Water Heater Repair in Corpus Christi
Authorized Service for Major Brands, Backed by Nearly 30 Years Here
When your water heater stops working, you need a team that understands the unit in front of them. Custom Filtration & Plumbing Co. is a veteran-owned, family-operated plumbing company serving Corpus Christi and Nueces County since 1996. We hold authorized representative certifications for A.O. Smith, State, Whirlpool, Rheem, Navien, and Rinnai, which means we’re not guessing at your repair. We know these systems, and we carry the credentials to back it up.
Corpus Christi’s coastal environment is hard on water heaters. Salt-laden air near the bay, Flour Bluff, and Padre Island accelerates corrosion on fittings and exterior components. South Texas limestone deposits leave mineral scale on heating elements and inside tanks faster than most people expect. Our team has been diagnosing these region-specific problems for decades, and that local knowledge shapes every repair we make.
If your water heater is failing, don’t wait for it to get worse. Call Custom Filtration & Plumbing Co. today at (361) 240-8466 for same-day service availability and a flat-rate quote before any work begins.A Service Experience Built on Accountability

Signs Your Water Heater Needs Repair
Some symptoms are easy to miss until they become urgent. In Corpus Christi’s hard-water environment, wear accumulates faster than in softer-water regions, so knowing what to watch for matters.
- No hot water or sharply reduced output: The most urgent indicator of a failing unit, often pointing to a burned heating element or failed gas burner assembly.
- Fluctuating water temperature: Typically caused by a failing thermostat or heating element cycling inconsistently.
- Popping, rumbling, or banging sounds: Sediment from mineral deposits settles at the tank bottom and overheats, creating noise and reducing efficiency.
- Rust-tinted or discolored water: Often signals a depleted anode rod and advancing internal tank corrosion.
- Water pooling at the base or around connections: A leak that requires prompt attention to prevent property damage. Salt-air corrosion on external fittings can create slow leaks that go unnoticed until damage is visible.
- Reduced hot water pressure: Scale buildup may be restricting flow inside the tank or supply connections.
Water Heater Repair in Corpus Christi: What We Do
When you call us, we inspect the unit, identify the specific failure point, and explain exactly what the repair involves and what it will cost before we touch anything. That flat-rate quote gives you the information to make a confident decision, including comparing repair cost against replacement if the situation calls for it.
Our repair work covers the full range of water heater components:
- Thermostat and heating element replacement
- Gas valve and burner assembly service
- Anode rod inspection and replacement
- Sediment flushing and tank cleaning
- T&P relief valve inspection and service
- Connection and fitting repairs
We also service tankless water heaters, including descaling and component diagnostics for Navien and Rinnai systems. Durable parts go into every repair, and warranty upgrade options are available for added long-term assurance.
Repair vs. Replace: Getting It Right
As a general guideline, repair is usually the cost-effective path when the unit is under 8 to 10 years old and the failure is isolated to a single component. Once a tank is leaking, the unit is over 10 years old, or repair costs are accumulating, replacement becomes the better investment. In Corpus Christi’s hard-water environment, units often show accelerated wear, so a professional assessment matters. Our flat-rate quote makes the comparison straightforward: you’ll know the repair cost before you commit, and we can give you an honest recommendation either way.
