Most times, drips or leaks at the end of the spout can be traced back to the cartridge underneath the handle(s). It sounds like either one or both cartridges in your faucet may need to be replaced. Don't worry:
this is a pretty simple fix. We'll walk you through it step-by-step.

How/where is it leaking from?
My Single Handle Control is Leaking at the Spout, What's Wrong?
Problem: My bathroom faucet is leaking at the spout
Solution: Replace your Single Control Cartridge
Find your cartridge
The first thing you need to do is figure out what replacement cartridge(s) you need. To do that, first, find your faucet by either typing in the model name/number in the search bar at the top or browse through our faucet listings. (Link to centerset faucet page) If your faucet is more than five years old, you may have to check the "show discontinued items" box at the top to find it. Once in there, find a document called "Maintenance Guide". There should be a diagram on there with links to all the parts, including the cartridge(s) you need.
Turn off the water supply
Once you have your cartridge, we're ready to make the repair. First things first: go under your sink and turn off your water supply at the wall by turning the knob on the stop clockwise. Turn on your faucet to drain out residual water and also to check to make sure the water is completely off.
Remove the handle(s)
Next, we're going to remove the handle. Either on the back of the faucet or under a small cover on the front (which you can pop off with a small flat head screwdriver) will be a set screw. Using an Allen wrench (usually 3/32", but possibly smaller), loosen the set screw by turning it counter clockwise until you can lift the handle off of the faucet. Be careful not to completely remove the set screw from the handle, as it will make it more difficult to replace later. Set the handle aside.
Remove the dome cap
Next, unscrew the dome cap underneath the handle by turning it counter clockwise by hand if possible. If you can't turn it by hand, place a towel over it and then try to unscrew it with an adjustable wrench to avoid damaging the finish. Now remove the retainer nut underneath the dome cap by twisting it counter clockwise by hand or very gently with a wrench. Place both the dome cap and retainer nut aside for later.
Remove the cartridge
Now we're ready to remove the cartridge. Some cartridges may have a screw in the top of the cartridge. Just use a small Phillips head screwdriver to remove the screw if it's there. On all faucets, pull the cartridge straight up to remove it, being careful to make sure you remove all pieces (some cartridges have springs at the bottom which may have come loose over time).
Install the new cartridge
Now it's time to put the new cartridge in. Drop the cartridge in, making sure it's lined up properly. If it needs a screw at the top, insert it now and tighten with a small Phillips head screwdriver.
Replace the dome cap and retainer nut
Replace the retainer nut first by turning it clockwise by hand. Next, put the dome cap back on and tighten clockwise by hand.
Put the handle on
The final step before you turn the water back on is to replace the handle. Place the handle on the cartridge so that the top of the cartridge slides into the slot on the underside of the handle. Once the handle is snugly fit onto the cartridge, take the Allen wrench and tighten the set screw by turning it clockwise until it's tight. If there was a cover over the set screw initially, snap the cover back in place by hand.
Turn On Water
Make sure the handle is in the off position, then turn on the water by turning the knob under the sink counter clockwise. To test to make sure the leak is fixed, turn on the water and let it run for a minute. Turn it off and check if the faucet is still leaking.
If the faucet is still leaking, you might have another issue. Feel free to give us a call at 1-800-PFAUCET to get additional help. You can also contact us via email here.

