Frequently Asked Questions
How much does plumbing repair cost?
Average plumbing repairs cost $3,500. Simple fixes like leaky faucets run $100-$250. Major repairs like sewer line replacement can exceed $5,000. Emergency service typically adds 50-100% to standard rates.
How long do water heaters last?
Traditional tank water heaters last 8-12 years. Tankless units last 15-20 years with proper maintenance. Signs of failure include rusty water, strange noises, leaks, or inconsistent hot water temperature.
Should I repair or replace my water heater?
Replace if unit is 10+ years old, has major leaks, or repairs cost over 50% of replacement. Repair if it's newer, issue is minor (thermostat, heating element), and still under warranty.
What causes low water pressure?
Common causes include clogged aerators, pipe corrosion, water leaks, partially closed shut-off valves, or issues with the municipal supply. Start with simple fixes like cleaning faucet aerators before calling a plumber.
How can I prevent frozen pipes?
Insulate pipes in unheated areas, keep cabinets open during freezes, let faucets drip slightly in extreme cold, maintain indoor temperature above 55°F, and drain outdoor hoses. Frozen pipes can burst and cause extensive water damage.
