7 Steps to Bathroom Sink Drain Piping

The bathroom sink drain component is the portion of your drain. It transports spent water to your home’s sewage system. The obvious drainage component at the bottom of your sink is the flange. 

A long piece of piping known as the tailpiece is connected to the socket from beneath. The P-trap is a twisted section of pipe located between the tailpiece and the sewage intake.

Fixing a bathroom sink drain assembly necessitates connecting all of these elements in the correct sequence.

What You’ll Need

  • Pliers
  • Putty blade
  • Cleaner for the bathroom
  • Rags
  • Caulk made of silicone
  • Caulking gun
  • Plumber’s tape made of Teflon
  • Preparation of a bathroom sink drain

As we discussed above, you will need to start your steps. Let’s talk about all the steps thoroughly.

Step 1: Wipe Sink Drain Area

Wipe the washroom sink drain’s bottom, paying specific attention to the region around the drainage opening. A fresh surface aids in the adhesion of the drain caulk. To eliminate any mold or mildew, use a bathroom cleanser and clean clothes.

Using a putty knife, scrub away any old caulking or putty. You should install vinyl planks on the bathroom floor.

Step 2: Use the Caulk

Turn the drain flange upside down so that the bottom is facing up. Fill the caulk gun halfway with silicone caulk. Reduce the end at a 45° angle to the 1/8 inch mark. Caulk the bottom of the flange perimeter.

Step 3: Insert the Flange

Place the flange, right side up, into the drain pipe. With one hand, continue to keep this in place. Using your other hand, put the tailpiece into the studs. It must be installed on the bottom of the flange from beneath the sink.

Step 4: Place the Washer

Place the rubber washer and locking nut on the tailpiece’s end. Using pliers, tighten the retaining nut.

Step 5: Remove the Threads

Clean the knots from the tailpiece using steel wool. And the sanitary sewer intake in the wall. Use nonstick plumber’s tape to secure the holes. Create a minimum of one complete circle around the threads. Then use scissors to remove any extra.

Step 6: Insert the P-Trap

Insert the P-trap between the tailpiece and the sewage intake. Fasten the connections with tweezers or your hands (on metal pipes) (PVC).

Step 7: Wait to Dry

Give sufficient time for the sealant in the drainage to dry based on the manufacturer’s instructions. Tap the water. Check the sink for leakage. To keep your bathroom cool, consider installing an exhaust fan

5 Easy Process to Install P-Trap

You can install the P-trap with your washstand mounted to the wall. The U-shape of this pipe acts as a trap. And keeps back enough water to prevent sewage gasses from entering.

Adjusting the P-trap on the pipe leaves the sink drain up and down. You may change it whatever you like. The end of the P-other trap may slide into and out of the wall fitting.

  1. Push the side of the P-short trap into the tailpiece that sticks out of the sink drain. You may line the trapped arm with the wall gap by moving the P-trap up and down. If the trap arm is beneath the wall drain connection. 
  1. If you can’t get the P-trap further up the tailpiece, cut it with a hacksaw. When the tailpiece is attached, the P-trap should reach over the wall drain fitting. Then obtain a longer one.
  1. After separating the P-lower trap part, press the trap arm. As far as the wall drain fitting will allow. Do not add any electrical outlet near the drainage. 
  1. When it is lined with the trap’s top U-shaped component. Remove the trap arm from the wall fitting. You can purchase a longer trap arm. In case the current one entirely exits the wall before it’s connected to the trap.
  1. Use a hacksaw to cut the trap arm if it has been inserted. As far as it’ll go in the wall fitting and has reached beyond the U-shaped trap.

How to Clean Your Bathroom Sink Drain Pipe

If you don’t want to deal with any form of impediment. Then you must clean it every week, otherwise, it will become a big block. After that, it’ll be really difficult to clean, and you’ll need to call a plumber. Now, we will talk about some cleaning ideas.

Method 1: Make Your Own Pipe Cleaning Solution

Simple table salt may be highly helpful for cleansing bathroom drains. Fill your bathroom drain with at least one tablespoon of salt.

Followed by 14 cups of basic white vinegar and allowed to rest for an hour. Then, run hot water down the drain to clear away any debris. Repeat this process for the best outcomes.

Method 2: Keep Pipes Clean

It is essential to maintain good hygiene. After using your table salt cleaning solution to avoid another blockage. Pour a little bleach into the sink now and again to do this. Allow it to sit for a minimum of an hour, then flush it with water.

Method 3: Make Use of Hot Water

Spilling boiled water down your bathroom sink pipes once a week may make a big difference. Hot water can help dissolve and rinse away minor grease deposits in the kitchen sink. Very hot water is beneficial to bathroom drains since it may eliminate extra debris and sludge.

Method 4: Remove Grease Blockages

To clean a grease-clogged kitchen sink, apply liquid dish detergent and a large amount of hot water. Over high heat, prepare a large pot of water to a boil. Pour at least a spoonful of dish liquid down the drain. Pour a modest amount of hot water down the drain at a time.

The fast heating process will evaporate grease deposits. While the detergent will assist in the breakdown of grease and oil. So that it can be flushed away by the boiling hot water. If you have a lot of grease, repeat this method twice or three times more.

Method 5: Use Cold Water

When operating your trash disposal, keep sending cold water down the drain. Cold water keeps oils and grease solid, allowing your disposal to break them apart. Hot water will just loosen and dissolve grease, causing it to cover the garbage disposal.


How far can the sink be from the drain?

The kitchen counter height is most often 36 inches. However, it can range from 30 to 45 inches. Because most kitchen sinks are 8 inches deep. The standard distance between the drain and the floor is 28 in. 

Is it conceivable to share a vent between a toilet, a shower, and a sink? 

Wet venting is most commonly used in connection with toilets and sinks. The sink drain also serves as the toilet vent. It can also be used for different reasons, but only under the conditions outlined below. It’s the simplest and most common scenario.

Is a vent required for every plumbing fixture?

A vent must be linked to every plumbing fixture. A siphon can be induced by the lower pressure of departing water. It flushes the trap if there is no outlet. The tops of stacks must also be evacuated using a stack vent, known as a stink pipe.

Is it possible for the sink and toilet to share a drain?

Put a second vent nearer to the toilet on the toilet drain line. If the sink drain is not within 6 feet of the toilet and cannot be linked to the bathroom drain. The longer the distance between the sink and the toilet, the more likely a clog will form. A different vent pipe will still be required for the sink.
