What are expert tips for faucet repair vs replace?

Know your faucet brand and model before the cartridge fails. Having the right replacement part on hand turns a drip into a 15-minute fix. Lifetime warranty cartridges (Moen, Delta) are free -- you just need to contact the manufacturer. They'll ship a replacement at no charge. A faucet that drips only from the hot side usually just needs a hot-side cartridge or O-ring, not a full replacement. Take the old cartridge to the hardware store to match it exactly. Cartridges look similar but are not interchangeable between brands.

What mistakes should I avoid with faucet repair vs replace?

Calling a plumber for a cartridge replacement. This is a basic DIY fix that saves $150+ in labor. Replacing a 5-year-old Moen or Delta faucet instead of using the free lifetime cartridge warranty. Buying a no-name replacement faucet instead of repairing a quality one. A $100 replacement may be worse than the faucet you already have. Ignoring a slow drip because it seems minor. 3,000 gallons per year is $30-$60 on your water bill.

Faucet Repair vs Replace | The Plumbing Directory

Overview

A dripping faucet wastes 3,000+ gallons per year. Fixing it is usually a $10-$30 cartridge swap. But at some point, repeated repairs on an aging faucet cost more than a new one -- and a new faucet also means better performance, a fresh warranty, and an updated look. Here's how to decide.

Cost Breakdown

Always Worth Repairing

Cartridge replacement: $10-$30 parts, 15-30 minutes. O-ring replacement: $3-$5 parts, 15 minutes. Aerator cleaning or replacement: $3-$8, 2 minutes. Handle tightening: $0, 1 minute. These fixes address the most common faucet problems and cost almost nothing. If your faucet is less than 10 years old and from a reputable brand, repair first.

Borderline Repairs

Valve seat replacement or resurfacing: $15-$30 DIY, $100-$150 pro. Spout O-ring replacement on pull-out/pull-down models: $5-$15 parts but can be fiddly. Replacing a broken handle or trim: $20-$50 if parts are available. These are worth doing on a mid-range or premium faucet. On a budget faucet, the parts may cost more than a new faucet.

Replace When...

The faucet is corroding or pitting at the base. Parts are discontinued or unavailable. You've replaced the cartridge more than twice. The faucet body is cracked or damaged. Water leaks from the body itself (not from a fitting). The finish is worn through to bare metal. The faucet is over 15 years old and starting to have issues.

The Real Math

A new mid-range kitchen faucet: $150-$250. A plumber visit to diagnose and repair: $150-$250 (service call + labor). If the repair cost approaches or exceeds the replacement cost, always replace. You get a new warranty, new finish, and zero risk of the next failure.

When to Call a Pro

If the faucet body is leaking (not a fitting or cartridge issue), the internal passages may be corroded. A plumber can confirm whether repair is viable or replacement is needed.

Bottom Line

Repair if it's a cartridge, O-ring, or aerator issue on a decent faucet. Replace if parts aren't available, the body is damaged, or repair costs approach the price of a new mid-range faucet.
