What Is A Kitchen Sink Drain Assembly?

A kitchen sink drain empties wastewater from the sink. It channels the wastewater into a sewer or disposal area. The entire process happens via gravity.

First, the drain sucks the unwanted liquid from the sink through its opening. Then the waste water goes into the drain line at an increasing speed, where it gets ejected into a sewer or any other disposable place.

The drain piping system consists of a P-trap, which is curved and holds some of the wastewater.

The retained liquid forms a seal. As a result, dangerous and bad smells can’t pass through into your kitchen. The water remains in the curved area because the drain line sits above it.

What Size Sink Drain Do You Need?

The size of your kitchen sink drain should be narrower or the same as that of the sink’s drain hole. For example, if the drain opening is 2 – inches wide, your sink drain size should be 1.75 – inches wide.

If you don’t have the sink manual indicating its drain hole measurements, here is how you determine it;

Step 1: Place a Tape Measure on The Drain Opening

Place the starting point of your tape measure on one side of the drain hole at the center. Then run it across to the opening to the other side.

Step 2: Take the Measurements

Read the measurements and record them down.

Step 3: Measure the Drain’s Shallow Part

After measuring the upper part of the drain hole, measure its lower part to get the size of the tailpipe to use.

With these measurements, you will find the correct drain for your sink.

Things to Consider Before Buying Kitchen Sink Drain Assembly

Drain Position

Your kitchen sink drain position will determine the number of things.

Some drains are offset, while others are centered. Figure out the one you want to install when installing a new kitchen sink or remodeling the current one.

Centered drains are quieter, appear classic, are easy to install, and can fit most plumbing systems. Unfortunately, they can inconvenience you while washing utensils in your kitchen sink and wastes a lot of space beneath the sink.

On the other hand, an offset kitchen sink drain comes with a modern look and makes it easy to wash dishes. It also creates more space beneath your kitchen sink and is easily accessible to disabled or wheelchair users.

But if used in a shallow kitchen sink, the splashing increases. Also, unlike in a centered sink drain, it requires a lot of plumbing adjustments.

If dealing with a busy kitchen and a small sink, an offset drain will be great. Centered kitchen sink drains suit large sinks and projects that require constant renovations.

It’s therefore essential to consider your kitchen sink drain position before buying one.

Size of the Sink Drain Opening

Kitchen sink drains come in different sizes. You must know the exact size of your kitchen sink’s drain hole. The best way to know is by measuring it.

Then go with the measurements to your vendor and pick a sink drain that fits.

A larger or smaller drain than your sink’s drain opening will be useless. It will save you time and money to buy the right size sink drain.

Sink Style

Kitchen sinks come in many styles. Consider a sink drain that fits your kitchen sink design.

Consider the shape and the entire plumbing system. Will it fit and function properly when installed in your kitchen sink’s drain opening?

Some sink drains fit only some specific kitchen sink types. Know your kitchen sink style first, then go for a drain designed for it.

Material

Kitchen sinks are made using various materials. It would be great to pick a sink drain made with a similar material because they will match.

But if you would like to make a statement in your kitchen, you can use a sink drain with different material from that of the sink.

You only need to ensure that the materials complement each other. The same case applies to the finishing. It could be different from that of the sink but ensure that it complements that of the sink.

 Color

As for the color, it’s great if it matches that of the sink. Some colors also blend perfectly. You can choose a sink drain with a color that complements that of your kitchen sink, appliances, and internal décor.

Alternatively, you can go for neutral colors such as which, black, and grey. They blend excellently with all other colors.

Cost

Though most kitchen sink drains are affordable, it’s essential to set a cost limit for yourself. It will help you choose the right sink drain within your budget.

Some kitchen sink drains come as a set of several parts while others consist of only one piece. First, consider what you need for your sink drain. Is it a strainer basket or stopper only, or more?

Some sink drain manufacturers add extra features for better usability. For example, some come with a center knob to help remove the strainer easily for emptying.

