The drip, dripping from a kitchen faucet is no fun. It can be annoying, but the good news is that the problem that you can fix it in a short time.

We will show you how to get it done quickly, cheaply and in record time.

The tools you will need include:

  • Replacement Parts
  • Allen wrench
  • Pliers
  • Screwdriver

First things First

Before you start, check to see exactly which part of the faucet is leaking. Some leaks can be from the spout or the base of the tap.

Turn off the Water

Stop the water supply either from the vale under the sink or the valve to your home.

After the water is off, let the water drain from the faucet to help release the pressure in the pipe.

Next, use a cloth or a filter and cover the drains so that the small parts do not go down the shoot.

Helpful Hint:

Take note of the parts and how they fit together.  You can take a picture, or lay them on a towel or cloth in the order you took them off. It will help you re-assemble them in the same order.

Make a Check

Now the parts are off, check inside the valve for damaged or corroded parts.

Clean up

Debris and mineral deposits can block the holes in the pipe.

  • A few scrapes with a penknife or screwdriver can clear them quickly
  • Clean the area with a cloth and use some vinegar to help loosen any build-up present

Reassemble the parts and slowly open the shut-off valve to switch the water on. Let the tap run to release any build up of air in the pipes.

Check for the flow in the pipeline

If it is slower than usual, you may need to take the aerator out and clean it.

Matching your replacement faucet

All faucets are not the same. Some may be:

  • Rotary shaped
  • Cartridge-style
  • Ceramic

Make a note of the faucet’s make and model number beforehand. If you’re not sure about a replacement faucet, take the old part to the store and match it up with a new one. Some models may vary. Look for the best possible fit.

How to install a rotary ball faucet

Some rotary faucets have a brass or plastic ball that rotates in a socket to regulate the water temperature and flow.

Troubleshooting

  1. If there’s a leak near the base of your faucet handle, you may need to detach the handle and tighten the ring.
  2. Turn it until it stys firmly in place. If the spout is leaking, the seats and springs may need replacing.

Reassembling

  • Align the strings in the grooves, then connect the rubber seats.
  • Position the pin and ball in the slot and secure them in place
  • Attach the lug to the plastic cam. Ensure the groove is inside the valve
  • Position it on the ball

After you thread on the cap, re-inforce it with a spanner. Check for any leaks by allowing the water to run for a while.

If the ball is leaking, tighten it with a spanner until the leaking stops. Re-attach handle.

How to install a cartridge faucet

Over time leaks may occur at the hot or coal mixer or the spout.

The O-rings may need replacing, or the full cartridge is damaged. Match it with a new one at your local store.

Loosen the cartridge with a spanner to remove it. Put a little pressure on the handle until it comes off.

Reassembling

For this type faucet, reassemble the parts in the opposite order. Before you insert the cartridge, pull the stem up.

Next, align it with the brass retainer clip. If it shifts, give it a few twists to steady it.

  1. Rotate the cartridge with needle-nose pliers or plastic spanner. Slip the brass clip into the slot to help to secure it into position.
  2. Locate the notch above the stem of the faucet, and turn the notch towards you.
  3. Put the rest of the parts together and re-connect the handle.

Helpful Hints:

  • Check the directions for the stem in your manual
  • Test the faucet to see if it is working correctlyor if there are any leaks
  • If the hot and cold water is in the opposite order, take off each part and turn the stem until it sits in place

How to install a ceramic type faucet

Ceramic style faucets have discs inside the tap that regulate water flow. The valve is usually durable but may need fixing at some point.

Faulty rubber seals or a split disk inside the cartridge may cause the faucet to leak.

Splits or cracks may be difficult to detect, so it’s safer to replace the seals and re-attach the faucet.

  1. As you switch the water on, let the faucet remain open to allow pent-up pressure to get out.
  2. A full blast of air pressure may burst the ceramic parts.
  3. When the water flow evens out, turn the faucet off.

If the spout is leaking

Wear and tear on the O-rings may cause the spout to leak.

  • Take out the cartridge and handle, then pull the spout out
  • Match it up with a replacement at the store or buy a new kit if available

Troubleshooting

A clogged diverter valve may slow down water flow in the sprayer.

Look for the diverter close to the spout.

Give the sprayer a thorough clean with vinegar or change it if needed.
