Frequently Asked Questions About Water Heater Repair in Brentwood, MO

An anode rod is a crucial component that attracts corrosive elements in the water. It rusts so your steel tank doesn't have to. You should have it checked every few years and replaced before it completely dissolves.
No, a leaking Temperature and Pressure (T&P) valve means there is either excessive pressure inside the tank, the temperature is dangerously high, or the valve itself has failed. This is a safety issue that should be addressed immediately.
This occurs when you turn off the hot water briefly and turn it back on. You get the hot water already in the pipe, followed by a brief burst of unheated water, then hot water again. Modern units or recirculation pumps can fix this.
Simply call us at (877) 415-0636. Our friendly dispatch team will take down your information and send a certified water heater technician to your home in Brentwood, MO as quickly as possible.
Look for a pipe entering the top of your water heater. There should be a valve on it. If it's a lever-style valve, turn it so it is perpendicular to the pipe. If it's a round knob, turn it clockwise until it stops.
