This short article provides you a list of items to verify for both tank type and tankless water heaters. As Water heater replacement Brea go by means of the measures in checking your heater, if you have the slightest doubt in your potential, get a professional, licensed plumber involved! You are dealing with hot water, all-natural gas, and electrical energy!
Tank Sort Water Heater Maintenance:
Vent (Gas Water Heaters Only)
The vent need to be the similar diameter as the draft diverter on the heater tank.
The vent ought to go frequently “up and out” the ceiling.
Exactly where is passes via the exterior wall, the vent really should be double-walled.
Vent sections really should be screwed collectively with a minimum three screws per section.
Note: Terrible 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 avert the heater from exploding if the water stress or temperature exceeds safe limits.
Pull up the handle on the valve and water should really flow out and stop when you let go of the manage.
The T&P valve has a drain line that really should go down to about 6″ from the floor or be plumbed outside your home.
Note: Water leaking out of a T&P drain line can signal a undesirable T&P valve, high water stress, or a malfunctioning thermal expansion device.
Water Pressure (All Water Heaters)
Water pressure more than 80 pounds per square inch (psi) can harm heaters and your piping. It can also harm plumbing appliances, toilets, and your fixtures.
Note: One particular 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 Control
Inspect the heater temperature handle dial to insure its set at the appropriate water temperature.
The ideal water temperature is 120° Fahrenheit.
Note: Something above 120° Fahrenheit significantly increases scalding risk, energy use, and sediment make-up in the bottom of the heater!
Combustion Chamber (Gas Water Heaters)
Turn the gas valve control 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 manage back to the “on position”.
Note: Black soot in the combustion chamber indicates drafting problems, combustion problems, fume problems, and a fire hazard!
Pedestal Base (Gas Water Heaters)
Make sure the pedestal base the heater rests on is stable and supports the unit.
The common pedestal will retain the bottom of the heater at least 18″ off the floor.
Note: A newer water heater might have a “filtered combustion chamber” that is supposed to resolve the want for a pedestal. Check the owner’s manual for your heater.
Drain Valve
Open the drain valve to insure that mineral sediment, anode sludge, or rust has not clogged your heaters drain.
Drain Overflow Pan
If your heater is on the 2nd floor above living space it need to have a drain pan.
The drain pan should be plumbed to the outside of your house.
Inspect the situation of the drain pan, fittings, and piping to the outdoors.
Corrosive Fumes (Gas Water Heaters & Tankless Water Heaters)
Water heaters draw air in for combustion and the top quality of the air is important.
Corrosive liquids, ammonia, or acids stored close to a heater can lead to corrosive air.
Note: Corrosive air drawn into the burner can prematurely corrode the heater.
Internal Tank Corrosion and Rust-The internal tank of your heater is constructed of steel and glass lined to avoid rust. Sacrificial anode rods are installed in the tank to defend the glass lined internal steel tank from rust. Aluminum/Zinc or magnesium anode rods corrode over time and get employed up via an electrolytic process.
Note: Replacing the anode rod can extend the life of the heater but, ought to be done by a trained, qualified service technician.
Sediment Develop-up-Sediment is produced when hard water is heated. The develop-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 cause the recirculating pump to stick until it burns out. Sediment develop-up on the bottom of gas water heaters encourages noisy operation. The noise is brought on by small amounts of water under the sediment layer turning into steam bubbles, which then collapse violently.
Note: Sediment build-up can minimize the energy efficiency of the heater and void the warranty on some Residential Water Heaters!
Tankless Water Heater Upkeep:
Flushing-Most tankless water heater suppliers suggest flushing the entire unit every single 6 months to 1 year based upon the water high-quality. Reference your manufactures recommendation for flushing. Flushing the unit on a regular basis removes any mineral deposits (usually calcium or lime) that may well have built up inside the boilers. Suppliers propose applying a utility pump to circulate three or 4 gallons of vinegar or a different low-grade acid for 45 minutes to clean out any deposits.
