Water heater fix/replacement

$300

Carlingford, New South Wales

18th Jun 2026

My instant water heater, a Bosch Hydropower has been leaking. It's an old model, and costly to repair, so I'm thinking of replacing the entire unit. The leak comes from the water valve (See identical issue here: houzz.com.au/discussions/6421413). The replacement part costs around $300. I believe the threaded part, behind the two pins of the valve has a missing o ring leading to the leak. I've tried tightening the nut as much as possible, but it doesn't fix the leak. NB:Please let me know in your offer if you wish to complete a minor repair, or swap the entire system entirely.
