Bristol County Water Heater Services
You probably don’t think about your water heater until you step into an unexpectedly cold shower. However, water heaters don’t always suddenly fail for no reason; it’s years of neglect that can cause poor performance, leading to having to take a cold shower because there’s no hot water. Fortunately, most water heaters give clues that they’re not working well, and here’s what to watch for.
- Inconsistent Water Temperature: If the water alternates between hot and cold or never seems to get hot enough, it could be due to a damaged thermostat, sediment buildup, or failing heating elements.
- Strange Noises: Popping, banging, or rumbling sounds from the water heater usually indicate sediment buildup in the tank. As it hardens, it makes the unit work harder, which can lead to irreparable damage.
- Leaks: A leaking tank could be caused by a loose connection or a corroded tank. If the tank is rusting, the only way to fix it is to replace it.
- Discolored or Rusty Water: If your hot water comes out brown or rusty, it could indicate internal corrosion or a rusted anode rod, which is designed to prevent rust.
