What is a Bathroom Sink Pop-Up Drain
A bathroom sink pop-up drain is an essential component that allows water to drain out. It consists of a stopper that can be raised or lowered by pressing down by hand, to start or stop the flow of water. Many have a basket built into the stopper which catches debris, and can be easily removed for cleaning. Unlike previous style drains, pop-up drains don’t require rods and levers between the faucet and drain for control.
Why Install a Bathroom Sink Pop-Up Drain?
Installing a bathroom sink pop-up drain is a simple and effective way to improve the functionality and aesthetics of your bathroom. It allows you to easily control the water flow and with the basket option prevents clogs by catching debris.
Many newer design bathroom faucets require pop-up drains because they are not equipped with rods and levers to control the older type drains.
Tools and Materials - affiliate links
Before you begin the installation process, gather the following tools and materials as needed:
- New pop-up drain (see note)
- Large adjustable wrench
- Channel lock pliers
- Scotch-Brite pad
- Plumber's (Teflon) tape
- Plumber's putty
NOTE: There are two types of pop-up drains. One has a drain hole in its pipe below the upper flange, and the other does not. The one with the hole is for a sink with a built in overflow hole (most common, and clearly visible). The other is for a sink without an overflow hole (not so common).
Step 1: Remove the Old Drain
To be safe turn off the hot & cold water supply valves which feed the faucet hoses. Place a bucket under the sink to catch any water that may spill out. If too tight to turn by hand use channel lock pliers to loosen and remove the nut that connects the pipe from the P-Trap to the drain. The P-Trap includes a U-shaped pipe which connects to the pipe coming out from the wall.
Then with your adjustable wrench remove the nut securing the drain to the sink, and remove the drain up and out.
NOTE: All of the PVC or metal pipe connections use seals. Take photos! And note all seal positions and condition during disassembly to aid in a leak-free reassembly. Replace seals and pipes as needed - affiliate link.
Step 2: Clean the Sink
Remove any debris or old plumber's putty from the sink surface. Clean the sink top and bottom where the drain seals thoroughly. Scotch-Brite works well.
Step 3: Apply Plumber's Putty
This only applies to drains without an upper seal which fits beneath the upper flange. Most new drains are equipped with seals and do not require putty.
Take a small amount of plumber's putty and roll it into a thin rope. Apply the putty around the bottom edge of the new pop-up drain flange. This will create a watertight seal when the drain is tightened down.
Step 4: Install the New Drain
Insert the new pop-up drain into the sink drain hole. Make sure it is centered, and press it firmly into place. Remember to align the hole in the drain pipe with the sink’s overflow hole (if equipped).
Remember that most new drains have upper and lower tapered rubber or silicone seals. The upper seal is tapered down and the lower is tapered up. After installing the drain with the top seal in place, install the lower seal (any given washers) and the retaining nut. Tighten the nut securely, but not excessively. Hold drain to retain overflow hole alignment while tightening.
Step 5: Test the Drain
Turn on the water supply and let the water flow into the sink. Check for any leaks around the new pop-up drain. If you notice any leaks, tighten the nut further or apply more plumber's putty as needed. Sometimes putty or Teflon tape may be required on the drain threads for problem leakers.
