turn off the disposal and you will have to call the plumber to repair it.

When you’ve got a leak in your bathroom, it’s often a good idea to first look for signs of mold growth inside the walls. Mold can create tiny cracks which allow moisture to seep in through walls. Sealing any cracks or holes you find is the best way to stop mold growth. Unfortunately, this can take quite some time, especially if you live in a house built a while ago. You can speed things up by purchasing a mold remover. This dissolves the mold and prevents it coming back.

It’s not safe to pour anything down the kitchen sink drain. Some products, like soap, toothpaste, shampoo, and cooking oils, can cause damage to your pipes. Even though you can flush these items down the toilet, it’s a good idea not to.

Toilet bowls can’t keep liquids indefinitely. If you notice that yours is looking dirty, it may be because it is holding on to too many water. To remedy this, you will need to remove the tank’s bowl. Next, turn the water off until it stops gushing. Once you’re done, you can rinse the bowl with clean water and then refill it with more.

Next, turn off the boiler’s hot side. Then slowly open the cold valve. Let 1/4 cup cold water flow for about 30 seconds. After 5 minutes, stop the flow entirely. Wait 10 more minutes and repeat the process. You will repeat this cycle until the temperature stabilizes.

There are many options to unclog a drain. One option is to use a plunger. Push the plunger against any obstruction in the drain. This may work when there’s little debris in the drain, but plunging can also damage pipes. Plunging is not recommended if the drain is blocked with large amounts of debris.

You can flush your toilet with plain water if it isn’t working or feels stuck. Although most toilets come preloaded with the proper amount of cleaning solution, sometimes less is more. Flush twice, wait 30 seconds, and flush again. If the problem is resolved, you have the right cleaner for your model. If not, you can add more cleaner to the solution before you try again.

If your toilet isn’t working correctly, check the float level. It is important that water levels are at least halfway filled. Low floats can cause the water to not flow all the way down the tube. If the float is too high, the water can overflow the tank and flood everything below it. You should check the fill line (a yellow mark on the tank) and make sure it is parallel with the rim.
