Now let’s move on to the main steps.

Step 1: Disassemble Your Old P-Trap

First, you need to drain out your old p-trap. Put a basin underneath your p-trap. You may remove all of these slide joint nuts by using your channel lock pliers.

But some like to have a p-trap in their bathroom sink. You can install your p-trap in your bathroom sink.

There’s a total of six nuts on this assembly that I have removed. Depending on how yours look like you can take these off as it is required. 

Once you take these off there should be some water that is trapped on the p-trap. So just drain those out. Also, disassemble the mechanism that controls the draining plug. The drain pipe is located at the bottom of the sink. Including the joint ball valve that is controlling that drain plug. 

Once you disassemble that, you can take out the drain plug easily. You can unscrew that drain pipe and also the drain frame cap on the top.

Step 2: Assemble the Bottle Trap

You can now use the bottle trap pop-up drain plug. It has a nice satin finish on it. It comes with an inch and a quarter pipe that will attach to the drain piping. 

It has a pop-off drain plug feature. You’ll find the drain cap protected with a plastic cover. The entire assembly has a pop-up feature. Once you press and depress onto this it goes up and down.

Once you open that bottle trap there is also an inch and a quarter piping included. It will attach to the drain piping.

Step 3: Apply Plumbers Putty on Your Bottle Trap

Let’s disassemble everything including the nut and also all the plastic rubber washers. You can use your Plumber Putty. It will help you to prevent any kind of leaks. It has a clay-like texture. I like this because it is the strain-resistant type. It doesn’t leave any in your porcelain. 

To avoid any kind of leaking plumber’s putty is a good option. Whether it is a faucet or your toilet you can use it. However, for leaking toilet tanks, use rusted bolts to fix it.

What you need to do is pretty much take out a little bit at a time. Just pretty much knead it like a dough. Here you can just roll it into a little tiny shape of a snake. After you roll it you can apply it to the bottom of the drain frame. 

To have enough to cover the surface area, you can apply a rather thick layer there. When you do that make sure you use a microfiber towel to clean off the perimeter area. That is where you’re going to be placing the drain frame. 

To ensure that it is perfectly placed, position it in the exact center. And then apply pressure directly beneath it. Make sure you apply a nice amount of pressure. You can take out the excess which pretty much kind of squeezes off the side. Now don’t throw this away, this is still good. 

To prevent drying out, you can put any leftover plumber putty back into your container and seal it. The rest you are just going to clean off with your microfiber towel. Continue pressing onto it just in case some excess comes out. 

You are going to take another set of plumber putty and roll it like a snake. This step is very important. Because if you don’t apply this before it will start leaking. Apply the plumber’s putty along the perimeter directly underneath the drain pipe.

Make sure you tighten it with your channel lock pliers. Make sure to remove the extra material since there will be some while you tighten the nut. 

You can do it with your fingers and then you can reuse this excess. Store it again in its container. You can use your plumber’s putty in the future.

Step 4: Take Off The Extra Piping From Drainage

Take off the extra piping that is coming from the drainage. The cap that comes with the package, you can remove quite quickly in order to flush. For that, you can use the handheld hacksaw. 

Take out the hacksaw itself to maneuver it a lot better. Take off the excess making it flush with the wall. Here is a key trick, I like to use petroleum jelly. It is a kind of lubricant that you can apply to the kit’s included plug.

This rubber-like plug can be placed directly up against the wall where the drainage has stopped. This is going to seal what you’ll do is put petroleum jelly on it and around this. Insert right into the drainage pipe hole. You can easily slide it in there without any struggle. 

Since the bottle trap pipe is so short, you’ll need to get an extending pipe. So that it will reach this drain outlet. For that, you can use a west brass inch and a quarter 12-inch slip joint extension tube. 

To reach the outlet, you will simply hook this to a drainage pipe hole as an extender. And you will also cut this to size. The extension pipe goes underneath.

Step 5: Inserting The Extension Pipe

Insert the nuts that were provided with the extension pipe and also with the rubber gasket. Just slide it on there and then slide it onto the extension tube. Take the barrel and then insert it onto the extension pipe. Then you’re just going to test fit it right for now. 

You may face that it won’t fit with the drain hole. The reason why this is 12 inches is so that you can trim anything for excess. You can mark it with masking tape where that barrel is going to be sitting. 

Then you’re going to take this off once again so that you can test fit it. Now you can use the pipe that was provided. Attach it to the barrel and then use a leveler. So that you know where it is to be cut off. 

Mark it with your masking tape after making sure it is perfectly level. So that you know where you are going to cut off the excess part. Then you can match it with the drain hole.

Once it is finished, remove the old masking tape. Leave the one you originally installed, and remove the piping you added.

You can take a two-by-four so you can gain leverage. You can cover it with a microfiber towel. So it doesn’t scratch the finish of your matte black finish on your piping. Use a 12” hacksaw and handheld hacksaw. Switch it in and off and which one’s better to use is totally up to you. 

I would like to finish it with a handheld hacksaw. You can deburr the edges of your assorted grit sandpaper. You can fit it once again, make sure you take off that nut and then tighten it. As you go, take the barrel to unscrew the top screw nut and then insert it. 

Insert the barrel first, then step inside so that it is correctly positioned with the drain hole. Once that’s been completed, you’ll take the barrel off once more.

Step 6: Installing The Barrel Underneath Your Faucet

You have to go through a lot of repetition. But this is the proper way to do it. Take off the nut that’s screwed onto the drain hole plug. Now your excess inch and a quarter pipe insert the drain gasket. Make sure the nut is tight enough; otherwise, you need to mark it similarly to the last time. For that, you need to use our masking tape. 

Take off the drain nut and then take it off once again. To measure the distance, reassemble it and tighten the barrel to the quarter-inch pipe.

Once you get the measurement, mark the number you just got. You can put an extra one or two inches. This will pass via the plug’s exit, note the number you got on the measuring tape. 

Now that you mark it, you can use this quick method. Use your handheld hacksaw again to deburr the edges again with assorted grit sandpaper. Take off the piping once again because you’re going to be maneuvering the drain gasket. 

It is very movable after you insert it. Insert petroleum jelly at the tip of the quarter-inch pipe. So that this can slide through that drain plug hole. It’s very important that you have the drain hole flushed so that this covers it right through. 

Getting the quarter-inch pipe through that hole is much simpler when you’re using that petroleum jelly. 

The drain screw should now be installed, followed by the gasket and the barrel being inserted straight through. After that, you’ll move it so that it fits over the inch-and-a-quarter pipe. 

Step 7: Testing The Disc Drain Plug

Before you tighten the nut, you’ll use your leveler to make sure that everything is nicely leveled. Check again to make sure it’s perfectly centered with the level. Once everything is level and snug in the nut.

Now you can take your drain cap and pretty much screw it right on. What you’re going to love about this feature just pretty much pops on and off. 

Finally, test if everything is nice and tight so there are no leaks and turn on your faucet. While it is running check below for any types of leaks you can see
