The 5 Immediate Emergency Steps (Act Within 5 Minutes)
If your water heater is actively bursting or flooding your Idaho Falls basement, follow this exact step-by-step sequence:
Step 1: Eliminate Electrical and Electrocution Hazards
Water conducts electricity. If standing water has reached electrical cords, baseboard heaters, floor outlets, or the bottom of an electric water heater, DO NOT step into the water.
- Go to your main electrical service panel (if accessible safely without walking through water).
- Switch off the dedicated double-pole 240V breaker labeled "Water Heater."
- If water is deep or near the panel, shut off the main electrical breaker or call Idaho Falls Power / Rocky Mountain Power for emergency disconnect.
Step 2: Shut Off the Water Supply Immediately
Stopping the flow of incoming water is your highest priority to halt active flooding:
- Local Shutoff Valve: Locate the cold water pipe entering the top of the water heater. Look for a shutoff valve. If it is a round wheel handle (gate valve), turn it clockwise until tightly closed. If it is a lever handle (ball valve), turn it 90 degrees perpendicular to the pipe.
- Main Whole-Home Shutoff: If the valve on top of the heater is rusted, seized, leaking, or inaccessible due to scalding water, go immediately to your home's main water shutoff valve (typically located in the basement near the front foundation wall where the water meter enters, or in an interior utility closet). Turn the main valve fully off to cut all water to the house.
Step 3: Shut Off the Fuel Source (Gas or Propane)
Preventing burner activation on an empty or leaking tank prevents fire and combustion hazards:
- Locate the gas control valve on the lower front face of the water heater. Turn the dial to the "OFF" position.
- Locate the yellow or black manual gas shutoff valve on the gas pipe feeding the heater. Turn the lever 90 degrees so it is perpendicular to the pipe.
Step 4: Relieve Pressure and Drain Remaining Tank Water
Even with the incoming water shut off, 40 to 50 gallons of water remain trapped inside the damaged tank vessel:
- Attach a standard garden hose to the brass or plastic drain valve at the base of the tank.
- Run the opposite end of the hose to a basement floor drain, a sump pit, or outside to a driveway.
- Open the drain valve using a flathead screwdriver or wrench.
- Open a hot water faucet on an upper floor (e.g., in a second-floor bathroom). This allows air into the plumbing lines, breaking the vacuum and allowing the tank to drain quickly.
Step 5: Call for 24/7 Emergency Plumbing Dispatch
Once the flow of water is stopped and the fuel is safe, call Idaho Falls Water Heater Pros at (208) 218-2108. Our on-call technicians maintain fully stocked mobile trucks ready to deploy across Bonneville County day or night.

| Priority 1: Safety | Shut off 240V breaker / cut power | Main Electrical Panel | None (hand switch) |
| Priority 2: Water Stop | Turn off cold water valve or main shutoff | Top of heater or front basement wall | Pliers if handle is stiff |
| Priority 3: Fire Safety | Turn gas control valve to "OFF" | Front lower face of water heater | None (turn dial) |
| Priority 4: Evacuation | Attach garden hose & drain tank | Bottom drain valve to floor drain | Garden hose & screwdriver |
| Priority 5: Dispatch | Call professional emergency plumber | (208) 218-2108 | Phone |
Mitigating Water Damage While Waiting for the Plumber
Water begins damaging building materials within minutes. Mold spores can germinate on damp drywall and carpet padding in as little as 24 to 48 hours. While awaiting our technician’s arrival:
- Extract Standing Water: Use a wet/dry shop vacuum to extract pooling water from concrete floors and carpeted areas.
- Lift Baseboards and Furniture: Elevate furniture onto wood blocks or aluminum foil to prevent wood staining. Remove wet rugs and boxes from the area.
- Promote High Airflow: Set up box fans and a dehumidifier to circulate air continuously across wet surfaces.
- Document for Insurance: Take clear, timestamped photos and videos of the leaking water heater, the serial number label, water levels on walls, and all damaged personal property before cleanup begins.
Same-Day Emergency Replacement in Idaho Falls
When a water heater breaches its internal steel cylinder, it cannot be patched or repaired. Idaho Falls Water Heater Pros carries top-rated Bradford White and Rheem natural gas and electric water heaters in standard 40, 50, and 75-gallon capacities.
Our emergency crew will pump out any remaining water, haul away the ruptured tank, install a brand new code-compliant system with an expansion tank, and have hot water restored to your home in just a few hours.

Proactive Maintenance Protocols for Bonneville County Homeowners
Given the unique environmental stresses of Eastern Idaho—including 14.1 GPG dissolved calcium carbonate from the Eastern Snake River Plain Aquifer, winter groundwater temperatures dropping to 38°F, and severe seasonal freeze-thaw cycles—relying solely on reactive emergency repairs is costly and disruptive. Implementing a structured preventive maintenance routine protects your investment, maintains manufacturer warranty compliance, and preserves peak energy efficiency.
Our licensed service team recommends the following seasonal schedule for all residential and commercial water heating systems in Idaho Falls and Ammon:
- Every 6 Months: Visual and Operational Inspection: Inspect the cold water inlet and hot water outlet connections for green oxidation or white crusting (dielectric corrosion). Check the temperature and pressure (T&P) relief valve discharge pipe to verify there is no active dripping or dried mineral trails. Examine the burner viewing glass on gas units to ensure a crisp blue flame without yellow tipping or soot buildup.
- Every 12 Months: Pressurized Hydro-Flush and Descaling: Connect a high-temperature drain hose to the lower drain valve and evacuate accumulated calcium gravel from the tank floor. For tankless systems, isolate the heat exchanger using service valves and circulate a food-grade virgin citric acid solution for 60 to 90 minutes to dissolve microscopic scale adhering to heat exchanger tubes.
- Every 2 Years: Sacrificial Anode Rod Evaluation: Unthread the top anode rod bolt using a 1-1/16-inch socket and inspect the core wire. If more than six inches of the steel center wire is exposed, or if the rod diameter has diminished below 1/4 inch, replace the rod immediately with a new magnesium rod or upgrade to a powered titanium anode.
- Every 3 to 5 Years: Thermal Expansion Tank and Pressure Regulation Audit: Test your home’s baseline static water pressure using a calibrated digital pressure gauge. If municipal pressure exceeds 75 PSI, recalibrate or replace the pressure reducing valve (PRV). Test the air Schrader valve on the thermal expansion tank to verify that the internal rubber bladder has not torn or waterlogged.
By following this preventive maintenance framework, Idaho Falls property owners can easily extend the service life of their water heaters from the regional average of 8 years up to 12 to 15 years, saving thousands of dollars in premature replacement expenses while enjoying consistent, scalding-safe hot water every day of the year.
