Just like any other plumbing appliance, a hot water system also requires regular maintenance. And an important part of routine maintenance is flushing the water system’s tanks.
Emptying the tank has a myriad of benefits, such as it prevents the formation of scale and sludge. Also, it helps prolong the life of the hot water system, and you get a reliable supply whenever you need it.
However, flushing a hot water system is not as easy as it sounds. So, we have compiled a list of four easy steps you can follow and do it yourself. There are some safety tips listed as well that’ll help you keep safe while flushing the water tanks.
Why Should I Flush my Hot Water System?
You might be wondering why I should flush the hot water system when it is working fine! Well, there are a myriad of reasons to do it occasionally. The biggest perk of emptying the tank is getting rid of the mineral deposits.
Also, water carries contaminants that get screened inside the hot water tank, so you can eliminate the contaminants by flushing the tank.
Another question is, how often should you flush the tank? There is no specific answer to it because you need to flush it when you encounter the following problems.
- A strange smell in the water
- No hot water
- Low hot water pressure
- Strange sounds like gurgling noises
Hot water tanks don’t have a light that turns on when it requires maintenance. So, you should keep an eye on the following things.
Things You Should Know About the Hot Water System
A hot water system, be it of any brand like Rheem or Dux, has multiple components you should know about. These include the valves and the rods, which you have to check to ensure your system is in perfect condition.
Valve Checks
You should check the valves every now and then since they are outside the tank and do not require dismantling anything. Also, checking the valve helps you identify any leaks, and look for signs that require immediate plumbing help.
Anode Rod
The anode rod is made using metal with a thick coating of sacrificial metal over it. However, over time the rod starts to corrode, and it needs a replacement. When flushing a hot water system, you should inspect the rod to look for any signs of corrosion or damage.
Plumbing Inspections
Inspect other elements of the tank, including the wiring, piping and body. It would be great if you could have a professional on board to get all these things checked.
Steps to Flush a Hot Water System like a Pro
Now you are all set to flush the water from the hot water system. Just follow the below-mentioned steps, and you can empty the tank quickly.
- Turn the Hot Water System and the Water Supply Off
The first step is turning the hot water system off. You need to turn off the electric supply and plug out the wires from the socket. In the case of a gas-powered hot water system, you need to turn the gas supply on.
It is completely ok to leave the pilot light on, just ensure no one inside the house turns on the taps when you are emptying the taps.
The next thing to do is turn the water supply off. This is simply because you have to turn the main supply like a valve off. This valve is common for both electric as well as gas-powered water heaters. - Let the Heater Cool Down and Attach a Hose
The heater will not cool down immediately after you turn off the supply, so you have to wait for some time. On average, the water heater may even take around 60-80 minutes to cool completely. The easiest way to find out if the water is still hot or not is by using the tap.
Once you are sure the water is cool, attach the hose to the water tank’s drain valve. The tank may dispense the water with immense pressure, so place the other end of the hose in the garden or somewhere around a drain. - Turn the Tap and the Drain Valve On
Turn any two water taps on to help the water system get air. It will help you empty the tank quickly. Also, turn the drain valve on, and wait for the tank to get empty. Don’t open the valve fully, as it may even lead to the hose flying out with water.
You’ll hear some gurgling noises from the tank when it is about to get empty. Moreover, the pressure inside the hose will reduce and will come to a halt. - Wrap Up
Turn the drain valve off, and remove the hose. Also, you can now turn the hot water system’s supply on, followed by the main supply line valve. The tank is not 100% sediment-free and is ready to reheat water again.
Final Thoughts
Hot water systems are an important investment. Moreover, they contribute to the overall value of your house, so it is essential to keep them in good shape. Follow these four steps to empty the tank every month or whenever you experience any issues with the water pressure.