You will have to pay more for a sink drain with added capabilities than that without. It does not mean that those without extra characteristics are bad.

If they can sort out your needs and are within your budget, why not buy them? But if have the money, a kitchen sink drain with extra features is preferable.

Cleaning and Maintenance

A kitchen sink drain should be easy to clean and maintain. It’s therefore important to choose a sink drain that does not attract dirt and is hard to clean.

That’s why sink drains made using materials such as stainless steel are preferable. They do not stain, or rust, and clean easily using warm soapy water. Others are washable in your dishwasher.

Durability

A kitchen sink drain made with a robust material such as stainless steel lasts for many years. You will need to know the material used in making a sink drain before buying it. Otherwise, you may go back to the market after a short period.

Kitchen Sink Strainer or Crumb Cup Benefits

Prevents Clogging

Kitchen sink drainers prevent solid waste from going down the drain line and causing a blockage. The strainer allows wastewater and fine particles to pass through its holes into the drainage.

Large particles cannot pass through the holes, trapping them in the crumb cup. When it’s full, you only need to empty the crumb cup or strainer.

Clogged pipes cause inconveniences. It’s also an expensive and tiring exercise. But you can avoid all these with a reliable strainer for your kitchen sink.

Saves Your Small Valuable Items

A kitchen drain strainer traps more than food bits. While washing your dishes or foodstuff, your expensive ring may come out.

If your sink doesn’t have a strainer or crumb cup, it may go down the drain.

You may be lucky when you take out your sink plumbing system and find it. If there’s a lot of waste water going down the drain, it can get push it passed the p-trap to the sewer.

Sink parts and small tools such as nuts can also go down a drain without a strainer. You must put the strainer or cover the drain sink hole when repairing your sink.

Other valuable small items that can go down a sink drain include and are not limited to chains, earrings, and watches.

Restricts Insects Into Your Kitchen via the Sink

Some annoying insects such as spiders and cockroaches may go up your sink drain pipes.

If you don’t have a strainer on your sink’s drain hole, they may get access to your kitchen through the sink.

Fortunately, a reliable drain strainer blocks access to any type of insects or pests.

Your sink’s drain opening directs the size of the drain to use. Kitchen sink drains come in different sizes as follows;

Kitchen Sink Drain Sizes

Kitchen Sink Drain Sizes

If you violate it, you may face obstacles such as clogging, plumbing problems, water contamination, and bad-smelling, dangerous gases entering your kitchen.

b) Drain Pipes Sizes

A kitchen sink drain is not complete without its piping system. It connects to pipes beneath the sink.

These pipes carry waste liquid into the sewer. For the piping system to work well, it must be connected correctly and consist of the right size.

Drain pipes get made with PVC. The modern ones come with a diameter of 1 ½ – inches. The older sinks get connected to pipes with a diameter of 1 ¼ – inches.

  • Gloves

Next, pick the nut and screw it on. Use your hands to tighten it enough. Avoid over-tightening it as it may cause issues with your drain.

As you secure the strainer, excess putty will come out. Wipe it out and proceed to the next step.

Step 4: Put a Washer to the Tailpiece and Connect it to the Strainer Basket

Take the tailpiece and insert a washer. Its angled end should be upwards towards the connection. Then connect it to the strainer basket by pushing it tight from below.

Ensure you screw the nut enough to allow for a wiggle room as you connect the rest of the piping system.

Step 5: Connect the P-Trap

At this point, you have a pipe connecting to the drain or sewer, and the tailpiece you’ve just connected. It’s now time to join the two using a p-trap.

Connect one side of the p-trap with the tailpiece, and the other with the drain pipe on the wall. Tighten the nuts enough not to allow any leakage.

Final Step

After the connection, run your sink’s water to see if there’s any connection problem such as leakage. If any, rectify the issue by redoing the process keenly. If not, you’ve successfully installed your sink drain!
