Frequently Asked Questions About Water Heater Repair in Potosi, MO

The T&P relief valve opens to release excess pressure or heat. Leaking can indicate excessive municipal water pressure (above 80 PSI), thermal expansion from a closed plumbing loop, or a defective valve seat that needs replacement.
The anode rod is a magnesium or aluminum core inside the tank that attracts corrosive minerals, sacrificing itself to prevent the steel tank from rusting. It should be inspected every 2 to 3 years and replaced when more than 50% depleted.
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.
A hissing sound in gas heaters often occurs when condensation drips onto the hot burner assembly. Whistling usually indicates restricted water flow through a valve or excessive internal pressure escaping past a safety seal.
A typical family of 4 to 5 requires a 50-gallon gas water heater or a 55 to 80-gallon electric tank (or a tankless unit producing 7.5 to 9.5 gallons per minute) to ensure sufficient first-hour hot water capacity.
