FAQs
What should I do immediately if my water heater is overflowing in Loudon?
First, turn off the cold-water supply valve located on the pipe entering the top of the tank to stop more water from entering. Next, shut off the energy source—switch the electric breaker to the OFF position or turn the gas control knob to PILOT. Finally, drain excess water into a floor drain or bucket if possible and call our Loudon emergency plumbing team. Quick action limits water damage and makes the job safer for our technicians when they arrive.
What are the most common reasons a water heater overflows?
An overflowing tank is usually caused by a failed temperature and pressure relief (TPR) valve, a thermostat that is stuck in the ON position, sediment buildup that reduces tank volume, or excessive incoming water pressure. In Loudon’s hard-water environment, mineral deposits can accelerate TPR valve failure and sediment accumulation, making regular maintenance especially important.
Is it dangerous to keep using hot water after I notice overflow?
Yes. Hot water spilling from the TPR valve or drain pan indicates that pressure or temperature inside the tank is above safe limits. Continuing to draw hot water can worsen the pressure buildup, potentially leading to scalding water release or even a tank rupture. Shut down the heater and call an emergency plumber right away.
How fast can your emergency plumbers reach my Loudon home?
We maintain a 24/7 dispatch center within Loudon County and average a 60-minute arrival time for calls inside city limits. Crews are equipped with replacement TPR valves, flex lines, and isolation valves so most overflow situations are contained and repaired on the first visit.
Will my homeowners insurance cover water damage from an overflowing water heater?
Most standard policies cover sudden and accidental water damage, which includes an unexpected water-heater overflow. However, they typically do not cover the repair or replacement of the failed appliance itself. Document the incident with photos, keep receipts for emergency plumbing work, and contact your insurer as soon as possible to start the claim process.
What can I do to prevent my water heater from overflowing in the future?
1. Schedule an annual professional inspection that includes testing the TPR valve and flushing sediment from the tank. 2. Install an expansion tank if your home has a closed plumbing system to absorb thermal expansion. 3. Set the thermostat to 120 °F to avoid excessive heating. 4. Add a pressure-reducing valve if your incoming water pressure exceeds 80 psi. 5. Replace the water heater once it approaches its 10-15-year lifespan to avoid age-related failures.
