How Can You Figure Out What the Problem Is?

How Can You Figure Out What the Problem Is?

Before directly jumping into the topic and explaining the basic steps of fixing a Leaky sink drain pipe, it is essential to clarify if it is a leakage issue or some other issue.

The first issue is locating the problem and knowing where it’s arising. It would help if you had to turn off the main water supply and examine the pipe properly. You can find it by inspecting the water dripping out of the pipe; the pipes have been clogged because of excessive drainage, the P trap nuts have become loose or holes in the pipe, etc. So, make sure you examine it properly.

Once you have located the problem, it’s time to act on it!

4 Easy Ways to Seal A Sink Drain Pipe

4 Easy Ways to Seal A Sink Drain Pipe

There are several ways by which you can quickly fix a Leaky pipe. In this article, we are going to discuss multiple methods, but to save you time, here is the list of all the ways that we are going to discuss in detail:

  • Patching leaks temporarily
  • Fixing Leaky pipe connections
  • Replacing the P-traps
  • Replacing the sink strainer

Before discussing the methods and details, you must remember certain things. For example, ensure the sink (having a leaky pipe) will only be in use for a short time. Furthermore, before starting the work, you have to close the main water supply so that water flow wouldn’t be an issue. Each method has multiple options so that you can use anyone based on compatibility.

1. Patching Leaks Temporarily

The options mentioned below or discussed in this section are temporary options that can be used when you don’t have much time to fix the leaky connections/pipes permanently. So make sure that you are following the procedures carefully! As a note, we want to remind you that after certain months you can again face the issue of a leaky pipe.

With the Help of Epoxy Putty

Epoxy putty is one of the most commonly used options by most house owners to fix a leaky pipe. You can easily buy it from a nearby hardware shop or order it online. This option is very budget-friendly and does not require professional help. The best part of using this option is that epoxy can stick to any type of pipe, so you don’t have to worry about the material of your pipe.

The epoxy putty packaging has two components: a hardener and a base. Knead the components and mix until and unless they get solidified to around 1.3cm thick. Apply this mixture in the section from where the leakage is taking place. Cover the area adequately, and re-apply it after a specific time. Leave this mixture for some time until it gets dried.

To check whether this worked, open the tap water for 1 minute. If you see, there is no leakage; your job is done. Most of the time, the epoxy putty does not show leakage signs in the first 2 to 3 days. After some time, you can notice the deposition of moisture or water in the epoxy putty, which means you have made a few errors while performing the task. Remove the dried epoxy putty nearby the pipe, as it is useless. Now, repeat the procedure without committing any mistakes.

With the Help of Silicon Tape

Silicon tape is another temporary solution that can be used in place of epoxy putty. It can be easily found in hardware stores, or you can order online. If the leak is nearby the joints of the pipe, then this is the best temporary solution for fixing the pipe.

Furthermore, if you live in an area with very high water pressure, we recommend you use any other option. This option is very suitable for a location where the water pressure is low because the Silicon tape can last for a few months in such a situation. The high water pressure will not allow the Silicon tape to stick to the pipe for long.

Another crucial thing about this option is that the Silicon tape does not tightly attach or stick to the pie, so you must repeatedly overlap it to enhance efficiency. Make sure that you make a tight seal by rotating it properly. The process of silicon tape is very similar to the regular tape we use in our stationery. So you don’t require professional help or a DIY video to do so.

Note: When you try this option, ensure your pipe is clean and dry. The wet pipe will not allow the Silicon tape to stay in place for a very long time, so give the Silicon tape a proper time to make a tight Junction with the pipe.

Using a Pipe Clap

Most of you may not hear of a pipe clamp, but it is a type of flat rubber piece known as a gasket. It also has a metal fastener attached to the pipe and helps you to secure the leak temporarily. This can be easily found in the nearby hardware Store, or you can order it online but make sure that you already know the dimensions of your pipe.

Your pipe size and the pipe clamp size should be similar to form a tight seal, thus preventing leakage. They come in different sizes so that you can search for an appropriate-sized clamp. Moreover, we recommend you avoid the clamp if the leakage is nearby a corner or joint of the pipe because this clamp requires a proper place to sit or fix.

So if the leakage is near a corner or a joint, the pipe clamp will not be appropriately adjusted, resulting in the leakage again. After you have located the problem and invested in a suitable pipe clamp, we recommend you use an adjustable wrench to tighten the clamp.

NOTE: the adjustable range is a widespread plumbing tool and will help you to tighten the loosed nut of your plumbing system.

2. Fixing Leaky Pipe Connections

There are several options for fixing Leaky pipe connections. This section will discuss the most common and simplest option that can help you without investing much time in fixing a leaky pipe.

By Tightening the Slip Nuts

Several types of nets are all over your house’s plumbing system. Whenever any leaking issue occurs, you should check if it is nearby the nut or pipe. Most of the time, the nut can lose, too, resulting in leakage. So we recommend you locate the problem, especially where the vertical pipes are connected to the drainage system of your house.

Now rotate the nut enough in a counter-clockwise direction to tighten it correctly. If you don’t want to use your hands or notice that you cannot turn the nut with your hands, so use the adjustable wrench. This will help you to tighten the nut, thus preventing leakage. To check if this works or not, turn on the water supply. If you see no leakage means the job is done. But if there is still leakage, tighten the nuts again. To enhance this process, ensure there is no Leaky water nearby the pipe, so wait until it gets dried properly.

