A hot water system is a basic requirement in any household. The hot water system provides clean and safe hot water to be used in bathing, cleaning, and cooking among other things. It is essential to have a well-functioning and properly maintained unit at home, whether it be electric, solar gas or heat pump water heaters. You rarely think about the hot water system, but you quickly notice when it is faulty and all you have is cold water. 

A hot water system can seem complicated, but we have made it easy for you to apply some useful observation tips to maintain your system. We have listed four hot water system maintenance tips for you to follow.  

Please note that any work should be conducted by licensed hot water specialists. Monitoring and checking can be fine, but attempts as self repair can be dangerous and void warranties. The Andrew Vanny Plumbing team are the hot water specialists of the Hornsby area. 

  1. Monitor the TPR (temperature pressure relief) valves

A TPR Valve is what stops your hot water system from over pressurising. The pressure needs to be regulated. Too much pressure can cause problems. Too much pressure over time, can cause leaks or in really extreme cases blow up the tank. Mythbusters have proven this! (Embed video into article) https://youtu.be/jbreKn4PoAc. If there is a leak, or the valve is faulty or you go beyond your service date of every 3-5 years, a host of major problems can follow, so it is important to have a licensed plumber check and replace. You can keep an eye out for warning signs, but replacement should be left to professionals. Diagnosing problems early is a fantastic way to prevent further damage. 

  1. Understand the sacrificial anode rod

The sacrificial anode rod is a metal rod made up of magnesium or zinc that is attached to the tank of the hot water system. Corrosion or rust is the result of electrolytic action which travels through the water and reacts with the surface of the metal at risk. It is called a “sacrificial” anode rod because it sacrifices itself to save the cylinder by attracting electrolytes more strongly than the rest of the hot water system, keeping other system components out of harm’s way. This helps prolong the whole system’s lifespan. Make sure to check on the condition of the rod at least once every 12 months and replace every 3-5 years. If it’s beginning to wear, or you know it hasn’t been checked in a while, get a licensed plumber to check and potentially replace the anode for you. 

  1. Drain the tank

With the help of a licensed plumber, draining the tank is a good practice to ensure that the hot water system is still in good shape and the quality of water being supplied to your home is clean. By draining the tank, you can ensure that there are no sediments lying at the bottom, which can affect the hot water system’s condition and the quality of the water in the tank. Getting a service every 3-5 years as recommended will alleviate this issue. 

  1. Book regular maintenance with a hot water specialist

Most importantly, do not forget to have an annual maintenance check-up with your local hot water specialist. Having a regular check-up will ensure that your hot water system can continue to function well and minimise any issues that may arise in the future. Major problems within a hot water system can be quite dangerous because it deals with heat, so always let an experienced plumber handle this.
