When the hot water goes out in a Katy or Houston home, you need a plumber who answers the phone and shows up the same day. Obsta Plumbing has been installing and repairing water heaters across the Houston area for over 15 years and we stock the most common parts on our trucks so most repairs are finished in a single visit.
We service every major brand of tank and tankless water heater Rheem, Bradley White, A.O. Smith, Rinnai, Navien, Noritz and more. Our licensed Texas Master Plumbers handle gas, electric and hybrid heat-pump units, and every install is permitted and inspected so it meets City of Katy and City of Houston code.
Not sure whether to repair or replace? We'll diagnose the unit, explain your options in plain English, and give you a flat-rate quote before any work starts. Most repairs on units under 8 years old are worth doing; older units often pay for themselves quickly when replaced with a high-efficiency tankless system.

Frequently asked questions
How much does it cost to replace a water heater in Katy, TX?+
Standard 40-50 gallon gas or electric tank replacements typically run between $1,500 and $2,800 installed, depending on the brand, venting, code upgrades and disposal of the old unit. Tankless conversions usually run $3,500-$6,000 depending on gas line and venting work. We quote every job upfront before starting.
How long do water heaters last in the Houston area?+
Tank water heaters in our area typically last 8-12 years. Tankless units last 18-22 years when properly descaled. Hard Katy water shortens both lifespans without annual maintenance, which is why we recommend a yearly flush.
Tank or tankless which is better for my Katy home?+
Tankless is the better long-term value for most Katy and Houston homes you get endless hot water, save 25-40% on water-heating energy, and the unit lasts roughly twice as long. Tank heaters still make sense when budget is tight or the existing gas line and venting can't easily support a tankless upgrade. We'll walk you through both options.
Do you offer same-day water heater installation?+
Yes. Most standard tank-for-tank replacements can be completed the same day you call, often within a few hours. Tankless conversions usually need a day for gas line and venting work.
Should I repair or replace my water heater?+
If your tank is under 8 years old and the repair is a single component (thermostat, element, gas valve), repair is usually the better choice. If the tank itself is leaking, or the unit is 10+ years old and needs a major repair, replacement almost always pays for itself in efficiency and reliability.
