Every hardware store makes it look easy, and every YouTube tutorial skips the part where something goes wrong. The truth is that some faucet repairs are manageable for a handy homeowner, and some turn a dripping faucet into a flooded cabinet. At Mr. Rooter Plumbing, we've done enough faucet replacement work to know where the DIY line is and what happens when people cross it. Keep reading for an honest breakdown of what you can probably handle, what you can't, and how to know the difference before you're in over your head.?

What's Causing Your Faucet to Drip in the First Place

A dripping faucet almost always comes down to a worn internal component. The specific culprit depends on your faucet type. Ball faucets fail at the springs and seats. Cartridge faucets wear out the cartridge. Ceramic disc faucets crack or corrode their discs. Compression faucets, the oldest style, wear out rubber washers at the valve seat.

Identifying the type you have before buying parts saves you a wasted trip to the hardware store. Pull the handle and look at the internal mechanism. If you're not sure what you're looking at, the brand name stamped on the faucet body usually leads you to a parts diagram online. The drip location matters too. A drip from the spout points to internal wear. A drip around the base of the handle points to O-ring failure. Water under the sink suggests supply line or connection problems, which is a different job.

Temperature is important as well. If the drip only happens with hot water, the hot-side cartridge or washer is likely the cause of failure. Cold-only drips point to the cold side. Both sides dripping simultaneously, with no pattern, can mean the valve seat is damaged, which is harder to fix without experience.

Stone Mountain, GA

I called at midnight on a Friday and the dispatcher confirmed an appointment window for 8-11AM that same morning. Shaun was great - he arrived early in the time window and got to the job quickly. There was an issue with a specialized part that broke during installation, and he followed through with great communication until the job was totally completed. I’m not knowledgeable about plumbing, but as far as I can tell, the quality of the work looks good. The cost was not cheap, but I am pleased with the service and the quality of work. Make sure to…

At first the online scheduler didn't work, but it was very easy to call and set up an appointment. I liked receiving a text with the plumber's photo saying he was on his way. Jason arrived as scheduled. He provided all estimates in writing up front and was very courteous and professional as he explained the plumbing problems he found. I decided to replace my aging water heater, and he returned with my new water heater and finished installing it that afternoon, even when I needed to be away for a few hours. The hot water temperature is now perfect,…

Jason and Josh did an excellent job fixing our blocked pipes. They were so quick, kind, and efficient. They did amazing, quality work and they were so nice and professional. It was quite a big project, and They took the time to explain what they would be doing every step of the way We are so happy to have working plumbing in our home again and would highly recommend them to anyone!

Sandy Springs, GA

Ryan was very professional and did a great job of unclogging the pipes. He was the second plumber of the day. The first guy didn't unclog the drain and then proceeded to say it would take $8,000 to fix the clog. Insane. I called Mr. Rooter and had the fortunate opportunity to meet Ryan, who, instead of trying to make a big sale, took his time and unclogged the line in less than 10 minutes. He showed me what was going on and even showed me what was going to be needed in the future. This is why I'll always…

John dubose went above and beyond to fix my issue . He placed a clean out valve in the location of the pipe to make it easier to access whenever my pipes get backed up again. He explained everything before proceeding so I understood what he would be doing to fix my backed up pipes and I can tell he defiantly was a Profesional and have been doing this for a long time . He was very patient with me and answered all of my questions . He showed kindness which i appreciated since i was in so much stress…

I am very satisfied with Jason Johnson and the experience with Mr. Rooter in general! I called in the evening and was placed on the emergency wait line for the next day. Jason came shortly before noon and I immediately had a good feeling about him. I showed him the pipe that leaked in the front yard and he patiently listened to me and took an overview. What I really liked was that he showed his knowledge about the whole situation. He didn't just address the leaking pipe but also pointed out the whole system in general and where else…

Jim Mahoney and his team of plumbers consisting of Jason Johnson, Andrew Fitch, and Cameron Funk were exceptional in the service they provided. I had major damage to my home because of plumbing issues from living in an older home. Jim sent his team out and they not only were thorough in fixing my plumbing issues, they educated me about the contributions I was causing that would eventually lead to more unnecessary problems. I would highly recommend any of the plumbers (Jason, Andrew, and Cameron) to anyone that might have plumbing issues in the Atalanta area. They are knowledgeable, courteous,…

I was very pleased with the service from Mr. Rooter. My tech, Jason, was friendly, timely, upfront about pricing, discussed options, and executed the job promptly. I had a water line replaced and the job was performed quickly and professionally with minimal disruption to my landscaping (only grass near the meter). I would highly recommend Mr. Rooter and specifically, Jason J. and his apprentice Cameron F. The boring crew was friendly and timely as well.

