Water Heater Repair & Installation

Expert Water Heater & Hot Water Tank Services

A reliable water heater is essential for daily tasks like showering, washing dishes, and laundry. At Dor-Mar, we provide fast, professional water heater repair and installation services to keep your home’s hot water flowing efficiently. Whether your hot water tank needs a repair or you’re considering a new installation, our licensed plumbers are here to help.

 

Signs You Need Water Heater Repair

If your hot water tank isn’t functioning properly, it may be time for a repair. Common signs include:

1. No Hot Water

If your taps are running cold, your water heater’s heating element or gas burner may be failing. We diagnose and fix heating issues to restore your hot water. In some cases, a faulty pilot light or broken thermostat may also be the cause, requiring prompt attention.

2. Inconsistent Water Temperature

Does your water switch from hot to cold unexpectedly? This could be due to a failing thermostat, sediment buildup, or heating element issues. Mineral deposits can build up inside your water heater over time, causing it to struggle with maintaining a consistent temperature.

3. Strange Noises

Loud popping, banging, or rumbling sounds often mean sediment has built up inside your hot water tank, reducing efficiency and lifespan. As sediment settles at the bottom of the tank, it hardens and makes your water heater work harder, potentially leading to premature wear and tear.

4. Water Leaks

If you notice water pooling around your water heater, there could be a leaking valve or a cracked tank that needs immediate attention. A small leak may seem harmless, but it can lead to water damage, mold growth, and increased utility bills if left unaddressed.

5. Rusty or Discolored Water

Rusty water could indicate corrosion inside your hot water tank, signaling the need for repairs or replacement. If rust appears only in hot water, the issue may stem from your water heater’s tank, while rust in both hot and cold water could indicate corroded pipes.

 

Water Heater Installation & Replacement

If your water heater is over 10-15 years old, it may be time for a replacement. We install energy-efficient hot water tanks designed to provide consistent hot water while lowering your energy bills. Upgrading to a modern unit can help reduce energy consumption and increase reliability.

Choosing the Right Water Heater

Our experts help you choose the best hot water tank for your home based on:

  • Household Size & Water Usage Needs – A larger household requires a higher-capacity tank to prevent running out of hot water.
  • Energy Efficiency & Cost Savings – Energy-efficient models can significantly reduce operating costs over time.
  • Fuel Type (Gas, Electric, or Hybrid) – Choosing the right fuel type ensures compatibility with your home’s setup.
  • Available Space for Installation – Some water heaters require specific space requirements to operate efficiently.

Professional Installation Process

We ensure your new water heater installation is done correctly with:

  1. Old Unit Removal – We safely remove and dispose of your old water heater.
  2. New System Setup – We install your hot water tank with expert precision.
  3. Testing & Safety Checks – We verify proper water temperature and system efficiency.
  4. Customer Education – We show you how to operate and maintain your new water heater, including how to flush the tank periodically to prevent sediment buildup.

  • Annual water heater inspections – Catch minor issues before they become major problems.
  • Tank flushing to remove sediment buildup – Improves efficiency and prevents wear on heating elements.
  • Leak detection & safety checks – Ensures your unit is free from leaks and operating safely.

Frequently Asked Questions About Water Heaters

How Long Does a Water Heater Last?

Most traditional water heaters last between 10-15 years, while tankless water heaters can last 20 years or more with proper maintenance. If your unit is reaching the end of its lifespan, it may be time to consider a replacement.

How Often Should I Flush My Water Heater?

We recommend flushing your hot water tank once a year to remove sediment buildup and maintain efficiency. This helps prevent overheating and prolongs the lifespan of your unit.

Should I Repair or Replace My Water Heater?

If your water heater is experiencing frequent breakdowns, is over 10 years old, or has developed a leak, replacement may be the best option. If the issue is minor, such as a faulty thermostat or heating element, a repair may suffice.
