An important part of your water heater, it moves cold replacement water to the bottom of the tank when you use hot water; otherwise, both will mix and reduce the water temperature. Anode Rod Replacement: While an anode rod costs between $20 and $50, a plumber can replace it for $50 to $150.
Most homeowners should flush their water heaters every 6 months or so, but if you have extremely hard water, you may want to do it more often. Flushing your hot water heater could be necessary as often as every few months depending on the mineral content of your local water supply.
However, most professionals recommend inspecting the anode rod every one to three years and replacing it every four to five years. If your water supply has a high mineral content or if your water heater usage is heavy, these timelines may need to be shortened.

Best Anode Rod for Residential Water Heaters
The choice between aluminum or magnesium anode rods for residential water heaters depends on the local water quality. Magnesium rods are better for areas with soft water, while aluminum rods are ideal for hard water areas.
The frequency of anode rod replacement depends on several factors, such as water quality, usage patterns, and the type of anode rod installed. In most cases, we recommend inspecting and potentially replacing the anode rod every 3 to 5 years.
All water heaters have a minimum of one anode rod. Some water heaters have longer warranties because they have two anode rods. If there are two anode rods, that is because one is attached to a hex head at the top and the other is a combination anode attached to the hot water outlet.
rust-coloured hot water – that smells – is a classic sign of actual, and serious, tank corrosion. With a bit of luck, it's the corroded and rusty anode rod that's discolouring your water and making it stink and taste weird. Either way, you do need to call your friendly local plumber before that tank is completely shot.
Anode rods are usually installed and kept in the heater for several years, so it may be a bit hard to get loose. You can try using a "breaker bar" for better leverage or you can also try tightening the rod just a little to loosen up the threads.
In any case, water heater anode rods are essential for protecting your tank from corrosion, but they eventually wear out after around 3-5 years, depending on many factors including the hardness or softness of your water.
In summary, the main difference between magnesium and aluminum anode rods is that magnesium anode rods are more efficient in soft water and have a shorter lifespan, while aluminum anode rods are more efficient in hard water and have a longer lifespan.
The national average cost to flush a water heater is $160, but prices can vary in increments based on the tank size. A 30-gallon tank will cost between $90 and $120 on average, while a 70-gallon tank could cost anywhere between $180 and $250.
If neither you nor a professional have flushed your water within the last five years, Water Heaters Now recommends not flushing it yourself.
It is recommended that you flush your water heater at least once per year. Doing so will help to prevent the potential problems that sediment can bring over time. Typically, it takes one to two hours to flush a water heater. The size of your tank will impact the amount of time it takes to drain.
Selecting your new anode rod should be based on your water's condition and your budget. For example, to get rid of bacteria causing your water to smell foul, go with a zinc/aluminum or electric anode rod. For the most economical choice, magnesium is the way to go – but be ready to replace it again in a few short years.
The rods can deteriorate in as little as 3 to 5 years, depending on many factors, including the hardness or softness of the water. Without a working anode rod, the water heater tank will be vulnerable to rust, corrosion, and other damaging effects of chemicals and minerals in the water supply.
