Has your hot water system stopped working properly? Hot water systems involve both plumbing and electrical work, so you may be wondering whether you need to call a plumber or an electrician to fix the system. This article will provide you with helpful information regarding hot water system repairs

What you should check first

It is important to check the circuit breaker and pressure relief valve first. If your circuit breaker has tripped, check whether you can turn it back on before calling a professional. Test your pressure relief valve to see if you can make water pass through the overflow pipe. If no water flows through, your water tank may just need to be filled up. If you continue to have problems with your thermostat or circuit breaker, contact a qualified person for assistance.

What will an electrician fix?

Electricians will deal with all of the electrical components of the system. If your circuit breaker will not stay on, then an electrician is responsible for fixing this. Also if your water is only slightly warm, the thermostat, heating element, or off-peak switch in your electric hot water system may be the cause of this and will need to be fixed by an electrician.

For solar hot water systems, the booster can also sometimes be the cause of temperature issues. Furthermore, with the massive surge in energy-efficient heat pump installations across Queensland, complex electrical faults on compressor control boards require the expertise of a specialised domestic electrician to accurately diagnose and restore performance.

When will you need to call a plumber?

If you notice a leak or signs of leakage like mould or damp patches, a plumber will be required to fix this problem. Whilst also being capable of causing extensive water damage, leaks can reduce the amount of water flowing through a hot water system, which will impact the output temperature of the water and the water pressure. A damaged pressure valve is also another common cause of a lack of water pressure in a hot water system and must be fixed by a plumber.

When your hot water system is expelling discoloured water, it is a sign that the sacrificial anode has failed and the inner water tank is rusted, meaning the unit may need to be replaced. According to the Queensland Building and Construction Commission (QBCC), hot water system replacements are classified as regulated notifiable work, meaning they must be formally logged by a licensed professional to protect property insurance.

If you are experiencing an issue with low water temperature from your hot water system, the tempering valve may be the cause of this. According to hot water guidelines from energy.gov.au, water must be stored at a minimum of 60°C to halt microbial growth but delivered to taps at a maximum of 50°C to prevent scalding, making accurate valve alignment vital.

In gas hot water systems, low temperatures can be the result of a broken gas heater, which will require a qualified gas fitter to repair.

Damien P from Fallon Solutions was excellent from start to finish. I was running about ten minutes late when he arrived, and he was kind enough to wait for me, which I really appreciated. Once I got there, he came straight in, got down to business and took the time to properly understand the issue. Damien was extremely thorough, checking the meter, switchboards and even getting up into the ceiling to locate the fuses and trace the problem. He clearly explained what the issue was, what would be required to fix it, and organised a quote on site to be sent through to the landlord for approval. He then worked with me to find a suitable date and time to come back and have everything rectified. The whole process was smooth, friendly and professional. Damien was helpful, informative and clearly knows his stuff. I really appreciated the level of care and professionalism and would happily recommend him and Fallon Solutions.