Katheryn Smith

Marietta, GA

Mr Rooter sent out a Tech the very next morning. Arrived on time and replaced the pipe. Was very professional and courteous. A few days later there appeared to be a wet spot on outside brick on house. I called Mr Rooter and they sent an inspector out right away. He was very thorough. NO LEAKS, just water trapped in between the walls trying to dry-out. The inspector was also very professional and courteous. I was very pleased from the moment the young lady answered my call to the lady who sent the inspector out. Their professionalism from start to…

Highly recommend and Great people to work with!! Hi ….just a quick review of “Mr Rooter” who came to my home fixing and redoing a very clogged “sewer drain line”. The folks from Mr Rooter , Bryan and John and Taylor and Rod who spent a couple of days dealing with this issue did an amazing and excellent job of explaining and keeping us informed as to the issues and procedures of this problem. They worked their rear ends off and spent countless hours getting everything done. I knew they really cared and took the time needed to make sure…

The Tools You Need Before You Touch Anything Under the Sink

Attempting a faucet repair without the right tools turns a 30-minute job into a multi-hour problem. Here's what you need before you start:

Adjustable wrench and basin wrench
Phillips and flathead screwdrivers
Allen wrench set
Needle-nose pliers
Replacement cartridge or washers matched to your specific faucet model
Plumber's grease
Plumber's tape for threaded connections
A bucket and old towels

The basin wrench is the one most homeowners skip, and it's the one that creates the most problems. Reaching up behind the sink deck to loosen supply line nuts without it is nearly impossible on standard cabinet depths. You can rent one from most hardware stores if you'd rather not buy it.

Before you touch a single connection, shut off the water supply valves under the sink and turn on the faucet to release pressure. Skipping that step means water in your face and a wet cabinet. Cap the drain with a rag so small parts don't disappear.

Repairs That Most Homeowners Can Reasonably Pull Off

Replacing a worn washer in a compression faucet is one of the more manageable home repairs. You remove the handle, unscrew the packing nut, pull the stem, swap the rubber washer at the bottom, and reverse the process. The total parts cost is very low. A cartridge swap on a single-handle faucet is similarly approachable if you can source the exact replacement cartridge for your model.

Tightening a loose handle, replacing a worn aerator, or swapping a supply line are all tasks most handy homeowners can complete without calling a professional plumber. These jobs don't require disturbing sealed connections or working with soldered pipe.

Installing a new faucet on an existing sink, where the shutoff valves and supply lines are already in good shape, is doable if you're comfortable working in a confined space and following manufacturer instructions precisely. Many homeowners complete this successfully. The job gets harder when the old shutoff valves are corroded, the supply lines are stuck, or the sink has non-standard hole spacing.?

When Replacing the Whole Faucet Is Smarter Than Fixing the Old One

Repair stops making economic sense at a certain point. If your faucet is more than 15 to 20 years old, replacement parts may be discontinued or hard to source. Spending an hour tracking down a cartridge for a discontinued faucet, then paying for it, usually costs more than putting the money toward a new unit.

Visible corrosion around the faucet base, chronic dripping despite recent repairs, mineral buildup that's cracked internal components, or a handle that wobbles no matter how many times you've tightened it are all signs that faucet replacement makes more sense than another repair. A new mid-range faucet runs $100 to $300 for most residential applications and comes with a manufacturer's warranty.

Water efficiency is worth factoring in as well. Older faucets can run 2.2 gallons per minute or more. Current WaterSense-certified models cap at 1.5 gallons per minute. For a household that uses the kitchen faucet heavily, the difference adds up on the water bill within the first year. A qualified plumber in Sandy Springs, GA can swap out the old unit and confirm the supply connections and shut-off valves are in good condition at the same time.

How to Know It's Time to Call a Professional Instead

A few specific situations take a faucet repair out of DIY territory. If you shut off the supply valve and water keeps flowing, the valve has failed and needs replacement before faucet work can happen. If you see active corrosion, green or white mineral buildup on the supply line connections, or soft or discolored drywall under the sink, you may have a slow leak that's been running longer than you know.

Faucets connected to older galvanized or corroded copper supply lines need careful handling. Overtightening a fitting on a compromised line can crack it. A licensed plumber has the tools and experience to determine whether those lines can withstand the work before starting.

Any repair that requires soldering, cutting pipe, or moving a drain is the responsibility of professional plumbers. The same applies if you open up the cabinet and find something unexpected, like a shutoff valve that won't close, a drain assembly that's pulling away from the sink basin, or signs of mold on the cabinet floor.
