Plumbing Maintenance FAQ
How often should I flush my water heater?
Flush your water heater once a year to remove sediment. In hard water areas, flush every 6 months. This extends tank life and improves heating efficiency.
What causes low water pressure?
Common causes include clogged aerators, partially closed shut-off valves, pipe corrosion, or municipal supply issues. Check aerators first—they're easy to clean.
How do I prevent frozen pipes?
Insulate exposed pipes, seal air leaks near pipes, let faucets drip during freezing weather, and keep cabinet doors open to allow warm air circulation.
When should I replace supply lines?
Replace rubber supply lines every 5 years, braided stainless lines every 10 years. Check for bulges, cracks, or corrosion at connections.
How do I know if I have a hidden leak?
Watch for unexplained water bill increases, musty smells, water stains, or mold. You can also check the water meter while all fixtures are off—if it moves, you have a leak.
