Signs a tank needs attention
Book the manufacturer first if the tank may be under warranty: warranty repairs are free, but non-warranty work is paid on completion at the call-out rate.
- Water or rust streaks down the side of the tank
- Corrosion around the top fittings or relief valve
- Water pooling at the base, or a constantly dripping relief valve
- Lukewarm water or a tripping circuit breaker
Solar inverters

The inverter is the box on the wall that converts power from the solar panels into mains electricity. Its screen shows whether the system is producing power; a warning light or blank screen during the day is worth checking.
Inverters usually last about 10–15 years, less than the panels. Replacing one typically costs about $1,500–$3,000 installed (estimate), depending on size and brand.
