bathroom sink plumbing parts

Every residential plumbing in Toronto has different parts and sections. One of the areas that play an essential role in your home’s systems is the bathroom sink plumbing and its critical components.

But why do you need to have bathroom sink plumbing occasionally? Every home plumbing fixture, for example, bathroom sinks, has several parts that can become blocked, break or leak.

As soon as you feel you need bathroom sink plumbing, contact professional plumbers in Toronto and let them solve the problem.

However, if you want to avoid frequent problems in your bathroom sink plumbing, it is crucial to know the primary parts of the system to choose and buy the most efficient and highest-quality ones.

Primary Parts of Any Bathroom Sink Plumbing System:

  1. Shutoff Valves
  2. Supply Tubes
  3. Drain Tailpiece
  4. P-Trap
  5. Drain Pipes

Now, let’s get into the details about these essential parts of your bathroom sink plumbing system.

1- You Need Good Shutoff Valves for Your Bathroom Sink Plumbing

Shutoff valves are the first essential part of your bathroom sink plumbing. These small valves are usually made from metal or plastic and are located between the water supply pipes and the supply hoses that connect to the tailpieces on the bathroom sink faucet. Most shutoff valves used in bathroom sinks have an oval handle that you can turn to close and open the valve.

One of the best things about shutoff valves in your bathroom sink plumbing is that you can turn off the water supply at the sink without shutting off the water of your whole home.

You can install most of the shutoff valves onto the water pipes without soldering, which benefits most homeowners who want to replace them with a DIY process.

Shutoff Valves in The Bathroom Sink Plumbing are Seen in Pairs:

  • The first valve is used for controlling hot water.
  • The second valve is for controlling the cold water.

2- Use High-Quality Supply Tubes

All of the bathroom sink plumbing systems have supply tubes that need to be high-quality to avoid frequent plumbing issues. High-quality supply tubes are made of:

  • Braided wire mesh
  • White plastic mesh
  • Gray solid plastic
  • Chromed copper

These bathroom plumbing parts are generally connected to the tailpieces and shutoff valves with attached nuts. If you have issues with your supply, it is recommended to hire a professional plumber to fix them.

3- The Drain Tailpiece is Also Crucial for Your Bathroom Sink Plumbing

Drain tailpieces, also known as sink tailpieces, are straight sections of pipes that connect to the bathroom sink drain fitting. If your bathroom sink has a pop-up drain, the lever rod connects to a port on the back of this particular bathroom sink plumbing part.

Usually, a high-quality drain tailpiece is attached to the drain fitting with a slip nut, a threaded ring that you can tighten or loosen by hand, or channel-type pliers. A tapered plastic washer under the slip nut creates a watertight seal for your bathroom sink plumbing system.

Note: Remember to use tailpieces in your bathroom sinks that have slip nut joints since if you ever drop anything into the sink drain, you can easily disassemble the joint and retrieve your item.

4- Every Bathroom Sink Plumbing System Has P-Trap

Your bathroom sink plumbing system has a P-Trap which is made up of two primary parts:

  1. U-Bend
  2. Trap Arm

These two parts of your P-Trap are curved sections that allow your sink to connect to your home’s sewer line. The curved trap is used in the system to provide a safety feature for holding standing water and preventing sewer gasses from rising up and out of your bathroom sink drain.

Every time you run water down the bathroom drains, the old wastewater in the bend is flushed out and replaced with new water. You or your plumber need to assemble the P-Trap parts with slip-nut joints.

5- Be Precise When Choosing Drain Pipes

The last part of your bathroom sink plumbing system is the drain pipe. It is connected to your residential plumbing system from one side, and the other side is connected to the trap arm with another slip nut joint. With slip nut joints, replacing or repairing the pipes will be easier.

Most of the drain pipes used in bathroom sinks are three inches in diameter. However, depending on your fixture, you can choose a smaller or larger one.
