Tools & methods
Tools and Methods We Use for Solar Water Heater Repair
Multimeter
We use a multimeter to test voltage and continuity on thermostats, heating elements, and wiring. It helps us pinpoint electrical faults fast.
Thermostat Tester
This tool verifies thermostat calibration and operation. We use it to confirm whether a thermostat is sending the right signals to the heating element.
Anode Rod Socket
A specialized socket removes and installs anode rods without damaging the tank. We use it to replace corroded rods and extend tank life.
Descaling Pump
We use a descaling pump to circulate descaling solution through the tank and collector loop. It removes scale and sediment that reduce efficiency.
Inspection Camera
A borescope camera lets us inspect inside the tank and collector loop. We check for corrosion, scale, and blockages without disassembling the whole system.
Pressure Gauge
We attach a pressure gauge to test system pressure and check the expansion tank. It helps us diagnose pressure issues that cause leaks.
