Water Heaters Plumbing Services in Richardson, TX

A standard 40 or 50 gallon tank runs $1,200 to $2,500 installed for gas, or $1,200 to $2,200 for electric. If the venting needs to be brought up to code, or the unit is in an attic with difficult access, expect $2,000 to $3,500. Tankless runs $2,500 to $6,500 installed, and a conversion from a tank often costs more because it needs a larger gas line. Haul-away of the old unit is included.

Shut the valve on the cold line entering the top of the unit, turning it clockwise. That isolates the heater without shutting off the rest of the house. Then shut off the fuel: turn the gas knob to OFF, or shut the breaker for an electric unit. Do this even if the leak looks small, because an electric element firing in an emptying tank burns out in minutes. If the heater is in the attic, move what you can from the rooms below. Then call 214-918-6109.

Yes, and there is something you should do this week. Check that there is a drain pan under it, check that the pan actually has a drain line running to the outside of the house rather than just ending in the attic, and put a $15 battery water alarm in the pan. A 50 gallon tank failing in a garage is a wet floor. The same tank failing in an attic sends fifty gallons through your ceiling. The alarm is the best fifteen dollars in home ownership.

If water is coming from the tank body itself, replace it. A rusted-through tank cannot be repaired, and anyone who says otherwise is selling you time rather than a fix. If it is leaking from a fitting or a valve at the top, that is a repair. If it is 12 or more years old and needs a $400-plus repair, replace it. Under 8 years old, repair almost always wins.

Tank heaters last 8 to 12 years in this area, and hard water shortens that. Tankless lasts 15 to 20 years with annual descaling. If yours is over 10 and it lives in your attic, replace it on your schedule instead of its schedule. Planned replacement is around $1,500. Emergency replacement plus ceiling repair can be $8,000.

For some houses. The honest pitch is not the energy savings, because the payback from efficiency alone takes many years and often does not close. The real reasons are that it cannot flood your house, it lasts twice as long, and you never run out of hot water. The real reason not to is hard water. This area runs 5.4 to 7.8 grains per gallon, which scales a tankless heat exchanger, so it needs annual descaling. Skip that and you will kill a $5,000 appliance in half its life.

Sediment. Minerals settle at the bottom of the tank and water boils underneath the layer, which is the noise you hear. It insulates the burner from the water, makes the heater work harder, and shortens its life. A flush fixes it, and it is a $150 to $250 job or a homeowner job with a garden hose.

Usually sediment buildup taking up tank volume, or a burned-out lower heating element on an electric unit. Both are repairs, not replacements. If your family size grew and the tank did not, that is a sizing problem instead.

Usually not. It is most often the thermocouple, which is a $150 to $300 repair. Do not let anyone talk you into a new water heater over a pilot that will not stay lit until the thermocouple has been ruled out.

It matters more than almost anything else on the appliance. The anode is a sacrificial metal rod that corrodes so the tank does not. When the anode is gone, the tank starts rusting. Replacing a $200 anode rod buys years on the back end of a water heater's life, and almost nobody does it.

Usually yes. A water heater is a gas appliance and a venting appliance, and cities require a permit and inspection. We pull them. Big-box installers often skip it, and it shows up when you sell the house.

No. The 25C program ended in December 2025. If somebody is still quoting you a tax credit on a water heater, their sales pitch is out of date, and it is fair to wonder what else is.

If you call before noon on a weekday, usually yes. Our hours are Monday through Friday, 8:00 AM to 5:00 PM. We are not a 24-hour company. After hours and weekends carry a flat $199 dispatch fee, quoted on the phone before anyone gets in a truck. A leaking tank is one of the few problems that genuinely does not wait, and we will tell you honestly which one you have.
