The Tools You Need On How To Connect Two Faucet Supply Lines Together

The first tool you need to have is the sink wrench. For your information, this tool is utilized by plumbers for handling faucets since the great-length handle with the mouth-wide will allow you to enter narrow areas.

If you want to connect the faucets yourself from now on, you should have one, and its cost is relatively affordable. 

Next, you will need the fittings by choosing between sink nipple or push fittings. 

The nipple’s sink is a shortened pipe piece fitting that uses your external (male) threads to attach with your internal (female) threads to seal this connection. 

And with the push fittings, just like the names, is the toric joint seal between the body and the pipe. 

Moreover, instead of glues, you can use metal spurs to tighten the connections. Finally, all you need is hand strength to make the attachments sturdy. 

Compression Fittings To Connect Two Faucet Supply Lines Together

One of the ways you can use to connect the lines is using compression fittings. You will see many fittings in various sizes at the store; therefore, measuring the diameter length to buy suitable compression fittings is crucial. 

Its advantage with compression fittings is that they are simple to set up, include manuals, and are not regularly maintained—however, these fittings are not water and heatproof. Still, in general, it is the best option for you. 

There are two types to choose from, the standard and the push fittings. We recommend you use the standard fittings in this situation because there will be no need for adjustments. 

Ways On Measuring Your Water Supply Line

Here’s the step you can follow for measuring your pipeline. 

Firstly, calculate the distance between your water connection to the water shutoff valves. You can add a few inches of length to improve your tool shopping flexibility for comfort. 

Secondly, you ought to shop for the right faucets. There will be additional supply lines with some of you, which you still have to pay for. If the size isn’t too suitable, you will need to purchase extensions. 

Finally, the last step is to attach your faucets to indicate the valve to shut off using the plumber’s tape on your lines’ connections. 

There are two points you should remember. First, the extensions will not influence your water supply; it just extends your line. 

And you shouldn’t let your line of hot water and cold water close together, so it doesn’t take the warmth from the line to another line. 

Water Supply Lines Kinds

As mentioned before, various supply lines are compatible with different compression fittings. Therefore, knowing the types will save you a lot of money. 

We’ve discovered that the supply line will divide into two types: pipe and tube during our research. 

With the tube, you have two options: Nylon and stainless steel braiding. Both of them are flexible, with the stainless steel will be more durable, while the nylon will offer more convenience. 

But, there are some drawbacks relating to both materials. The nylon tube will be easily damaged when used with hot water for a long time. The stainless steel tube will cost more, suiting more in exposed areas. 

You can choose among polymeric coatings, PVC, and flexible copper with the pipe. Only the first two types are the flexible ones.

Both polymeric coatings and flexible copper will be corrosion-resistant, but the polymer-coated will bend easily, and the other one’s installation requires much effort. 

In contrast, the PVC pipe will be more convenient and affordable; however, the durability factor is not assured, so you should only use it with cold water. 

Connect Two Faucet Supply Lines Together – Step by Step

Stage 1: Prepare the tool and protect yourself 

Foremost, switch off your water valve to stop the faucet from pouring. Bring with yourself a bucket. And wear heatproof gloves and goggles to protect your eyes and hand from burning.

Before the next step, you will place the pipe inside the container with a handle after draining and identify the hot and cold lines. 

Stage 2: Examine the connectors

Determine whether you will use the old or new fittings. However, remember to measure the inside diameter to get the correct pipe, even old or new ones. 

When buying the new ones, purchase the fittings at your demanded size and materials to do the job effectively. 

Stage 3: Prepare for the welded areas.

In this step, you should use the emery paper for the pipe’s welded ends. You will need to use the small wire brushes to clean the inside. 

Stage 4: Brush the pipe’s inside and outside.

Like the step’s name, you will need to brush your pipe’s inside and outside using your flux brush. After doing that, you will wrap all the welded areas, avoiding anything dripping on this space. 

Stage 5: Fits your pipe into the fittings

Here, we will divide into two types of supply lines. The flexible ones only require covering threaded ends with plumber’s tape, tightening them, and compression fittings. 

However, the non-flexible ones will need an extra step: bending the pipes to connect them and then using the compression fittings. 

Stage 6: Heat your metal 

Next, do the welding in your desired area. Then use the soldering strips to form the connections between pipes and fittings. Finally, create the surface tension to drag the soldering into the crack. 

Finally, turn on the faucet and check to see any leakages. And you are done!
