Blacktown NSW, Australia
5th Jul 2025
Hi, suddenly my new hot water (installed last month )stopped, as cold water is coming through hot water system, and the wiring connected to the hot water system is fried (not sure) the old hot water system was replaced with more powerful one, may be it could be too much for the old wires to work out . May be there is a fuse out as well. Need someone to fix this, may be need to install new wiring or I don’t know needs to be checked by electrician. I have taken pictures of what could be the connection to these hot water system Please provide reasonable pricing, thank you
Check hot water heater
$100
Castle Hill NSW, Australia
4th Jul 2025
Hot water heater runs out of hot water after approximately 2 days. To fix it, I have to switch off the water heater on the electrical switchboard and flush the tank. As you can imagine, it is exhausting to do this every 2nd day. Will need a plumber to come and diagnose issue and fix.


Diego has been most helpful and knowledgeable. Highly recommended!

No hot water coming out of any tap , shower head etc. usually there is at least just cold water but this time there is NO water coming out at all when you switch to hot side on taps. Rest of apartment building has hot water only our apartment. Strata says it could be tempering valve issue.

Replace 125L Rheem electric hot water system
$1,000
Macquarie Park NSW 2113, Australia
10th May 2025
Have been quoted to replace the thermostat & element. if that doesn’t fix it then I’d have to replace the whole system. I think it would be better to replace than repair? Please quote on replacing thermostat an element and a separate quote to replace whole system. a new 125l electric hot water system. Price to supply, fit and remove old system. Location: Macquarie Park. 2113


Stephen was great. He is very thorough. He made sure there was no water leaks before he left. Cleaned up after himself.
