Why Replace Your Water Heater?

Over time, water heaters can become inefficient, rusty, or prone to corrosion—leading to poor performance, higher energy bills, and the risk of leaks. You should consider replacing your unit if you’re experiencing:


  • Insufficient hot water or inconsistent temperatures
  • Rusty or discolored water
  • Leaks around the tank or fittings
  • Frequent need for repairs
  • Your system is 10+ years old


Replacing your old water heater can improve comfort, reduce energy costs, and help avoid emergency breakdowns.

At Knight Plumbing LLC, water heater replacement isn’t a one-size-fits-all service. Here’s how we ensure your new system is the right fit and installed correctly:
