Water Heater Services for Your Home

Water heater problems can involve the tank, heating components, burner, thermostat, valves, plumbing connections, or fuel supply. The right service depends on the unit’s age, the source of the problem, and the tank’s condition.

  • New water heater installation
  • Water heater repair
  • Water heater replacement
  • Gas water heater service
  • Electric water heater service
  • Thermostat replacement
  • Heating element replacement
  • Burner and ignition repair
  • Pressure relief valve service
  • Leak diagnosis
  • Tank flushing
  • Plumbing connection repair
  • Water heater maintenance

Waldrop also provides tankless water heater services for homeowners considering an on-demand system.

Signs You Need Water Heater Repair

Some water heater problems develop gradually, while others appear without warning. Addressing changes in performance early may help prevent a complete loss of hot water or a larger leak.

Contact a plumber if you notice:

  • Water is not getting hot
  • Hot water runs out faster than usual
  • Water temperature changes during use
  • The unit makes popping or rumbling noises
  • Water collects around the base of the tank
  • Hot water appears rusty or discolored
  • The burner does not remain lit
  • The pilot light repeatedly goes out
  • The relief valve releases water
  • Hot water has an unusual odor
  • The water takes too long to heat
  • Utility use rises without a clear reason

A repair may be possible when the tank is still in good condition and the problem involves a replaceable component.

Water Heater Installation

Installing a water heater requires correct sizing, secure plumbing connections, proper venting for gas equipment, and compliance with current installation requirements.

The installation may involve:

  • Removing the old water heater
  • Reviewing household hot water demand
  • Selecting the correct tank capacity
  • Connecting hot and cold water lines
  • Installing shutoff and relief valves
  • Connecting the gas or electrical supply
  • Updating venting when required
  • Adding or replacing a drain pan
  • Testing the equipment for safe operation
  • Confirming water temperature and recovery

Our plumbers inspect the installation area before work begins. If existing plumbing connections are damaged or outdated, we explain the required updates before installing the new equipment.

Choosing the Right Water Heater Size

A water heater should be large enough to support normal household use without heating more stored water than necessary. Tank capacity is one factor, but recovery rate also affects how quickly the unit can produce more hot water after the tank has been used.

We consider:

  • Number of people in the home
  • Number of bathrooms
  • Typical shower use
  • Bathtub size
  • Laundry habits
  • Dishwasher use
  • Fuel type
  • Available installation space
  • Peak hot water demand

A larger tank is not always the best solution. Proper sizing helps balance hot water availability, energy use, space, and equipment cost.

Gas Water Heater Installation and Repair

Gas water heaters use a burner to heat the water stored inside the tank. They require a suitable gas connection, venting, combustion air, and working safety controls.

Common gas water heater problems include:

  • Pilot light failure
  • Ignition problems
  • Burner issues
  • Gas control valve failure
  • Improper venting
  • Weak or inconsistent heating
  • Soot near the burner area
  • Unusual combustion odors

Gas odors should be treated as a safety concern. Leave the property and contact the gas utility or emergency services from a safe location. Once the area has been declared safe, Waldrop can inspect the plumbing system and provide gas line service when needed.

Electric Water Heater Installation and Repair

Electric water heaters use heating elements inside the tank. A typical unit has an upper and lower element that work with thermostats to maintain the selected temperature.

Common electric water heater problems include:

  • A failed heating element
  • A faulty thermostat
  • Loose electrical connections
  • A tripped safety reset
  • Slow recovery
  • No hot water
  • Water that is only lukewarm

A plumber can test the water heater components and determine whether repair or replacement is appropriate.

Water Heater Repair

Water heater repair may be practical when the tank is structurally sound and the issue involves a valve, thermostat, heating element, burner, or plumbing connection.

Repairs may include:

  • Replacing a heating element
  • Installing a new thermostat
  • Repairing an ignition system
  • Replacing a gas control valve
  • Correcting a leaking connection
  • Replacing a temperature and pressure relief valve
  • Flushing sediment from the tank
  • Repairing damaged supply piping

The age of the unit and the cost of the repair should be considered before work begins. Frequent breakdowns may indicate that replacement will provide a better long-term result.

