Best Faucet Repair Kits – Cartridges, Washers, and O-Rings

Faucet repair kits allow homeowners to fix dripping faucets and restore full function without replacing the entire faucet. A dripping faucet wastes 2,000-3,000 gallons per year. Most faucet repairs cost $5-20 in parts and take 30-60 minutes with the right repair kit.

Types of Faucet Designs and Repair Parts

Compression Faucets (Older Two-Handle)

The oldest faucet design. Uses rubber washers that compress against a seat to stop water flow. Drips when the washer wears out. Repair kits include washers, O-rings, and packing. Most common in homes built before 1980. Easiest type to repair.

Ball Faucets (Single-Handle)

Common in kitchens. A rotating ball with ports controls water flow and temperature. Drips from worn springs, seats, O-rings, or a cracked ball. Ball faucet repair kits include all internal components. Available brand-specific (Delta, Moen) and universal.

Cartridge Faucets (Single or Two-Handle)

The most common modern faucet design. A cartridge controls both flow and temperature. Drips when the cartridge O-rings or cartridge body wears. Replacement is straightforward – pull out the old cartridge, insert the new one. Cartridges are brand and model specific.

Ceramic Disc Faucets

Uses ceramic discs that rarely wear out but can crack or develop debris buildup. Repairs typically involve cleaning or replacing the ceramic disc cartridge. Very long service life before needing repair.

FAQ

How do I identify my faucet brand?

Look for a brand logo on the faucet body – usually on the escutcheon plate at the base. If no logo is visible, search online for the appearance. You can also take the faucet to a plumbing supply store where staff can often identify the brand from the cartridge or part.
