John Thompson Boiler Repairs in Randburg
John Thompson boiler repairs in Randburg. Locally manufactured industrial plant with strong local parts support.
John Thompson equipment we work on includes packaged steam and hot water boilers. Commonly replaced parts on this brand are level controls, burners, refractory, and we keep or source these against the unit's model and serial plate rather than by guesswork.
Boiler repairs cover the burner, the pressure vessel side, the water treatment side and the safety controls. Most lockouts trace back to ignition, flame sensing, water level control or feedwater quality rather than to the vessel itself, and the correct repair starts with reading the lockout history.
Large stock of 1970s–1990s homes with ageing 150–200 L geysers, plus a spread of small commercial and light industrial units along Malibongwe. Element and thermostat failures dominate domestic call-outs in this area. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
