Frequently Asked Questions About Water Heater Installation in Barnhart, MO

A pilot light that won't stay lit is usually caused by a faulty or carbon-coated thermocouple, a blocked pilot orifice, a defective gas valve magnet, or poor combustion air intake. Call (877) 552-4213 to have a technician test and replace the thermocouple safely.
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 Barnhart, MO can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
Low hot water pressure is typically caused by heavy mineral scale clogging the water heater's hot outlet nipple, a partially closed shut-off valve, or a defective heat trap. Our technicians can clean or replace the fittings to restore full flow.
First, turn off the cold water shut-off valve located on the pipe directly above the water heater. Second, turn off the gas supply or switch off the dedicated electrical breaker. Then immediately call (877) 552-4213 for emergency water heater dispatch in Barnhart, MO.
