The vent should really go usually “up and out” the ceiling.
Exactly where is passes by way of the exterior wall, the vent should be double-walled.
Vent sections need to be screwed collectively with a minimum three screws per section.
Note: Undesirable vent pipe connections can fall apart and lead to carbon monoxide poisoning, the silent and deadly gas!

Temperature & Stress Relief Valve (T&P Valve)The T&P valve is designed to protect against the heater from exploding if the water pressure or temperature exceeds safe limits.

Pull up the manage on the valve and water really should flow out and cease when you let go of the deal with.
The T&P valve has a drain line that ought to go down to about six” from the floor or be plumbed outside your residence.

Note: Water leaking out of a T&P drain line can signal a poor T&P valve, higher water stress, or a malfunctioning thermal expansion device.

Water Stress (All Water Heaters)

Water pressure over 80 pounds per square inch (psi) can harm heaters and your piping. It can also damage plumbing appliances, toilets, and your fixtures.
Note: One giveaway that your have high water pressure is when the T&P Valve on the heater starts opening and closing.

Outer Water Heater Metal Shell & Plumbing Fittings

Inspect the heater outer sheet metal shell for leaks or rusting.
Inspect the plumbing fittings on the heater for corrosion, rust, or water spotting.
Note: Rusty fittings or discolored shell is a telltale sign that a leak is present!

Temperature Handle

Inspect the heater temperature handle dial to insure its set at the right water temperature.
The perfect water temperature is 120° Fahrenheit.
Note: Anything above 120° Fahrenheit greatly increases scalding danger, energy use, and sediment build-up in the bottom of the heater!

Combustion Chamber (Gas Water Heaters)

Turn the gas valve handle to “pilot position”.
Eliminate the outer access hatch or cover on the side of the heater.
Inspect the roof of the chamber for heavy rusting, water marking, or pitting.
Return the gas valve handle back to the “on position”.
Note: Black soot in the combustion chamber means drafting troubles, combustion problems, fume issues, and a fire hazard!

Pedestal Base (Gas Water Heaters)

Make confident the pedestal base the heater rests on is steady and supports the unit.

Internal Tank Corrosion and Rust-The internal tank of your heater is constructed of steel and glass lined to stop rust. Sacrificial anode rods are installed in the tank to safeguard the glass lined internal steel tank from rust. Aluminum/Zinc or magnesium anode rods corrode over time and get used up through an electrolytic course of action.

Note: Replacing the anode rod can extend the life of the heater but, should be done by a trained, experienced service technician.

Sediment Construct-up-Sediment is designed when tough water is heated. The make-up of sediment in the bottom of the tank can lead to the bottom to overheat and melt away the glass lining of the tank. It can drift into recirculating lines, jam open verify valves, and trigger the recirculating pump to stick till it burns out. Sediment construct-up on the bottom of gas water heaters encourages noisy operation. The noise is triggered by little amounts of water beneath the sediment layer turning into steam bubbles, which then collapse violently.

Note: tankless water heater Riverside CA create-up can reduce the energy efficiency of the heater and void the warranty on some Residential Water Heaters!
