How To Fix A Leaky Faucet – Step by Step

Leaks may discolor sink surfaces, erode drains, waste energy and sewer pipes (in the case of a hot water leak), and overall cause problems for you and your property. We’ve collected a list of some causes and how to fix a leaky faucet to help you save money.

Causes

We need to understand the particular reasons why tap drips. The following are some of the most frequent explanations:

The O Ring Has A Problem

Checking the O Ring
Checking the O Ring

The water tap handle is held in place with a stem screw. The O ring is a tiny disc linked to this stem screw. This is a critical region where leaks can occur. Over time, the O ring might become loose or worn out, causing the faucet to drip near the handle.

Valve Seat Corrosion

A valve seat connects the tap and the spout in the compression mechanism. The valve seat might erode due to the accumulation of water sediments, resulting in leaking around the spout region. With the aid of a competent plumber, clean regularly.

Worn Out Washer

A worn-out washer is one of the most common causes of dripping faucets because it is forced against the valve seat each time it is operated, causing it to deteriorate due to friction. To halt leakage, replace old rubber washers. 

Installing A Washer Incorrectly

A leaky spout might occur if it is not correctly installed or is the incorrect size. 

The Water’s Pressure

Your home’s water pressure could be to blame if the faucet drips only at specific times of the day or when the faucet handles are moved in a certain way.

Non-assembly parts

Over time, the stream screw’s adjustment nuts for ring and packing have the potential to loosen, resulting in a leaky sink handle. A leaky hydrant can usually be fixed by tightening or replacing the packing nut.

A Broken Cartridge

You have a cartridge-style faucet if it has two handles for hot and cold water. A valve controls the cartridge’s water flows into the spout on each handle. If water is dripping from your valve, it is an indication that the cartridge has been damaged.

How To Fix A Leaky Faucet (Double-Handle)

Ceramic disc, rotary ball, and cartridge are the three basic types of faucet structure in the process of learning how to fix a faucet. All of these terms apply to the internal design of the faucet, as well as how it regulates water temperature and flow. 

Because they’re all created differently, they’re all vulnerable to distinct issues. It can help to know what type of faucet you have in determining what type of repair is required.

Keep in mind that the bodies of certain cartridges & disc bodies/cylinders made of ceramic may resemble each other. The cartridge body has no moving parts in most circumstances. Moving pieces rotate to open the apertures on the bottom of the ceramic disc body/cylinder.

Kitchen and bathroom water taps, including baths and showers, may all be fixed using these instructions. The methods outlined here are standard but always refer to your tap’s manufacturer’s instructions.

Find The Leak

Shut off the water supply valves one at a time to figure out which side of your water tap is leaking. 

Turn off all supply valves when you’ve figured out which side is leaking.

Cut the water main if your valves have become clogged. Because you won’t be able to tell if it’s leaking from the cold or hot side, you’ll have to replace the hardware on both sides.

Remove The Faucet’s Parts

To begin, disassemble the faucet.

Step 1

Turn the water tap knobs to the “on” position to discharge any remaining water. Close the drain and cover the sink with a towel to preserve any spilled objects from the surface.

Step 2

Remove and examine the aerator for any damage. Dip a cloth and wrap the aerator in vinegar to dislodge mineral deposits. Twist the aerator gently with a cloth and pliers after an hour.

Step 3

As you remove the old hydrant, lay the components out on a flat surface and snap a photo for reference. Put those components in Ziploc bags and bring them with you to the hardware store when you go shopping. 

Although you may only need one item, it’s probably advisable to get a whole new kit and renew everything, including the aerator, if yours is broken.

Faucets With Ceramic Discs

Soak your old aerator into white vinegar to erase buildup and residues. Before you reinstall it, please give it a good rinse.
