Frequently Asked Questions About Water Heater Installation in St. Ann, MO

Yes. When we install a new water heater at your property in St. Ann, MO, our service includes complete disconnection, safe draining, removal, and eco-friendly metal recycling of your old equipment.
A sulfur odor is usually caused by anaerobic bacteria in your water supply reacting with the tank's magnesium sacrificial anode rod. Our technicians in St. Ann, MO can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
Scheduling is fast and easy. Call our direct field dispatch hotline at (877) 552-4213. Our local coordinators in St. Ann, MO will log your symptoms and dispatch the nearest available technician to your property immediately.
A cold water sandwich happens when hot water left in the pipes is followed by a brief surge of unheated water while the flow sensor triggers the burner. Installing an internal or external recirculating buffer tank eliminates this issue completely.
Condensation is common when a cold tank is filled with water during initial startup. However, continuous dripping beneath the tank after hours of heating indicates an internal tank leak requiring immediate inspection.
