Common Plumbing Repairs and What They Cost in 2026

Plumbing costs vary enormously depending on the type of repair, regional labor rates, the age and condition of existing pipes, and how accessible the problem is. Understanding the typical cost ranges for common plumbing repairs helps you evaluate estimates and avoid being overcharged — or underpaying for shoddy work that will need to be redone.

Faucet and fixture repairs are among the most common plumbing calls. Replacing a faucet costs $150–$350 in labor plus parts, depending on how accessible the shutoff valves are and whether any corrosion complicates removal. Toilet repair (flapper, fill valve, or handle) runs $100–$200. Full toilet replacement typically costs $300–$600 including the fixture. Garbage disposal replacement runs $200–$450 including the unit. These are quick, predictable jobs that most licensed plumbers handle at a flat rate.

Water heater replacement is one of the largest routine plumbing expenses. A 40–50 gallon conventional gas water heater installed runs $900–$1,500. Electric water heaters are similar in cost. High-efficiency tankless (on-demand) water heaters cost more upfront — $1,500–$3,500 installed — but qualify for federal tax credits and can reduce hot water energy costs by 20–30%. Hybrid heat pump water heaters are the most efficient option and carry a $300 federal tax credit as of 2026.

Drain and sewer line issues range from simple to expensive. Professional drain cleaning (snaking a clogged drain) costs $150–$300. Hydrojetting for stubborn grease buildup costs $300–$600. Camera inspection of a sewer line runs $200–$400. Sewer line repair for a section of damaged pipe costs $1,500–$5,000 depending on access. Full sewer line replacement (trenchless or open cut) is the largest common plumbing job, running $4,000–$15,000 for a typical residential connection.

Leak detection and repair costs depend heavily on where the leak is. A simple supply line leak at a shutoff valve costs $100–$250 to repair. A pinhole leak inside a wall requires opening the wall, finding the leak, cutting out damaged pipe, and patching — typically $300–$800 depending on access and the extent of damage. If water damage to wall materials has occurred, that adds to total costs. Use the localto.co directory to find verified plumbers near you for accurate, in-person estimates on any of these repairs.

Frequently Asked Questions

How much does it cost to replace all the plumbing in a house?

Whole-house repiping typically costs $4,000–$15,000 for a single-family home, depending on the home's size, the number of fixtures, the pipe material being used (copper vs. PEX), and the difficulty of access. PEX repiping is generally faster and less expensive than copper. Homes with slab foundations are significantly more expensive to repipe than those with crawl spaces or basements.

Why is my water bill suddenly higher?

A sudden increase in your water bill usually indicates an undetected leak. Common culprits include a running toilet (can waste 200 gallons per day), a dripping outdoor hose bib, a slab leak (water leaking from pipes embedded in the concrete foundation), or an irrigation system leak. A plumber can perform a leak detection test to identify the source.

How long does a water heater last?

Conventional tank water heaters last 8–12 years on average. Tankless water heaters last 20+ years with proper maintenance. You can find the manufacture date on the serial number label — most manufacturers encode the year and month in the first few characters. Annual anode rod inspection and occasional flushing to remove sediment can extend tank water heater life.

What is a slab leak and how serious is it?

A slab leak occurs when a water supply or drain line embedded in your concrete foundation develops a crack or corrosion leak. Symptoms include unexplained wet spots on floors, cracked flooring, warm spots on tile floors (hot water line leak), mold smell, or a water meter that keeps moving when all fixtures are off. Slab leaks should be addressed promptly — they can erode the foundation, cause mold, and significantly increase water bills.
