The Only Pop-up Waste Drain Resources You Will Ever Need

In plumbing, the word ‘Waste’ refers to a metal tube that you see at the base of a basin, sink, or sanitary unit. The ‘Pop-Up’ waste drain is one of them and the most popular one. In this resource, you’re going to know every little thing about pop-up waste. So, let’s dig in. 

What Is A Pop-Up Waste Drain?

pop-up waste drain is a mechanical device that joins a sink or basin to a plughole waste pipe. The purpose of a pop-up drain is to block the water in the sink… and release the water to the waste pipe from the sink. A lever-type rod usually controls the pop-up waste. For your pull and push to the lever, it opens and closes the pop-up waste to control water flow.


Pop-up wastes have two types, ‘Slotted’ and ‘Unslotted.’ Slot means the notches cut in either side of waste. Slotted ones are suitable for ‘overflow’ basins and unslotted ones for basins with no overflow.

Parts of a Pop-Up Waste

You can divide the pop-up waste drain system into two different parts. One is the total ‘waste unit,’ and the other is the ‘lever unit.’

Waste unit means the whole waste mechanism. At the top of the waste, there is a ‘push button.’ There is a brass tube installed (inside of the waste body). It’s the ‘stopper.’ There is a hexagonal nut on the outside, and an O size rubber (washer) is attached to the waste body. And after that, there is a hole like a tubewell on the lower section of the waste. This hole connects the lever unit with the waste unit.

In the lever unit, there is a ‘lift rod.’ You may found it behind the tap or faucet. The lift rod is connected with the ‘clevis strap.’ A clevis strap is a metal sheet with many holes to adjust the lift rod’s height with the waste. Similarly, the clevis strap is attached with another rod at the bottom. It’s s’ pivot rod‘. The other end of the pivot rod joins the stopper bottom. There is a ball at the waste hole (tubewell type hole), named ‘seal,’ which controls the pivot rod’s movement.

How a Pop-Up Drain Works

The working procedure of a pop-up waste drain is pretty simple. 

When you pull the lift rod, it also lifts the clevis strap. Similarly, the clevis strap lifts the pivot rod. Since the pivot rod is attached with the stopper through the seal, the other end goes down when one end goes up. Thus it drags the plug down. As a result, the waste pops down and closes the drain entrance.

When you push the lift rod down in the same vein, it drags the ‘clevis strap’ and ‘pivot rod’ down. So, the other end of the pivot rod goes up and pushes the stopper up. Therefore, the waste pops up and opens the path for water to flow.


You can easily install a pop-up basin waste in your sink or basin even if you don’t have any plumbing knowledge

First, disconnect the lower section, hex nut, and washer of the waste by unscrewing them. Then install the seal and pivot rod through the waste body hole. Now, place the upper section of the trash in the sinkhole and connect the lower part with it from underneath the sink. 

Now it’s time to connect the lever unit. To do that, firstly, put the lift rod inside from behind the faucet. Secondly, click the clevis strap to it at the bottom. Now place the pivot rod in the perfect positioning hole of the clevis strap. Therefore, they can work with each other efficiently.

All done here. Now check it by pulling and pushing the lift rod. If everything’s doing well, then Congo, you’ve done it.

Pop-up waste drain cleaning is important to avoid unwanted blockages and failures. 

To clean it, first, remove the pivot rod from the bottom of the sink. To remove the pivot rod, unscrew the seal part and unlock the pivot rod from the waste. Now, please take out the push button by undoing its spins anticlockwise. You can see the stopper in you see inside of the waste. 

Pull out the stopper from the waste. Use an old toothbrush and a piece of cloth to clean the plug and inside of the waste. Then follow the above steps reversely to re-assemble the waste again.

Uses and Benefits

Pop-up waste drains are mainly used in kitchens and dining space basins. This waste allows you to block the drain pipe from the sink to fill the sink with water… and clean your dishes and other things properly. When you finish your work, you can release the water by simply pushing the lift rod. 

Another good thing is, you can prevent unwanted flooding with the slotted ones. In case of a rush, you forgot to turn off the tap. Once your sink is full, the slotted waste will release excess water.
