Faucets are one of the most commonly used fixtures in the home, so it’s no surprise that they are also one of the most common sources of leaks. Faucet leaks can range from a tiny drip to a constant stream and can occur anytime. If you notice a leaky faucet, you must take action immediately. In addition to wasting gallons of water, a leaky faucet can also cause damage to your home and increase your water bill.

You may only sometimes be able to tell when your faucet is leaking, but you can check a few key places.

Leaks From the Spout

Faucet leaks from the spout are the most prominent and visible place. These are the most common faucet leaks; over time, small drips can worsen and eventually increase your water bill. By identifying the source of the leak and taking measures to fix it, you can prevent further damage to your home and save money on your utility bills.

A few things can cause a faucet to leak from the spout.

  • A worn-out washer is often the culprit, as it can no longer create a tight seal against the valve seat. Over time, mineral deposits can build up on the valve seat, preventing the worn-out washer from making a tight seal.
  • Another possibility is that the valve seat itself is damaged or broken.

There are a few different ways to fix a leaky faucet, depending on your type of faucet.

  • A compression faucet

If you have a compression faucet, you’ll need to replace the worn-out washer. Start by shutting off the water supply, remove the faucet handle and unscrew the packing nut. Next, remove the faucet stem and check the condition of the washer. If your faucet is worn or damaged, replace it with a new one. Reassemble the faucet and turn on the water supply.

  • A cartridge faucet

If you have cartridge faucets, chances are you just need to replace the cartridge. Begin the process by shutting off the water source, then take off the faucet handle. Next, use a pair of pliers to remove the retaining clip, then pull out the old cartridge. Insert the new cartridge and reassemble the faucet.

  • A ceramic disc faucet

If your faucet has a ceramic disc valve, you’ll need to replace the O-rings. Before you begin, turn off the water supply and detach the faucet handle. Next, unscrew the bonnet nut and check for any damage on the O-rings. If needed, replace the faucet with new ones, reassemble the faucet and turn on the water supply.

Tips

Before starting any plumbing repairs, always remember to turn off the water source. Otherwise, you could flood your bathroom (or worse!).

Leaks Around the Base of the Faucet

If you notice water puddles around your sink or on your countertop, there is likely a water leak at the base of your faucet. These leaks are often not too noticeable because users tend to splash water around the basin and the bottom of the faucet. However, if you frequently see puddles of water on the counter around your faucet, this area may leak.

There are several reasons why a leak might occur at the base of your faucet.

  • The washer, which is a small disk that seals the connection between two parts of the faucet, may be worn out or damaged.
  • Second, the packing nut (a small nut that holds the washer in place) may be loose.
  • Third, the O-ring (a small ring that seals the connection between the faucet and the supply line) may be damaged.

Leaks Under the Sink

Water leaks from underneath sinks and faucets can be difficult to detect, as most people only regularly check under their sinks. However, these can be some of the most dangerous leaks, as the water has nowhere to go and will pool on the floor. If you have a water leak under your sink, you must act quickly to prevent further damage. Some possible causes of water leaks under sinks include:

  • A loose connection between the water supply line and the shut-off valve
  • A cracked or damaged pipe
  • A leaky shut-off valve
  • A faulty P-trap

If you have a water leak and don’t know the source, it’s advisable to consult with a plumbing specialist. They will help determine the root of the problem and how to efficiently resolve it.

A loose connection

A loose connection between the water supply line and the shut-off valve can cause leaks in the faucet. With just a few tools, anyone can quickly fix this in a few minutes.

  • First, turn off the water in the sink. There will be a shut-off valve under the sink or behind it in a cabinet. Once the water is off, open the faucet to release any water pressure in the lines and ensure no water runs into the sink.
  • Next, use a wrench or pliers to tighten the connection between the water supply line and the shut-off valve. Hand-tighten it as much as possible, then give it another 1/4 turn with the wrench for good measure.
  • Finally, turn the water back on and check for leaks. If there are still leaks, try tightening the connection again. If the above method doesn’t work, you’ll need to replace the faucet with the worn-out washer or the o-ring seal on the shut-off valve.

A cracked or damaged pipe

If you have a leaky faucet, there’s a good chance that the problem is with the pipes. Due to age, wear and tear, or extreme weather conditions, cracks and damage to pipes can occur over time. While it’s best to call a professional plumber to repair damaged pipes, there are some steps you can take to fix the problem yourself.

  • First, locate the source of the leak. This may be easier said than done, as leaks can often be hidden behind walls or cabinets. If you’re wondering where the leak is coming from, try shutting off all the water in your home and then opening each faucet one by one until water starts dripping from that specific faucet.
  • After identifying the leak’s location, use the shut-off valve to turn off the water to that faucet.
  • Use a putty knife or other object to fill in any cracks or gaps in the pipe after the super glue has dried.
  • Once the cracks are filled, turn on the water supply and test out the faucet to see if the leak has been fixed.
  • If the leak persists, there is likely more severe damage to the pipes, and you will need to call a professional plumber.

Following these steps should help you fix a leaking faucet caused by cracked or damaged pipes.

A leaky shut-off valve

It’s frustrating when you turn on your kitchen or bathroom sink only to find that the water won’t flow because of a leaky shut-off valve. Luckily, this is a problem you can quickly fix with just a few tools and supplies. Here’s how to do it:

  • First, turn off the water in your sink by finding the appropriate shut-off valve and turning it clockwise.
  • Remove the handle by unscrewing one or two screws, depending on your faucet type.
  • With the handle removed, you should be able to see the packing nut. This is what’s causing your leak, so you’ll need to remove it. Use a wrench to loosen it until you can unscrew it by hand.
  • Once the packing nut is removed, pull out the faucet stem and inspect it for damage. You’ll need to replace the faucet stem if there are cracks or pitting. Otherwise, clean it off and reassemble your faucet.
  • Keep the water running, and check your faucet to see if the leak has stopped. If it hasn’t, continue these steps until the issue is fixed.

Fixing a leaky shut-off valve is a relatively easy task that anyone can do with little time and effort. So next time you’re dealing with a dripping faucet, don’t call a plumber – follow these steps, and you’ll have it fixed in no time!

A faulty P-trap

Most homeowners will experience a leaky faucet at some point. In most cases, the cause is a faulty P-trap. The P-trap is a curved section of pipe that holds water and prevents sewage gases from entering the home. Over time, the P-trap can become clogged or eroded, causing leaks. Thankfully, fixing a leaky P-trap is a relatively easy DIY project.

Here are the steps you’ll need to take:

  • Turning off the water in your sink is as easy as finding and flipping the knob or lever underneath it.
  • Place a bucket under the sink to catch any water that may drip out.
  • Disconnect the P-trap from the drainpipe and clean out any debris clogging it.
  • Reconnect the P-trap and tighten all the connections with pliers. Be sure not to over-tighten, as this can damage the pipes.
  • Check the water supply for any leaks, and you will likely need to replace the P-trap if there are still leaks after turning it on.

Wrapping up

Diagnosing and fixing a leaky faucet can be tricky, but it doesn’t have to be. By following these steps and taking the time to diagnose the source of the leak properly, you can quickly fix the most common faucet problems yourself.
