Why Water Heater Repair Can’t Wait
A malfunctioning water heater affects more than your comfort—it can disrupt your entire routine. Cold showers, dishes that won’t sanitize, and laundry cycles gone wrong are just the start. Even worse, neglecting an issue could lead to flooding, mold growth, or premature system replacement. If you’ve noticed signs like:
- Inconsistent water temperatures
- Rusty or discolored water
- Rumbling or popping noises
- Water is pooling near the tank
- Rising energy bills without explanation
…it’s time to bring in the pros.
At Warrior Sewer and Drain, we know time matters. Our experienced specialists move swiftly to pinpoint the root cause and deliver long-lasting solutions.
Who We Are
We’re not your average drain company. Warrior Sewer and Drain was built on a foundation of trust, transparency, and old-school grit—powered by modern technology. We’ve proudly served Missouri with a reputation for hard work, expert service, and a true commitment to our customers.
When it comes to water heater issues, our expertise runs deep. From tankless water heater malfunctions to traditional gas or electric tank units, we’ve seen it all—and fixed it all.
Just like we do with our sewer backup services, we approach every repair job with precision, professionalism, and unmatched customer service.
Expert Repairs for Every Water Heater Type
Whether you rely on a high-efficiency tankless unit or a classic 40-gallon gas heater, our team is fully trained to work on all water heater types and models. Our repairs cover:
Tank Water Heaters
Standard storage-tank water heaters are reliable, but when sediment buildup, thermostat failure, or tank corrosion sets in, performance tanks. Our licensed pros can quickly identify and correct the issue—often without replacing the whole unit.
Tankless Water Heaters
Energy-efficient and compact, tankless models can last up to 20 years—but only with expert care. We repair heat exchanger failures, flow sensor issues, and electrical malfunctions using manufacturer-grade parts.
Gas & Electric Models
Whether it’s a failing thermocouple in a gas model or a broken heating element in an electric one, we diagnose issues fast and fix them right the first time.
No matter your setup, we restore performance, extend lifespan, and help you avoid the cost of premature replacement.
Signs You Need Water Heater Repair

- Fluctuating hot water that goes from warm to cold in seconds
- Noisy operation like banging, cracking, or high-pitched squeals
- Rust-tinted water, especially first thing in the morning
- Water pressure drop, often caused by internal blockage
- Higher utility bills despite normal usage
Still not sure? Call Warrior. We’ll inspect your water heater thoroughly and provide a clear, honest recommendation—with no upsell and no pressure.

FAQs
If your water heater isn’t producing hot water, the problem could be a broken heating element, a tripped reset switch, or a faulty thermostat. For gas models, the pilot light or thermocouple could be the issue. Call a pro for an accurate diagnosis.
If your unit is under 10 years old and the tank is in good shape, a repair is often the most cost-effective option. However, if the tank is leaking or your heater is older than 12–15 years, replacement might save you more long term.
Most repairs take less than two hours. Common fixes like replacing thermostats or heating elements can often be done on the spot. More complex jobs might require part orders, but we’ll always give you a clear timeline upfront.
