Types of faucet Supply lines

Braided Stainless Steel Supply Lines: These are flexible and durable supply lines made of braided stainless steel. They are resistant to corrosion and provide reliable performance.

Copper Supply Lines: Copper supply lines are made of copper tubing and are often used for their durability and resistance to high water pressure. They require soldering or compression fittings for installation.

PVC Supply Lines: PVC (Polyvinyl chloride) supply lines are made of plastic and are popular for their affordability. They are easy to install and resistant to corrosion, but may not be as durable as metal supply lines.

PEX Supply Lines: PEX (Cross-linked Polyethylene) supply lines are flexible and versatile. They are made of a strong, durable plastic material that resists corrosion and is easy to install using compression or push-fit fittings.

Nylon Reinforced Supply Lines: These supply lines are made of reinforced nylon material, providing both flexibility and strength. They are resistant to kinks and provide reliable water flow.

Vinyl Supply Lines: Vinyl supply lines are made of PVC material and are commonly used for light-duty applications. They are affordable and easy to install, but they may not be as durable as other types of supply lines.

Now let’s break down the process into 6 steps:

1: Turn off the Water Supply

Before you begin any plumbing work, always turn off the water supply, so that water pressure will not bother you while you connect the faucet lines. Then find the shut-off valve beneath the sink or near the main water supply line and twist it clockwise to shut off the water flow.

2: Disconnect Existing Supply Lines

After turning off the water supply. You have to disconnect your existing supply lines. You can easily do this Using an adjustable wrench, loosen and disconnect the existing supply lines from the faucet, and shut-off valve. Keep a towel or bucket handy to catch any residual water.

3: Prepare the New Supply Lines

After disconnecting the existing line, Take the two new faucet supply lines and apply Teflon tape on the threaded ends. This will help in establishing a waterproof seal.

4: Connect the Supply Lines

Attach one end of each supply line to the faucet’s hot and cold water inlets. Make sure a snug fit but avoid over-tightening, as it may damage the threads or can be broken.

5: Connect to the Shut-Off Valve

Now let’s Connect the other ends of the supply lines to the corresponding hot and cold water shut-off valves. Once again, make sure the connection is safe but not too tight.

6: Test for Leaks

In the final stage. Turn on the water supply, then look over the connections to check for leakage. If you notice any leakage, you might need to tighten the connections a little at a time in order to get rid of them.

How Tight Should The Connection Be?

When connecting two faucet supply lines together, it’s important to achieve the right level of tightness for the connections. The connections should be snug, ensuring a secure fit, but they should not be overly tight. Over-tightening can lead to damaged threads and potential leaks.

To achieve the appropriate tightness, you can use pliers or an adjustable wrench to tighten the connections. Start by hand-tightening the connections and then use the pliers or wrenches to give them an additional quarter to a half turn. This extra tightening will help create a reliable seal without applying excessive force.

It’s important to note that different materials and fittings may require slightly different levels of tightness. For instance, brass fittings may require a gentler touch compared to plastic fittings. If you’re uncertain, you can consult the manufacturer’s instructions or seek guidance from a professional plumber.

Remember, the goal is to have a secure connection without risking damage or leaks. By finding the right balance of tightness, you can ensure a successful and long-lasting connection between your faucet supply lines.