My Single Handle Control is Leaking Under the Counter, What's Wrong?
Problem: My bathroom faucet is leaking below the counter
Solution: Find out where the leak is originating, please follow the walk through below.
We're sorry your faucet is leaking. Before we can tell you how to fix it, we need to figure out where the leak is coming from. Please follow the steps below to troubleshoot:
Shut the water off
We're sorry your faucet is leaking. Before we can tell you how to fix it, we need to figure out where the leak is coming from. First things first, let's shut the water off from both the hot and cold sides. Do this by going under your sink and turning the knobs on the angle stops by hand clockwise until they won't turn anymore. Note that, if your stops won't turn by hand, you can CAREFULLY use a wrench to try and get them to move but, once you get them turning, we highly recommend turning them the rest of the way by hand (trust us: you do not want to break an angle stop!).
Dry everything off
Next, take a towel and dry off everything connected to the faucet and sink, including the underside of the faucet, the supply lines, the drain pipe and the angle stops. In particular, make sure any connection points (angle stop to supply line, supply line to faucet, etc.) are dry.
Test for leaks - cold
Now we're going to check to see if we can find the leak. Start by turning on the cold water (usually the stop on the right side under the sink) first by turning the knob on the angle stop counter clockwise by hand. Now look carefully at the underside of your sink, particularly the connection points.
At the angle stop
-
Tighten supply line nut
If it's at the angle stop, there's a chance your supply line just needs tightened. Turn the water off at the angle stop, then take an adjustable wrench or groove joint pliers and carefully try to tighten the supply line nut until it feels snug. Dry off the area around the nut, then turn the water back on and check for a leak.
-
Replace supply line
If it's still leaking at the supply line, the seal on the supply line might be worn. You'll need to replace the whole supply line (don't worry: it's a pretty cheap fix!). Turn off the water, then disconnect your old supply line by unscrewing it at both ends (angle stop and faucet). We would recommend bringing the old supply line with you to your favorite home improvement retailer to make sure you get an exact replacement. Once you have a new supply line, simply attach it to both the faucet and the angle stop per the instructions on the supply line, then turn the water on and check for leaks.
-
Water still leaking
If the faucet is still leaking, you might have another issue. Feel free to give us a call at 1-800-PFAUCET to get additional help. You can also contact us via email here.
At the underbody
-
Tighten supply line nut
If it's at the point where your supply line connects with the faucet, there's a chance your supply line just needs tightened. Turn the water off at the angle stop, then take an adjustable wrench or groove joint pliers and carefully try to tighten the supply line nut until it feels snug. Dry off the area around the nut, then turn the water back on and check for a leak.

At the Supply Line
Replace supply line
If the supply line itself is leaking, you need to replace it (don't worry: it's a simple, cheap fix). Turn off the water, then disconnect your old supply line by unscrewing it at both ends (angle stop and faucet). We would recommend bringing the old supply line with you to your favorite home improvement retailer to make sure you get an exact replacement. Once you have a new supply line, simply attach it to both the faucet and the angle stop per the instructions on the supply line, then turn the water on and check for leaks.
Test for leaks - hot
If you didn't see water when the cold water was on, you should now turn on the hot water (usually on the left side under the sink) by turning the knob counterclockwise by hand. Now look carefully at the underside of your sink, particularly the connection points.
If you see water dripping, try and figure out exactly where it's coming from. Please click here to troubleshoot and keep in mind your are testing for leaks on HOT water.
Test for leaks - drain/sink
If you didn't find any leaks after turning on both the hot and the cold water, the next thing to check is the drain and the sink area. To do this, turn on the faucet (we recommend cold water) and look underneath the sink to see if you see any water dripping from anywhere. If you have a standard pop-up drain with a rod, make sure to check the back of the drain pipe where the rod goes in.
Leak from pop-up rod
-
Tighten pop up rod nut
If water is dripping from where the rod goes into the drain pipe, check to make sure the nut is properly aligned and tight, especially if you recently took up the pop-up rod out to clean your drain. First, turn the faucet off if it's still running. Now reach back behind the drain pipe, find the nut and turn it counter clockwise by hand until it's tight (tip: you might want to use a mirror to help you see it). Turn the faucet on and see if it's still leaking.
Check for cracks
If it's still leaking, check to see if the area around the hole is cracked (again, you can use a mirror to get a better look). If it is, you'll need to either patch the cracks with an epoxy or replace the drain pipe. If you don't see any cracks, you might need to replace the pop-up assembly.

Replace the pop-up assembly
If you need to replace the pop-up and your product is still under warranty, call us at 1-800-PFAUCET and we can help. Or feel free to email us.
Leak from elsewhere on pipe
Patch or replace pipe
If you have a leak in the drain pipe, you can try to patch or re-seal the pipe using an epoxy, or you may have to replace the entire drain pipe if the pipe has too much damage.
Sink itself is leaking
Patch/caulk the leak
If the leak is coming from in or around your sink rim, find the source where the water is coming from and try to patch or caulk the area to fix the leak. Note that sinks--especially ceramic--can have some variety in the dimensions of the bottom hole or in the smoothness of that area. If you are installing a new drain and there is water dripping from the area where the drain seats on the sink, managing an extra quarter turn to make sure the washer seats properly oftentimes fixes the problem
