Draining a water heater helps flush out this sediment, usually made up of minerals and other debris, that may cause it to malfunction, says HGTV. If you do not properly maintain your water heater, it may not work efficiently or could simply stop working at all.
Shortened Lifespan: A water heater that isn't flushed regularly may experience corrosion and other damage more quickly, leading to a shorter overall lifespan. Water Quality Issues: Sediment can affect the taste and quality of the water, potentially leading to discolored or foul-smelling water.
At least once a year, you should flush your Gas water heater's drain. Draining your water heater is done to remove any hard water or sediment. Collected water will cause bacteria and become disinfected if it is not drained for an extended period of time.
If neither you nor a professional have flushed your water within the last five years, Water Heaters Now recommends not flushing it yourself.
Perform a vinegar soak.
Vinegar is part of clearing and cleaning a clogged drain, and it's also helpful in removing sediment from water heaters. After you've drained your hot water tank, you can pour a gallon or so of vinegar through it.
Expect a pro to charge you between $75 and $200 to come to your home to flush your water heater, depending on where you live. While this cost deters many homeowners from performing this annual maintenance, it can extend the water heater's lifespan by years, making it worth the additional cost.
NOTE: If your water heater has been installed more than five years without any maintenance, it may be too late to flush. If the tank will not drain, sediment likely has built and clogged the drain.
Keep an eye out for debris suddenly showing up in your water. If you notice sediment or any brown sludge coming out of your faucet, that's probably an indication that it's time for a water heater flush. If you see any of these signs, it's a good indication that your water heater needs maintenance.
Water Heater Lifespan
If your tank water heater is more than 10 years old, it may be time to consider replacing it. With proper maintenance, a tank water heater tank should last six to 12 years. A tankless water heater can last for more than 20 years. Check your water heater's warranty for the most accurate timelines.
You can flush your water heater yourself if it's done on a regular basis. This guide will take you through the steps to drain and flush a gas or electric water heater. Learning how to clean a water heater is an essential part of maintaining your plumbing system.
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.
Opening a hot water faucet will help the water heater drain faster. Some drain valves may be opened with a handle but others require a flat blade screwdriver. Let the water heater drain completely.
Draining your hot water tank removes sediment buildup, helping your water heater perform more efficiently, which can save you money. If the tank isn't annually drained, a hot water heater won't last as long, and the water may heat more slowly.
How Long Does It Take to Drain a 50-Gallon Water Heater? Draining a 50-gallon water heater for larger units usually takes 45 to 60 minutes. However, it's worth noting that these are approximations, and the actual time can vary.
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.
Water heaters show several signs of going bad, including lack of hot water, temperature fluctuations, decreased water pressure, strange noises, rotten egg smell, visible leaks, rusty or discolored water, and increased energy bills. If your water heater is over 10 years old, it may be time to consider a replacement.
-Reduced Efficiency: As scaling collects at the bottom of the tank, your water heater will become less effective at heating the water in the tank. -Corrosion: If your water heater goes long enough without a proper flush, you could also have corrosion attacking the tank itself, weakening its structural integrity.
The average U.S. homeowner spends about $160 to flush a water heater. Depending on the type, size, location, and labor, most spend between $110 and $200. Your average water heater flush cost falls around $160, with most prices ranging from $110 to $200 depending on several factors.

Anode rods require routine inspection and replacement, approximately every three to five years. Without proper maintenance, the anode rod loses its ability to divert damaging particulates from your tank and can accelerate rust and corrosion from chemical reactions, excessive heat, and imbalanced pH levels.
Labor Cost to Install Water Heater
In general, plumbers cost $45 to $200 per hour, while electricians cost $50 to $100 per hour. Expect the following average price ranges for labor alone: Replacing a tank-style water heater: $150–$450. Replacing a tankless water heater: $600–$1,850.
To remove that calcium before it can block the tubes, and to improve the heating efficiency of the heater, we need to flush the tankless water heaters about once a year with vinegar. Vinegar is a weak acid which will dissolve the calcium.
