Hot water systems really are amazing. You get one installed, you turn on the hot taps – and you get hot water. But it’s important to understand that it’s human-made technological science – not magic – that makes it all happen. And like all human-made things, a little bit of TLC and regular maintenance is going to be necessary to keep it running and extend its life. So today, we’re going to take a deeper look into whether you should flush a water heater.

Do you think flushing hot water systems are already part of the well-established basic servicing and maintenance routine of most systems on the market? Among some of the prominent other hot water system maintenance tips are:

But do you actually need to do a water heater flush every now and then too? The answer is yes.

That’s because while mains water may look, smell and taste basically pure, it’s really not. And while hot water systems are designed to handle and to some degree filter that water as it passes through, there’s no avoiding that – over time – a problem will slowly emerge. This build-up consists of mineral deposits, other water impurities and contaminants, and run-of-the-mill debris and gunk.

You may already be noticing the effects of this sediment build-up, which will eventually damage the system and permanently affect the way it works:

  • Reduction in water flow?
  • Low hot water pressure?
  • Hot water running out too soon?
  • Visible evidence of sediment or rust?
  • Strange smells (caused by bacteria)?
  • Strange noises (including banging)?

Flushing hot water tank systems may be something plumbers do best, and not just because a professional job will always be more thorough, benefitting from all the right equipment, know-how, training and real-world experience. Another reason is that your hot water system wasn’t exactly cheap, and you have concerns about warranties and home insurance.

But for the super-keen and equally handy among you, it is possible to learn how to flush a hot water system for yourself:

1. Turn off the utilities

Remember, your tank unit is powered by at least two utilities, so make sure the gas, the electricity and the water supply are all disconnected as appropriate before you attempt to flush water heater systems.

2. Drain the water

Now, we need to get rid of all of that water in the tank. You can do that either by opening the system’s drain valve, or simply turning on the hot taps and letting it all out that way. However, try to find something useful for the water rather than just watching it drain away.

3. Restore the utilities

Turn the power and water back on, and the system will re-fill – and marvel at the simplicity, because you now know how to flush hot water systems with a super-easy DIY method.

4. Repeat the process

If your system’s symptoms haven’t gone away, repeat the entire process one, two or even three more times – because with each repeat, a little more sediment will be flushed away.