Replacing the Rubber Gaskets

Every component or object in your house requires replacement when it gets old, RIGHT? The same happens with the plumbing system as well. A small rubber piece, a gasket, is fitted into your pipe to make a strong connection. It is sometimes also known as a water-tight seal because it does not allow the water to leak. But once it’s getting old or cracked, it can leak, so replacing them becomes vital.

Whenever you buy the gasket, make sure you know the size, or for your help, you can take the old rubber with you to ask the shopkeeper to give you an appropriate-sized new gasket. Don’t worry. You don’t need professional help to perform this; you just have to loosen the nut and place the gasket. Ensure that the gasket’s narrow end is towards the end of the pipe to make a firm, water-tight seal.

Wrapping the Teflon tape Around the Metal Pipes

This is one of the most commonly used options, even by plumbers. This kind of tape is also known as plumber or Teflon tape. They’re responsible for making a water-tight seal so that the water does not get leaked from the pipe. This works best if you have metal drain pipes at your house. Firstly unscrew the nuts, and you will notice some threadings around the metal pipes. Now use the plumber’s tape around this threading to overlap them clockwise and make a tight seal. Once you are done, cut the tape and screw the drain back together.

Note: Do not use Teflon or plumber tape in the plastic or PVC pipes because if you overtighten, the tape will damage the pipes, or the pipe can break. So avoid using Teflon tape in a plastic pipe.

3. Replacing the P-Traps

The p-trap is commonly found under the sink and can be easily visualized by the human eye. You will notice a P or U shape attachment under your sink, known as a P trap. This part of the drainage system is critical. To replace the P-trap, follow these steps:

Step 1: Collect all the materials like a new P-trap, a bucket, a cloth, an adjustable wrench, a flashlight, etc. You don’t require a flashlight if you can quickly see every part of the P trap under the sink.

Step 2: Place the bucket under the leakage area. If you are working in the kitchen sink, then it will have several contaminants blocked at this part. The P-trap is one of the most crucial components of your plumbing system, as it is directly present under the sink. Every water and food particle from the sink moves and deposits in this area.

Step 3: Unscrew the nut near the P trap and adequately collect all the residual water and contaminants in the bucket without creating a mess. Use a cloth to clean the lot, as it will smell.

Step 4: Clean the nearby area of the pipe before installing the new P trap.

Step 5: Now,  place the new P- Trap in the place. Make sure you do it correctly. Attach the right sides of the P-trap to the pipe. Once you have fitted the P trap now, it’s time to screw the slip nuts back again.

Step 6: Once you have completed the task, perform a run test by initiating the water supply for some time. If you see no leakage means the task is done. But if there is leakage, we will recommend you tighten the nut again.

If you use this option, you must keep certain things in mind. For example, the P trap comes with various options that entirely depend on the material of your pipe. For example, the metal Pipe and plastic pipes are different, so the p-trap also varies. Apart from this, to enhance the efficiency of the P-trap, we recommend you perform maintenance every three months by cleaning the P- Trap with a flexible wire. It can be easily found in hardware stores, or you can order it online.

4. Replacing the Sink Strainer

A sink strainer is one of the most budget-friendly options, which not only helps you solve the issue of sealing a sink drain, but it prevents you from most of the problems associated with your plumbing system. A sink strainer can be easily found in nearby stores, and you can order it online.

A sink strainer’s primary purpose is to prevent the food from getting into your pipes, which causes leakage and cracking. It will not allow the food materials to enter the pipe and create specific issues directly.

If you want to avoid going through the complex process of losing the nut and going under the sink, you can buy a simple strainer and keep it in the sink area. Whenever you use the sink to wash the utensils, place this additional sink trainer; this will work as a double protection.

Apart from this, you can permanently fix a new sink strainer if there is any problem with your previous one. We have listed the steps below:

Step 1: Disconnect the drainage pipe by going under the sink and losing the slip nut. Rotate the nuts in a counter-clockwise direction.

Step 2:  Remove the sink strainer by grabbing it properly and pulling it out from the top. Kindly note that few strainers have screws, so ensure you unscrew them properly.

Step 3: Make sure your new strainer size must match the old one. Before installing the new one,  clean the drainage hole with a tissue or a cloth.

Step 4: Apply the plumbers putty around the hole to make a water-tight seal, and place your strainer. Create enough pressure so that the sides of the strainer of the things can attach to the putty and make a vital Junction. Now place the new strainer in the hole, and ensure you are fixing it properly.

Step 5: It’s time to attach the pipe again with the drainage, so do it properly and tighten the nut. Ensure you do not overtighten it because it can result in other issues afterward.

Step 6: After some time, perform a run test once the putty is dried. If there is no leakage, you have completed the task properly.

Above are the four methods that can be used to fix or seal a sink drain pipe. As an ending note, we recommend periodically maintaining the sink and pipe to enhance efficiency. Apart from this, whether you opt for a temporary or permanent solution, your pipe can create specific issues if it needs to be updated. So ensure that you are buying a pipe that is durable enough so that it does not require replacement.

Sometimes you can also use a mixture of chemicals like Ammonia or bleach to unblock the drain pipe and enhance its efficiency. This will help the drainage system to release the pressure that may be built up in the pipe.
