Step 5: Turn on a hot water faucet Open the hot water tap, like a sink faucet, that is nearest to the water heater. This helps to alleviate pressure and allows the tank to drain quicker. If possible, the DIY Network recommends using a tap that is on the floor above the water heater.
The fastest way to drain your hot water heater is to use a small section of garden hose that has a fitting that connects to your drain valve. It's usually the same one used for the bib. You'll need to direct the water flow from the hose into a floor drain, bucket, or safe outside area.
The water heater has a manual valve towards the bottom of the water heater. If you don't turn off the cold water valve, the tank will never empty. Assuming you shut off the inlet cold water valve, you then are able to start draining the water heater. You will find that the water will typically drain pretty slow.
All you need to do is switch off the main power. Take a hose and connect it to the opening at the bottom of the water heater. This will ensure a safe passage for the water to move out. Now you can use the hose to drain the water down the sink. This will also flush out the sediments or any debris deposited.
Open a hot water tap nearest to the water heater, preferably on the floor above. This alleviates pressure in the system, allowing the water to drain quickly from the tank, much like removing your finger from the top of a drinking straw filled with liquid.
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.
Turn off the cold-water inlet to the water heater by pulling the lever 90 degrees or rotating the valve counter-clockwise. Open a hot-water faucet at a sink near the water heater to admit air into the tank. Attach a garden hose to the drain valve, typically a white plastic threaded fitting near the bottom of the tank.
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's not always necessary to drain the entire hot water tank. Since sediment and buildup settle on the bottom of the tank, you may drain a few gallons of water at a time until most of the sediment is flushed out.
The pilot setting on gas water heaters can continue to stay on during flushing, but electric models must be completely off. This is because of the heating elements electric water heaters use, which remain submerged. In an empty tank, they may quickly overheat.
In most cases, all you need to do is turn off the power to the system, turn on the cold water supply by opening up the valve, hook up a garden hose to carry the water and sediment away from the tank and then open up the drain valve and the pressure relief valve.
No, unless you're going on vacation for a month or longer, you shouldn't turn off your water heater. Here's why: You won't see significant energy savings. You'll create more problems by turning your water heater off/on repeatedly.
While draining the tank, keep the pressure relief valve open. This allows air to enter the tank, facilitating a smoother and faster draining process. It also prevents a vacuum from forming inside the tank, keeping the water flowing consistently and preventing potential damage to the tank structure.
It's important to shut off the power to your water heater before draining it, or you could potentially burn out the heating elements. If you have an electric water heater, shut the power off from your home's electrical panel. The correct fuse or circuit breaker should be labeled as being connected to the water heater.
It only takes about 15 to 30 minutes to completely drain a water heater. A typical 40- to 60-gallon residential tank found in most homes will take no more than 15 minutes. However, larger tanks (80 gallons or more) found in homes with larger families can take longer, usually from 30 to 60 minutes; sometimes more.
Open the hot water tank drain valve. Let the water run out the garden hose. This can take 20 to 60 minutes, depending on how big the tank is. Be careful not to damage or break the drain valve when you open and close it.
Accordingly, when the water heater is not flushed, the built-up sediment hampers the functioning and performance of the heater and also damages the heater and your plumbing system.
Connect a garden hose to the drain valve. Run the end of the garden hose to an exterior location or into a bucket to catch the water and sediment that will be released. Flush the water heater tank briefly while the water pressure is on. Open the drain valve for a few seconds and then close it again.
If neither you nor a professional have flushed your water within the last five years, Water Heaters Now recommends not flushing it yourself.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Install a Water Filter
By reducing sediment, you can enhance the drainage speed and overall efficiency of your water heater. Regular maintenance of the water filter is also essential to ensure it continues to function effectively and prevent issues related to sediment accumulation.
Open up all faucets and run them until they are completely drained of water. If there are no faucets on your water heater, then you can drain it by opening up a hot-water faucet that is located near your water heater (usually in your bathroom).
If you have a decent rate of flow, the heater should drain in about 20 to 30 minutes. If you have been 12 hours, your incoming water is not shut off. Probably the gate valve above the heater needs to be replaced. Replace it with a full flow ball valve.
