Water Heater Repair, Installation & Replacement in Katy, TX

When your water heater fails, everything stops — no hot showers, no clean dishes, no laundry. The Katy Plumbing Company has been repairing, installing, and replacing water heaters for Katy homes and businesses for 25 years. Whether you need a same-day repair on a leaking tank or a full upgrade to a tankless system, our licensed plumbers (MPL #36673) handle it start to finish.

Water Heater Repair

Most water heater problems don’t require a full replacement. Our technicians diagnose the issue on-site and carry common repair parts on our trucks for same-visit fixes:

• No Hot Water: Could be a failed thermostat, heating element (electric), or pilot light/thermocouple issue (gas). We test and replace the faulty component.
• Leaking Tank: A leak from the T&P relief valve often means excessive pressure or a faulty valve — repairable. A leak from the tank bottom usually means internal corrosion and replacement is needed.
• Rusty or Discolored Water: A deteriorating anode rod lets the tank corrode from inside. Replacing the anode rod early can add years to your water heater’s life.
• Strange Noises (Popping, Rumbling): Sediment buildup at the bottom of the tank hardens and causes banging sounds during heating cycles. A full tank flush resolves this.
• Inconsistent Temperature: A failing dip tube can mix cold water into the hot supply. We replace dip tubes and recalibrate thermostats.
• Slow Recovery Time: If your water heater takes too long to reheat, the heating element or gas burner may be underperforming.

Water Heater Installation & Replacement

When repair costs exceed 50% of the replacement price — or your unit is over 10-12 years old — a new water heater is the smarter investment. We install all major types:

• Traditional Tank Water Heaters (Gas & Electric): The most common type in Katy homes. We size the tank correctly for your household (40, 50, or 75 gallon) and ensure code-compliant installation including expansion tanks where required.
• Tankless Water Heaters: Endless hot water on demand with 20-30% energy savings over tank units. Ideal for larger families or homes where space is limited. We install Rinnai, Navien, Noritz, and Rheem tankless systems.
• Hybrid Heat Pump Water Heaters: The most energy-efficient option available — uses heat from surrounding air to warm water. Best suited for garage installations in Katy’s warm climate.

Every installation includes proper disconnection and disposal of your old unit, new supply line connections, code-compliant venting (gas units), and a post-install test to verify temperature, pressure, and flow.

Tank vs. Tankless: Which Is Right for Your Katy Home?

Not sure which option fits your situation? We’ll assess your household size, hot water demand, gas/electric availability, and budget to recommend the right system — with no pressure to upsell.

Signs Your Water Heater Needs Attention

• Water temperature fluctuates or never gets fully hot
• Visible rust or corrosion on the tank or connections
• Puddles or moisture around the base of the unit
• Popping, banging, or rumbling noises during heating
• Hot water runs out faster than it used to
• Your unit is over 10 years old and has never been serviced
• Your energy bills have increased without explanation

If you notice any of these signs, call us for a diagnostic. Catching problems early often means a simple repair instead of an emergency replacement.
