Check hot water heater

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.

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.
