No hot water shouldn't ruin your day. We diagnose quickly and restore hot water fast — often the same day.
You wake up to no hot water. Your first thought isn't "I should call a plumber." Your first thought is "This day just got worse."
Water heater problems cascade. No hot water for a shower. No hot water for laundry. No hot water for dishes. It's a ripple effect through your whole home. Most families can tolerate it for a day. Two days, and people get frustrated. Three days, and you're paying someone to fix it whether you're ready or not.
At Full Cesspool, we diagnose quickly, explain your real options (repair vs. replace), and get you hot water back. If repair works, we'll tell you. If replacement is the answer, we'll explain why and get you back up the same day, typically.
Most water heater problems have quick fixes: a failed thermostat, sediment buildup, a broken heating element. We diagnose these fast and repair them, often the same day. Repairs extend your heater's life by 2–4 years in many cases.
Whether you need a traditional tank heater, an electric unit, or a tankless system, we handle the full installation: sizing for your home, managing connections, venting, permitting, and testing. We explain the trade-offs between tank and tankless so you choose what fits your life and budget.
Tankless systems are efficient and space-saving, but they require specific maintenance and expertise. We service Navien, Rinnai, Rheem, and other leading brands with precision.
Annual flushing, anode rod inspection, and sediment removal keep your heater running longer and more efficiently. We bundle this as a preventative service—far cheaper than an emergency replacement.
Modern plumbing requires expansion tanks to manage water pressure. If your system lacks one, we install it properly. It's a small detail that prevents tank damage and premature failure.
You notice a slow drip from the tank bottom. "It's probably nothing," you think. Reality: That drip is corrosion. It will spread. A $400 repair right now becomes a $1,400 emergency replacement in three weeks.
The water looks rusty when you turn on the tap. The smell is off. Now the tank's integrity is compromised. Repairs are no longer viable. You're looking at replacement.
The tank finally gives. You have no hot water, your utility closet is flooded, and now there's potential damage to your walls, flooring, and anything stored nearby. You're not just paying for a new heater—you're paying for water damage restoration.
This progression takes weeks, but most homeowners in Sullivan, MO don't act until Stage 3. By then, the cost has tripled, and the stress is real.
You describe the problem: no hot water, inconsistent temperature, leaking, rust. We ask follow-up questions to understand the age and behavior of your unit.
We come to your home, inspect the heater physically, check connections, test temperature output, and assess the tank's condition. This takes 30–45 minutes.
We present your options: repair (cost and expected lifespan), replacement (cost of new unit, installation timeline), or tankless upgrade (if relevant). You choose based on your situation, not our preference.
For most repairs, we complete the work the same day. For replacements, we schedule installation usually within 24–48 hours. You're never waiting a week with no hot water.
Before we leave, the heater is tested, you receive documentation of the work, and we explain any maintenance steps for your new system.
Fair concern. Here's our standard: If repair costs more than 50% of replacement cost and your heater is over 10 years old, replacement usually makes more sense. If your heater is under 8 years and repair costs less than 30% of replacement, repair is smart. We give you this framework, not a sales pitch.
Tankless has real benefits (endless hot water, smaller footprint, lower energy use over time) and real trade-offs (higher upfront cost, requires specific maintenance, temperamental in cold climates like Sullivan, MO). We only recommend tankless if your home and habits actually benefit from it.
You'll save $300–$500 on the unit. You'll pay more in labor, and you'll lose the warranty because the DIY installation wasn't certified. Plus, improper installation voids most manufacturer warranties. We handle everything so you're protected.
Most repairs take 1–2 hours. If parts are needed, we often have them in stock and can complete the same day. Complex repairs might take 3–4 hours, but we communicate the timeline upfront.
Tank heaters heat and store water (traditional but less efficient long-term). Tankless heats on demand (more efficient, endless hot water, but higher upfront cost and requires annual maintenance). We'll discuss which fits your Sullivan home best.
Yes. Annual descaling prevents mineral buildup and keeps tankless systems running efficiently. We service all major brands and include this in our maintenance programs.
Rust means the protective lining inside the tank is failing. This typically happens after 8–12 years, depending on water quality in Sullivan. Once rust appears, the tank's lifespan is limited. Replacement is usually the right move.
Yes, in Sullivan. We handle permit coordination and ensure your new installation meets code. This protects you and your home's resale value.

"They explained tankless honestly." — Kevin D., Sullivan
"We were considering tankless for the 'upgrade factor,' but the technician walked us through the real costs and maintenance. Turned out tank replacement made more sense for our household. I appreciated the honesty—they didn't push the fancier option."
