Got a dripping faucet?
We’ll show you how to fix three types of
single handle faucets—ball, cartridge and
ceramic disc.
First, determine the source of the leak.
A leaky spout means damaged parts inside the
body.
A leak at the base means damaged seals around
the body.
Turn off the shut off valves.
If they’re stuck, turn off the main water
valve.
Turn on the faucet to release any residual
water.
Close the drain and place a towel in the sink
to help protect it.
Also remove the aerator.
If it’s stuck, soak a towel in white vinegar
and wrap it around the aerator for about an
hour.
After an hour, gently remove the aerator with
a towel and pliers.
As you’re taking apart the faucet, lay the
parts in order and snap a picture to help
with reassembly.
Put the parts in a plastic bag to take to
the store.
You can replace one specific part, but it’s
usually best to get a kit and replace all
the parts.
Also buy a new aerator if yours is damaged.
Keep in mind these directions are typical
but check the manufacturer’s instructions
for your faucet.
On ball valve faucets, loosen the set screw
and take off the handle.
Then take off the cap.
To repair a leaky spout, remove the cam, washer
and ball.
Note how the holes in the ball line up with
the faucet body.
Use a small screwdriver to remove the seats
and springs.
To repair leaks at the base, slide off the
spout, then replace the O-rings.
Add a little plumber’s grease and replace
the spout.
Put new seats on new springs and put them
back in place.
Replace the ball -- making sure the holes
are lined up.
Then replace the washer and cam, and reassemble
the rest of the faucet.
For cartridge faucets, remove the cap and
take out the screw and clip.
Then take off the handle and trim ring.
Unscrew the retainer and pull out the cartridge.
Insert a new cartridge.
Then reassemble the faucet.
To repair a ceramic disc faucet, remove the
handle, and trim ring.
Unscrew the retainer nut, and pull out the
cylinder.
Instead of repairing the discs on the bottom
it’s best to install a new cylinder.
Put the faucet back together, and turn it
on.
For all faucets turn on the supply valves
slowly and without the aerator let the water
run for a few minutes to flush out any debris.
Clean a dirty aerator by soaking it in white
vinegar.
Rinse it and screw it back in.
Now your faucet should be working like new.