Water Heater Replacement

Water heater replacement may be recommended when the tank is leaking, the unit requires repeated repairs, or it can no longer meet the household’s needs.

Replacement may be appropriate when:

  • Water leaks from the tank body
  • Corrosion is visible around the tank
  • Repairs are becoming frequent
  • Replacement parts are difficult to obtain
  • The unit no longer provides enough hot water
  • Energy use has increased
  • Sediment buildup has damaged the tank
  • The water heater is near the end of its service life

A leaking tank cannot usually be repaired. The plumber can help you compare replacement models and determine whether a traditional or tankless water heater is better suited to the home.

Why Is My Water Heater Leaking?

The location of the water can help identify the source of a leak. Water may come from a loose connection, a valve, the drain fitting, condensation, or the tank itself.

Possible causes include:

  • Loose inlet or outlet connections
  • A leaking drain valve
  • A failed relief valve
  • Excessive water pressure
  • Internal tank corrosion
  • A cracked tank
  • Condensation near the vent or piping
  • A damaged expansion tank

A small leak can spread into nearby flooring, walls, or stored belongings. Contact Waldrop promptly if water continues collecting around the unit. For a major leak, shut off the water supply when it is safe and request emergency plumbing service.

Why Water Heater Maintenance Matters

Minerals and sediment can settle at the bottom of a tank water heater. This buildup may contribute to noise, reduced efficiency, uneven heating, and early tank wear.

Water heater maintenance may include:

  • Flushing sediment from the tank
  • Inspecting for leaks
  • Checking plumbing connections
  • Testing the relief valve
  • Reviewing burner operation
  • Inspecting venting on gas units
  • Checking heating elements
  • Confirming thermostat operation
  • Looking for corrosion
  • Testing water temperature

Maintenance needs depend on the equipment, water quality, household use, and manufacturer instructions. A water filtration system may help with certain water quality concerns, but it does not replace routine water heater service.

Water Heater Installation Cost Factors

Water heater installation cost depends on the equipment selected and the condition of the existing installation.

Factors that may affect the total cost include:

  • Tank capacity
  • Gas or electric equipment
  • Equipment efficiency
  • Installation location
  • Venting requirements
  • Plumbing modifications
  • Gas line work
  • Removal of the old unit
  • Drain pan or expansion tank installation
  • Permit or inspection requirements
  • Accessibility of the water heater
  • Repairs to damaged connections

Waldrop evaluates the existing system before recommending replacement. Qualifying customers can pre-qualify online for financing before approved work begins.

Our Water Heater Installation Process

Our process begins with an inspection of the current equipment and installation area.

Inspect the Existing Water Heater

The plumber checks the condition of the tank, plumbing connections, valves, venting, and fuel supply.

Review Household Hot Water Needs

We discuss the number of people in the home, fixture use, and any problems with the current unit.

Explain Repair or Replacement Options

If the water heater can be repaired, we explain the recommended work. If replacement is more practical, we review suitable equipment options.

Remove the Old Equipment

When replacement is selected, we disconnect and remove the existing water heater.

Install the New Water Heater

The new unit is positioned, connected, filled, and prepared for operation.

Test the System

We check for leaks, test water temperature, and confirm that the water heater is operating properly.

Review the Completed Work

Before finishing, we explain the basic controls, maintenance needs, and any important operating information.

Rachel helped me schedule several appointments, but keeping them spaced apart in a way that fits my schedule, which was no mean feat. I have lots of things scheduled and she was able to help me schedule them all without overwhelming me. (I can't get a new box to leave other reviews in, so I'll just add all 3 people who helped me and all three rate 5 stars). Josh came to the house to look at the bathroom fixture and gave me three options. He was quick, efficient and very knowledgeable. I hope he's the one who comes to do the work on the day it is scheduled. Then, Charles came to my aid when I found that I wouldn't be here on the day I had scheduled the work to be done. He quickly found an appropriate date and time, and it was a time that fit my schedule perfectly. Please rate all 3 of these technicians FIVE stars. Thank you.
