Can I Fix a Dripping Faucet Myself? A Houston Homeowner's Guide

A dripping faucet wastes more water than most Houston homeowners expect. One faucet dripping once per second wastes over 3,000 gallons a year. With Houston water rates climbing, that slow drip adds real dollars to your bill every month.

The good news is that most dripping faucets come down to one worn part. Many Houston homeowners fix it themselves in under an hour with basic tools. Whether you can fix a dripping faucet yourself depends on what type of faucet you have and what's causing the drip.

Read through before you pick up a wrench. We cover what causes the drip, how to identify your faucet type, what the repair actually involves, and what it costs — DIY or professional. We also explain what Houston's hard water does to faucet parts and why yours may be wearing out faster than you'd expect.

By the end, you'll know exactly whether to handle this yourself or call a licensed Houston plumber.

Fixing a dripping faucet is manageable for most homeowners when the problem is a worn washer, O-ring, or cartridge. Turn off the supply valves under the sink first — hot and cold. If the drip stops, the fix is inside the faucet, not the supply line.

Your faucet type determines how hard the repair will be:

• Ball faucet — single handle that rotates; worn springs or seats cause the drip
• Cartridge faucet — single or double handle; a worn cartridge is usually the fix
• Compression faucet — two separate handles; a worn rubber washer is the most common cause
• Ceramic disc faucet — single lever with a wide cylindrical body; harder to repair and easier to crack

Cartridge and washer replacements take 30–60 minutes with basic tools. Ceramic disc faucets are the exception — sourcing the right disc and handling it correctly is tricky. A plumber is the smarter call for those.

Houston's hard water speeds up cartridge and washer wear. Drips happen sooner here than in most Texas cities. The USGS explains how hard water minerals build up and wear down plumbing fixtures. If the drip continues after you close the supply valves, the shutoff valve itself may be failing — that requires a licensed plumber, not a DIY fix.

Most dripping faucets trace back to one worn part inside the faucet body. The part that fails depends on your faucet type, how often it's used, and the quality of your water supply.

These are the most common causes:

• Worn washer or seat washer — the most common cause in compression faucets. The rubber washer presses against the valve seat every time you turn the handle. It wears down with use and eventually lets water through.
• Worn cartridge — the most common cause in single-handle and two-handle cartridge faucets. Moen, Delta, and Price Pfister faucets found in Houston homes use cartridges that wear out over time.
• Damaged O-ring — a small rubber ring on the stem that holds the handle in place. When it wears out, water drips from the base of the handle rather than the spout.
• Ceramic disc deterioration — less common, but found in higher-end single-lever faucets. Sediment scoring on the disc surface breaks the seal and causes a slow drip.

Houston's hard water makes all of these wear out faster. Mineral deposits build up on valve seats and degrade rubber parts at a faster rate than in soft-water cities. If your faucet is dripping sooner than you'd expect, the water quality in your area is likely a factor.

For most standard faucets, yes. If the problem is a worn washer, O-ring, or cartridge, this is a repair most Houston homeowners can handle without calling a plumber. The key is knowing your faucet type before you buy any parts.

Here's what you need:

• Adjustable wrench
• Flathead and Phillips screwdriver
• Replacement cartridge or washer kit — available at Home Depot and Lowe's locations across Houston
• Plumber's grease
• Towel and bucket

Start by turning off the hot and cold supply valves under the sink. If the drip stops, the problem is inside the faucet body. That's your green light to proceed. If the drip continues with the valves fully closed, stop — the shutoff valve is failing and needs a plumber before anything else.

Once the water is off, take a photo of the faucet assembly before you remove anything. This makes reassembly easier and helps you identify the right replacement part at the hardware store. Match the cartridge or washer to your faucet brand and model — buying the wrong part is the most common reason a DIY repair stalls.

Ceramic disc faucets are the one exception. The discs are harder to source, easier to crack during removal, and unforgiving if reassembled incorrectly. For those, a licensed plumber is the better call.

Getting the right replacement part starts with knowing exactly what faucet you have. Buy the wrong cartridge or washer and you're back to the hardware store — or stuck with a faucet that's already disassembled.

Here's how to find your faucet brand and model:

• Check under the sink first — look for the original installation paperwork or a sticker on the supply line. Builders and plumbers sometimes leave this behind.
• Look at the faucet body — most major brands stamp or emboss their logo on the faucet body or the base of the handle. Common brands in Houston homes include Moen, Delta, Kohler, American Standard, and Price Pfister.
• Use the manufacturer's website — most brands have a model finder tool. Enter the serial number from the faucet body and it will identify your exact model and the parts you need.
• Bring the old part to the store — if you can't identify the brand, remove the cartridge or washer first. Take it and a photo of the faucet to the hardware store. Most staff can cross-reference the part.

If your Houston home was built before the 1990s — common in neighborhoods like The Heights, Montrose, and Garden Oaks — you may have an older or discontinued faucet model. Parts can be harder to source at retail. A plumber with supplier access can often find the right part faster and complete the repair in a single visit.

A dripping faucet is not usually a plumbing emergency. But it is not harmless either. Most homeowners underestimate how much damage a slow drip causes over time — and how quickly the problem gets worse.

One faucet dripping once per second wastes over 3,000 gallons of water a year. In Houston, where water rates have been rising, that adds a measurable cost to your monthly bill. It's not a number you notice in one statement — but it adds up across a year.

The drip also does physical damage over time:

• Sink and cabinet damage — constant moisture around the drain area and under the cabinet accelerates rust, mold growth, and wood rot. Houston's humidity makes this worse than in drier climates.
• The drip gets worse — worn rubber and cartridges continue to degrade with every use. A slow drip today becomes a faster drip next month.
• Staining — mineral deposits from Houston's hard water leave permanent stains on sinks and fixtures the longer the drip continues.

When a dripping faucet does become urgent: if the water is coming from a supply line, a pipe joint, or a shutoff valve rather than the faucet head itself — that is a different problem. Turn off your main water supply and call a plumber. Those leaks can escalate fast and cause serious water damage inside your walls or cabinets.
